Why choose to go down the electric heating route

There are several options for heating a room. However, not all options are a practical for some properties. In addition, not all locations have the same energy sources, so that a choice must always be made. For example, for a property without access to gas, one can opt for an oil heating system. What if this property is too remote for regular deliveries? Then a great choice is to opt for electric heating.

 

Below are just some of the benefits of using one of our German electric heaters; –

Clean and green – an electric heater, unlike oil or gas gives off no emissions.   They are 100% energy efficient; converting every bit of the input energy to heat. They also reduce environmental impact compared to other fuel types:

No installation costsGerman Electric Heaters do not require any installation. You only have to plug the plug into the socket and the device is immediately ready for use

High efficiency –  German electric heaters are very efficient, because the electricity used is directly converted into heat

Additional heating – German electric heaters are ideal when the existing heating system is not sufficient or more heat is required in the short term. Moreover, they are the perfect solution in the transitional period, i.e. in spring and autumn, when the temperatures are not so low that the central heating must be switched on

Safe to Use – German Electric heaters are distinguished by different safety features such as overheating protection

Portability – electric heaters are extremely versatile and more practical in different situations than other heaters. Therefore, they are often preferred

Quiet and discreet – with the exception of the fan, electric heaters have a very low noise level, therefore making them ideal in smaller rooms

Zonal Heating – because of their mobility, an electric heater is perfect for specific areas that require temporary or permanent heat

 

Make life easy for yourself, with our German electric Heaters, in most instances all you need is a power socket. However, for larger areas three phase models are also available giving large volumes of heat. There are no exhaust gases or smells – just large volumes of safe, fume-free heat. Electric heaters are ideal for virtually any location including

 

  • Offices
  • Shops and showrooms

Commercial Boiler

A commercial boiler is a pressurized system that burn combustible fuel to heat water that is then used to provide heat to your building. Some boilers use the actual hot water itself while others utilise water that has been turned to steam.Be it an hotel, school or hospital boiler, a district heating scheme or any industrial or commercial refurbishment of your heating scheme, you can benefit from our vast experience in supplying commercial heating boilers in the UK and Ireland.

Commercial Boiler

Inside the boiler itself, the burner , wether it be natural gas / Propane (LPG) or Oil  creates heat that is then transferred to the water via the heat exchanger. The process creates either hot water or steam, depending on the type of commercial boiler. The hot water is circulated via pipes throughout your building. The water then enters radiators or other components that divide the heat thus providing the heating you require to keep your indoor spaces comfortable.

Natural gas is probably the most common fuel used in commercial boilers. Other types of boilers are available that burn fuel oil like diesel or heating oil. There are also boilers out there that use electric resistance coils to produce heating from electricity.

 

Common components of commercial boilers

 

  • Burner: A burner is a device for the combustion of a fuel. For example, a fuel oil burner can be mounted on the boiler of a central heating system (oil heating). The burner produces a flame by pressing the fuel oil through a fine nozzle and supplying combustion air with a blower. In the burner start, the flame is usually ignited with an electric arc. The hot combustion gases enter the boiler, which effectively serves as a heat exchanger: the generated heat is transferred to the boiler water to a large extent. Similar burners are operated with natural gas. No atomization is necessary here, only a good mixing of gas and air. The correct dosage of the combustion air is important for a clean and efficient combustion. Ideally, the burner supplies exactly the required amount of air to the flame: by no means too little to allow complete combustion (without the formation of soot or carbon monoxide), but not too much to minimise exhaust gas losses

 

  • Combustion chamber: A combustion chamber is a component in which air and fuel are mixed, ignited and burned to heat the water. The chamber contains the burners and is specially designed to provide a safe and secure area for high-temperature combustion of volatile fuel. The chamber is commonly constructed of steel, cast iron or other heavy-duty metal.

 

  • Heat exchanger: The heat exchanger is an integral component that carries the heat created by the burners to the water in the boiler. Heat exchangers are commonly made of cast iron, stainless steel or copper.

 

  • Controls: System controls allow the user to calibrate water temperature, air and fuel supply mixtures, ignition and internal pressure. The controls regulate when and how often the burner fires, the temperature of the water, the rate at which fuel is used and the quality of the mixture of fuel and oxygen. Commercial boilers can also be fitted with appropriate safety controls that make sure that the internal pressures in the boiler doesn’t get too high, the water temperature stays within a safe range and ensures that the system continues to operate properly.

 

  • Exhaust stack: Also called the flue, the exhaust stack is the series of pipes that divert the exhaust gases away from the inside of the building to the outside. The exhaust stack must be constructed to ensure that any dangerous gases such as carbon monoxide are safely vented away from the interior of your facility.

 

 

Boiler Safety and Maintenance

Commercial boilers can be unpredictable systems containing very hot water or steam under high pressure. Therefore, care must be taken to make sure the boiler is clean and working properly and that all safety systems are functional and ready to work if required. Hot water or steam leaks can pose a serious risk of causing injuries or damage. Commercial boilers can potentially explode, which can result in serious injuries or even death as well as significant damage to your commercial facility.

It is imperative that your commercial boiler receives regular preventive maintenance from a professional heating engineer. This maintenance not only ensures the system works correctly and at its highest level of efficiency but that it also works safely.

Here at Flexiheat UK, we realise that finding and purchasing a new commercial boiler is a complicated business. This is made far worse by the confusing terms used to describe boilers. This is our guide to these commercial boiler technical terms, to help make your search easier.

 

Condensate

The term condensate is used regularly. Throughout the process of producing heat, the boiler will produce some condensation. This needs to leave your building or premises through an outside wall. In addition, some of the condensation will turn to liquid and need draining away. This is normally through a pipe that connects to your pre-existing drainage system.

Condensing Technology

This term has increased in popularity, as modern boilers are all fitted with condensing technology. This means it is capable of condensing the gas into heat for your business. The benefit of condensing technology is that a lot more of the waste gases are recycled and turned into more heat, which is far more cost effective and better for the environment.

Flow Rate

Flow rate is a term used to describe the amount of hot water that is produced in one minute. This is mainly relevant to combi-boilers. The higher the flow rate, the more water produced which means your boiler can work for less time and use less fuel. Essentially a boiler with a good flow rate will save you money on your bills, but is probably more expensive to purchase initially.

ErP Rating

This term refers to the A++ to G ratings, shown on all new boilers. Referring to the boiler’s energy efficiency as well as its heating and hot water performance, the rating allows you to choose the most efficient boiler. A++ is the highest performing and G is the lowest.

SEDBUK Rating

This term means: Seasonal Efficiency of Domestic Boilers in the UK. It is a percentage rating for boiler efficiency and it has been added as part of the overall ErP rating.

 


We at Flexiheat UK hope this glossary helps make choosing a new commercial boiler a little easier. Don’t let the commercial boiler technical terms give you a headache!

Blow Heaters UK

Blow Heaters

Blow heaters are fundamentally any type of heater that is assisted via a fan.  As the term suggests, heat is expelled at a higher rate resulting in faster movement of warm air thus ensuring a more efficient and accurate heat delivery.  There are a range of Blow Heaters on the market. The most common of these is Electric Fan Heaters  which function by heating a coil or a heating conductor. The cold air is led along this heating coil and heated. A fan is then used to transport the heated air into the room. Electric Fan Heaters are usually small and space-saving, which means they can be used almost everywhere and are super-flexible as far as the location is concerned. Only a power connection and a little space is all that’s required.  They are used for heating rooms such as garages, greenhouses, tents and the like. They are often used as additional heating in the living area, because of their fast and effective way of heating the room.


Blow Heaters

Common Applications
Building industry • Heating and drying out rooms, often in conjunction with a dehumidifier.
Industry • Heating of offices, canteens, stores, warehouses etc.
Livestock • Heating poultry houses.
Horticulture • Heating of sorting areas and greenhouses.
Agriculture • Heating of livestock areas, dairy parlours, workshops and packing sheds.

For more information on our range of electric blow heaters, please click here

 

Other popular types of blow heaters are ones fuelled by gas, usually propane or liquefied petroleum gas or LPG, for short.   Most gas blow heaters use a so-called piezoelectric igniter. A material, often crystal quartz, which has the property of developing an electrical potential when pressure is applied is housed in a mechanism that allows a spring strike hammer. This action generates a spark, igniting the gas

Blow Heaters

Common Applications

Livestock • Heating of pig and poultry houses.
Agriculture • Drying of agricultural products.
Horticulture • Heating of greenhouses and polytunnels (N.B. Control CO2 and CO emission)

 

Control

Temperature control is a desirable feature in a gas blow heater. An automatic thermostat is a popular way to achieve this and some of the more sophisticated blow heaters are fitted with a thermostat while others simply have a manual high and low flame control.

Safety

The main drawback of burning propane or other combustible materials, for that matter, in a small and enclosed space is the risk of carbon monoxide poisoning. Carbon monoxide is a product of irregular combustion. It is odourless and it competes with oxygen in the blood, which deprives the brain and other parts of the body of oxygen. Some propane heaters are approved for indoor use and some are not.

The advantages of blow heaters

 

  • Blow Heaters heat the room quickly and effectively to the desired temperature.

 

  • No additional work is required to operate a blow heater. Only one socket and some space should be available.

 

  • The purchase costs of blow heaters are manageable.

 

  • Most models are equipped with practical carrying handles or tramples, so even if the case is still warm, they can easily be moved locally.

 

  • The most compact design of the devices allows them to be used in a very small space.

 

  • Due to the existing “cold stage”, the units can be used as a fan in summer.

 

  • Integrated or external time switches allow time-controlled use.

 

  • Many appliances can be used as frost monitors without an external thermostatic control unit.

Commercial Heaters UK -A Guide to

Commercial Heaters – Your Options

Commercial heaters are frequently used in almost all the industries today right from manufacturing , car show rooms , retail units to warehouses . There is a variety of heaters that serve different purposes. As an unavoidable necessity, it is essential for businesses to install a commercial heating solution in their premises, to either keep they’re staff or customers , or even both satisfied. Commercial heaters can also be used to keep products above certain temperatures to ensure no damage to them , such as frost protection etc.

Installing them may be an easy task as you simply order the supplier or warm air heating installer to do so, yet the most challenging part lies in different types of questions and queries before installing-

Please go through the following points if you want to get the most out of your commercial heating equipment –

 

First of all, make an in-depth assessment of what your heating needs exactly are. Looking at the devices randomly may take you on the wrong route.

 

The following are the most common types of commercial heaters on the market based on fuel types

 

Commercial Gas Heaters and Propane(LPG) Heaters

 

Commercial Gas heaters burn a variety of either natural gas, propane (LPG),  natural gas (NG) or other gaseous fuels to generate heat. Early gas heaters were similar to the Bunsen burner in that both they used a flame to heat air locally. This heated air was spread by convection to warm an entire area. Later, the burner’s flame was used to heat a structure made of asbestos, a strong and incombustible fibre. Although asbestos structures have been replaced by fire clay and other refractory materials, modern gas heaters still operate according to this principle but the refractory materials have now been replaced by a combustion chamber and a heat exchanger, which means that any products of combustion are now expelled via a flue pipe system, being infinitely safer than the early days. They are often Co-Axial flued , or sometimes referred to as room sealed , whereby they take the air required for combustion form outside the building , via a twin piped flue system, this results in higher efficiency as the building is more air tight . Both natural gas commercial gas heaters and propane commercial heaters often use similar designs, the only difference is the gas burner.

Commercial Suspended Gas Heaters – In a Garden Centre

 

According to their radius of effect, gas heating systems can be divided into two types: the so-called gas convector and gas-turbine heating.

 

With gas convector is heaters, which are used primarily for heating individual rooms. The heat generated by the combustion of the gas is then discharged directly to the environment. The gas-turbine heating, on the other hand, is generally used as a central heating system to supply entire buildings

Commercial Heaters – Gas or Propane – Applications

There are a broad range of different applications for gas and propane heaters. Below are just some examples;-

  • Industrial Applications
  • Warehouses
  • Workshops
  • Garages
  • Greenhouses
  • Offices and Shops 
  • Retail Outlets

 

Features

There are a whole host of optional features for gas heaters. Some are indirect-fired, some are corrosion resistant, some are finned and some are even explosion-proof others are designed to provide dynamic power regulation . They can feature custom designs or have a secondary heat exchanger ( condensing warm air heating) for maximum heat transfer. Gas heaters can also be fitted with an external temperature sensors and multiple / independent timing controls to suit the site conditions

 

Commercial Heaters – Oil – Gas Oil or Kerosene 

 

Oil commercial heaters predominantly burn fuel like heating oils such as gas oil or kerosene to generate heat but waste or used oils are also a popular fuel source.

Types

There are many different varieties of oil and kerosene commercial heaters.

Probably the most common are stationary cabinet’s types. These are usually floor mounted and either blow out warm air through their vents or through duct.

Commercial Oil Heaters – Used in a Greenhouse Heating application

Operation

Oil and kerosene commercial heaters transfer heat to a room over a longer period of time and at a slower rate. When the oil burner is engaged, heating oil travels from the tank or reservoir to the burner by way of a pump where it becomes a fine mist mixed with air. The fuel/air mixture is then injected into the burner where it is ignited in the combustion chamber of the heater, which then transfers the heat via a heat exchanger to the space being heated.

 

Specifications

Oil and kerosene heaters use single-phase or three-phase power.

 

Applications

There are a wide variety of applications for oil heaters. Examples include;

 

  • Warehouse & Factory heating
  • Drying,
  • Melting,
  • Annealing or heat treating,
  • Curing or tempering
  • Operations with gases and vapours,
  • Clean water heating
  • Heat process and high-purity waters,
  • Lightweight oils & degreasing solutions,
  • Heavy & medium weight oils,
  • Mild & severe corrosive solutions,
  • Caustic solutions and liquid paraffin.

 

 

Commercial Heaters – Electric Heaters

 

Electric heating systems are  heaters which produce heat via heating wires or heating coils. They can be roughly differentiated according to whether they store the heat, store it in part or deliver it directly or whether the heat is generated by infrared radiation or by the heating of air.

 

Types

There are many variants of electric heaters. Below are the main types

1 – Natural convection

The portable heater with natural convection resembles a standard heater. It settles on the ground and heats up slowly.

Operation

  • Fresh air rises inside the cabinet by convection.
  • The air is then heated by an element.
  • The hot air exits through the openings and rises into the room.
  • There is no fan on this type of appliance.

Advantages

  • The natural convection heater keeps the temperature constant, provided the room is closed or not too large.
  • Silent.

Meets the needs

  • Ideal for use for several hours at a time, for example, at the chalet or at night, in a room when the central heating of the building is switched off.

 

2 – Forced Convection or Blow Heaters

 

The forced convection heater, also referred to as forced air or blow heaters are a very popular model. These heaters are often small and light and distribute the heat with a fan.

 

Commercial Heaters

Commercial Electric Heaters

 

Operation

  • A fan moves the air around the heating elements and pushes it forward.
  • In ceramic models, electricity passes through ceramic plates that store heat in their mass, and then a fan spreads it.

 

Benefits

  • Small and light.
  • Rather stable temperature in a closed room.
  • Heat sensation faster than with fanless model.
  • Allows directing of heat.

Meets the needs

  • Ideal for rapid heating distributed throughout a room, even when the area to be heated is large, then we do commercial electric heaters with an heat output of 80 kW , which we think are the largest portable electric heater on the UK market to date

3 – Commercial Heaters -Radiation (radiant heating)

 

The radiant heater, also called radiant heating, often looks like a standing fan or cabinet heater. It heats according to the same principle as the lamps used on terraces. It can therefore heat a person very quickly!

Commercial Heaters

Commercial Portable Electric Infrared Heater

 

Operation

  • Uses a very hot element, usually halogen or quartz.
  • The element produces an infrared wave that quickly gives a sensation of warmth in a precise direction.

Benefits

  • Quiet.
  • Sensation of immediate heat, much like the rays of the sun on a winter day; Warms bodies and objects, but not directly air.
  • Allows directing of heat.

 

Meets the needs

  • Ideal for directly heating a person in a room with a high ceiling (because hot air is rising) or in a room where there are drafts. Because of the risk of burns, it is not ideal when there are young children or elderly nearby.

 

Features

Some of the key features of electric heaters are portability, precision temperature monitoring & control and design flexibility

 

Applications

Electric commercial heaters are commonly used throughout industrial and consumer products to heat all types of liquids, gases, vapours, and solids. In consumer products, electric heaters are commonly used for heating water, air and even flooring. Industrial warm air heating applications can utilize much higher wattages and these industrial electrical heaters can be used for applications such as heat treating for pest control , for drying of products etc, as well as standard space heating

 

Advantages of Commercial Electric Heating

  • Low cost in purchase
  • Low installation costs, since no piping necessary
  • No space required for burner or fuel storage
  • No chimney
  • Maintenance costs are eliminated
  • Good solution for temporarily heated rooms or buildings
  • No or little dust swirling, good for allergy sufferers

 

How to calculate how much heat you require , to get your correct commercial heaters or heater

Once you have determined the type of heater for you building you then need to work out which size you require. This can be achieved in the form of a simple heat loss calculation. The most important factors to consider are the dimensions of the building, the length, width and average height. There are a number of online calculators that you can use to work out the heat requirements.  The answer will typically be given in kW (kilowatts) of BTU (British Thermal Units)

Once the appropriate type of commercial heater has been decided and then installed it is advisable to appoint experienced operators at your factory premises so that they can ensure the heater(s) function correctly

Space plays a vital role as far as the correct installation of these apparatuses is concerned. Take measurement of the space where the device or devices are to be installed.

Gas Heaters UK – What’s your options ?

Gas Heaters UK

Gas Heaters UK – Natural gas is a fossil fuel that releases almost no classical pollutants during combustion. It has the lowest carbon content and the highest hydrogen content of all fossil fuels.

In terms of the same energy content, about 25 percent less carbon dioxide (CO2) is produced when burning natural gas than when burning fuel oil. In terms of fine dust, too, natural gas, compared to wood and oil, has a considerable advantage due to the absence of carbon black. One cubic meter of natural gas contains around 10kWh of energy

Natural gas is very affordable, so running a gas heater can be budget friendly. This type of gas is also very clean, so it is good for the environment, which is an additional benefit of using a gas heater.

Most gas heaters are designed to turn off if they fall over or overheat. This safety feature makes gas heaters even safer for your home or office.

These types of heaters provide a very warm heat and are excellent for supplementing an existing heating system. Natural gas is a popular heating option for commercial and industrial locations because it provides a very comfortable heat, making the area feel warm and cozy all winter. Gas heaters are also extremely effective and can be used in a variety of places.

Industrial Space Heater UK – Your Options

Industrial Space Heater

Industrial Space Heater – Is the heating bill for your plant or warehouse too high? What about cold dock door areas and unbalanced temperatures? Is negative building air pressure a problem? Have you experienced employee complaints and lost productivity from heating or indoor air quality problems? Do you have high maintenance costs for existing heating equipment?

There are only a few common problems that result from choosing the wrong heating system, using obsolete heating/ventilating equipment or simply miscalculating space heaters

Annual space heating costs are a significant part of operating budgets for industrial units, manufacturing plants and large warehouses. Selection and application of the proper space heaters can reduce annual energy costs more than 60% and increase company profits.

What factors determine the best space heating system? Everyone wants a heating and ventilating system that meets their unique requirements at the lowest total cost.

Prior to selecting a heater you must first decide the heating/ventilating requirements and understand all the cost factors that determine the true lowest total-cost solution for a specific facility.

 

Industrial Space Heater and Space Heating Systems

A gas-fired heating system usually offers the most cost-effective way to heat industrial buildings. Oil-fired and electric heaters are sometimes used for specific space heating applications or when gas is unavailable.

Gas-fired space heating systems are classed as being either direct fired or indirect fired.

Indirect-fired heating systems use a method of heat transfer, such as a heat exchanger, which lowers overall energy efficiency. A flue is needed to vent the products of combustion outside the building. The inside air is re-circulated with little or no provision for ventilation with outside air. There are two popular types of indirect-fired heating systems.

1.Boiler systems (hot water and steam) have historically been a major source of industrial heat and power. These centralized systems were often used for space heating when energy costs were low, or when steam was a by-product of boilers used for nearby process heating applications.However, industrial boiler heating systems are becoming a thing of the past due to rising energy prices, poor efficiency, uneven heat distribution and high maintenance costs. Many large facilities are now replacing space heating with boilers with efficient gas or oil fired space heaters and use the energy savings to pay for the new equipment.Although condensing boiler technology has improved greatly over the last decade, and “wet systems” are still very popular.

For more information on our range of condensing gas boilers or condensing oil boilers , please click on the links  for further information on our ranges. These “wet heating systems” often use a unit heaters or sometimes referred to as a  hot water unit heater or steam unit heater ( if utilizing steam as the heating medium ). These are pictured below , and are basically an industrial radiator with a fan behind them that blows out the warm air.

Hot Water or Steam Unit Heaters

 

 

 

2.Unit heaters are a proven method of heating small, open spaces. Multiple heaters are installed around the perimeter of a building to match heat losses. The benefits of unit heaters include redundancy in case one unit fails, intermittent fan operation that reduces electrical costs and installation on the ceiling or mounted on walls to not take up floor space. Due to a limited air throw, their efficiency can decrease with increased height above the floor.

 

Industrial Space Heater

Standard Gas Unit Heaters – Efficiencies of 91%

For more information on our range of standard gas unit heaters, click here for our standard range or here for our premium range , which has a stainless steel heat exchanger and combustion chamber

The initial installed cost is relatively low for small facilities that only require a few  industrial space heaters but the costs can be higher for large buildings that require multiple heaters. A proportion of heat and energy will escape up the flue. Typical overall efficiencies can vary from 85% to 91%, and these industrial space heaters can be used in a room sealed configuration , meaning that the combustion air that is required is taken from the external air to the building.  This industrial space heater technology has moved on greatly over the last 5 years or so , with the development of  warm air condensing technology , which has resulted in this industrial space heater range achieving efficiencies from 96.6% to 108% , with a pre-mix gas burner with low NOx emissions (class 5) form more information on this range click here.Both the standard or condensing range of  these industrial space heaters ( commonly known as unit heaters ) can be fired by either natural gas or propane gas. There is also an option to have a oil fired suspended industrial heater , please click here for information on this range , which goes from 52kW to 209kW.

 

 

Unit heaters are often used in partnership with make up air heaters in industrial plants or warehouses with constant or variable exhaust loads to provide ventilation.

Industrial Space Heater – Floor Standing Option

If floor space is available, quite a few people opt to have a floor standing industrial heater, as these are often more easily installed , as they are at low level , negating the need for lifting equipment and other associated problems when installing an industrial space heater , pipework etc at high level. They are also easier to service and maintain  at low level , something which needs to be considered when selecting your appropriate industrial space heater. These can be fulled by either gas ( both natural gas or LPG , and even waste oil , bio oil or vegetable oil with one of our multi oil burners ).Here is an example of one looks like , with standard distribution heads –

Warehouse Heaters UK – What are you options ?

Warehouse Heaters

Warehouse Heaters – It’s essential that when you’re working in a warehouse, it is heated in a sufficient way in order for your business to run correctly and smoothly. Without the correct heating, your warehouse wouldn’t be a suitable place for your employees to be working in.

The Warehouse Itself

Deciding on the right heating system will depend on several factors, such as the layout of the warehouse. Having big doors constantly opening and closing makes it difficult to control the temperature and, consequently, makes it more difficult to keep it at adequate levels. If your warehouse is very big, your heating needs will vary, compared to a smaller warehouse. You might just need heating in specific areas, so it’s important to make sure you’re getting the right solution for your warehouse.

Warehouse heaters – their applications  

It’s important to ensure that your warehouse is well heated throughout the winter to make sure your employees have a suitable working area.  As the colder days and nights begin to come in, your warehouse will probably require to be warmed up. Some warehouses will need the whole place warming up, whereas others will just require a particular area warming up.

There’s a number of different ways you can heat your warehouse.

Types of warehouse heaters

The next step in heating your warehouse is choosing a heating system. You need to find the solution that works best for you, so it’s important to note the differences between types of heating, so that you know what you have to work with. Heaters tend to include:

Floor standing cabinet heaters – if you prefer, or if your space isn’t at a premium, you might want to check out floor standing heaters, which are available in a number of possible installations: vertically, horizontally or even on the exterior of your warehouse – this is because these heaters have several heat outputs and burners, so their versatility makes them incredibly useful in the workplace. Floor standing heaters can be equipped with either Oil, Gas or in some case Multi / Waste Oil burners depending on the type of fuel source is preferred. Floor standing warehouse heaters are the easiest of all to maintain, as access is granted at any time, without the need of scissor lifts or any scaffolding etc, that you may need when having suspended heaters to service. Flexiheat have a wide range of floor standing cabinet heaters to suit any application

Portable Dehumidifier

Portable Dehumidifier – the battle against damp

Whether in the living room, in the bedroom or on the building site: an excessively high humidity in the surrounding air is almost always associated with the formation of condensation water. The water vapour contained in the air deposits on cool surfaces and causes undesirable condensation water, which can cause considerable damage to the immediate environment. Corrosion and mould formation are the most frequent consequences and not only attack materials and walls but also pose a health risk to you and your fellow human beings.

If you want to prevent the formation of condensed water and its negative effects on man and the environment, the use of a dehumidifier is indispensable. Only a dehumidifier helps you quickly and efficiently remove the surplus water vapour from the ambient air. Reduce the humidity to an appropriate and harmless degree and consciously ensure a comfortable living environment.

The right Portable Dehumidifier for your home

Do you have problems with damp walls, mouldy wallpaper or water formation on the window pane? Do not hesitate, but use a portable dehumidifier to lower the humidity in your home. Provide rapid and long-term remedial action to prevent damage to your building structure or health.

Dehumidifying performance

The dehumidifying performance is an important feature and should be considered for every room dehumidifier. This value specifies how much moisture can be removed from the ambient air in a certain time interval. The dehumidifying performance is expressed in the unit of litres per day (l / d) and is typically in a range between 10 and 60 litres per day in a smaller portable dehumidifier. In the run-up to a new acquisition, you must therefore determine the room size as well as the moisture content prevailing there and then select a portable dehumidifier with a corresponding dehumidifying capacity.

Using a Portable Dehumidifier in basements and cellars

A dehumidifier can also be used for basements and cellars. These rooms also have a high humidity risk; since little is aired, are often closed, and the dampness rapidly settles on cold walls. This ensures a perfect breeding ground for mould.

For basement and cellars , it is also advisable to install a portable dehumidifier. To prevent moisture damage and mould. The larger the space, we recommend a room dehumidifier with more recording capacity. A Basement or living spaces have different demands on a dehumidifier. A cellar with moisture problems is typically more moisture entry and is not so well heated like a living room. Often, even moisture, which from the summer into the walls, must be dehumidified in winter. In living areas, it is important that the humidity new entry is eliminated as quickly as possible to prevent mould growth. In addition, a low humidity is also useful, because less energy is required to heat the rooms.

Therefore, typically dehumidifiers with a higher capacity are needed in the basement. To reflect the lower ambient temperatures, it is important that the average evaporator temperature is low enough to dehumidify

Portable Dehumidifier in a Garage

Rust and corrosion is your car’s biggest enemy. And they are hiding in your garage – in the form of moisture in the air. Together they cause steel and iron to rust. And what happens next, you know only too well. Rust will make your car’s material absorptive and you will have to invest la considerable amount of money to get it back to working order.  So , in order to ensure that your well-loved car is protected, not only do you need an extensive care routine and to have it routinely  inspected, but it is equally important to have a good garage environment, where you know that your car is being well looked after. And at the end of the day, it all comes down to the level of relative humidity which should not be above 50%. Below this level it is virtually impossible for rust to form. But be advised! If the level should rise, corrosion will rapidly increase, so use a portable dehumidifier to prevent this.

Around the clock protection

The reason for moisture build-up on your car in the garage is relatively easy to understand. When it is warm, the atmosphere absorbs moisture over the course of the day.  Overnight, when there is a drop in the temperature, any moisture created will then settle on your car. The reason for this is simple: Cold air holds less moisture. If the air temperature decreases by as little as 10°C, the relative humidity will rise by over 30%. There is also another problem. The body of your vehicle is full of hidden crevices and hollow cavities.  Moisture resides in these crooks and crannies and in the hollow cavities where the corrosion conditions are ideal

A Portable Dehumidifier in a shed or garden house

Condensation and damp problems are not solely limited to the home environment but can also occur in sheds and garden houses.

The root cause of damp in sheds is often as a result of a lack of heating and ventilation, as sheds are predominantly a cold environment. In an unheated closed space such as a shed the air temperature rises and decreases very quickly, sometimes the dew point is reached and dampness advances out of the air and onto to the items that are being stored, making them damp.

By winter the temperature often does not rise enough again to dry out this dampness causing items to become damaged. Many people find their garden tools rusted, or when opening their shed or garden house experiences a frosty, stale smell or even mould.portable dehumidifier

To ensure that the garden tools and garden furniture stored in a shed are well protected over autumn and winter, it is important to keep it dry in order to avoid corrosion and mould. But, how do you create a dry space, which is exposed continuously in damp and cold?

Firstly it is important to make sure that the shed or garden house is inspected from outside. Joints, cracks, or holes must be repaired, otherwise water or moisture would be absorbed in the rain or moisture and moisture damage could occur.

Since the shed or garden house is potentially closed for a long period and has little ventilation, it would be advisable to place a room dehumidifier in there. It will regulate and control the excessive moisture continuously. This will help prevent too much moisture in the room while at the same time preventing mould and corrosion. Garden furniture and gardening equipment can then be stowed away in a dry damp free environment


The air in the rooms should not be too dry, but not too moist. This applies to industrial and commercial as well as to private use. Because of a balanced indoor climate, not only the building fabric and sensitive products but also the human being. The professional dehumidifiers from Flexiheat are suitable for all drying applications and are therefore clean and reliable. The TE & TK industrial dehumidifier range are used to ensure optimal production and product safety as well as the value of machines, inventory and buildings. They feature flexible and powerful dehumidification, even at low dew points. Compact, lightweight and stackable, and at the same time powerful in dehumidification:

Flexiheat offer portable dehumidifiers that are the economical solution to prevent moisture, mould, mud and smells, while at the same time producing a healthy living environment.

Industrial Heaters

Industrial heaters are frequently used in almost all the industries today right from warehousing, manufacturing , to food processing. There is a variety of industrial heaters that serve different purposes. Being an unavoidable necessity, it is very important for business owners to install a warming solution in their factory premises to serve their purpose.

Installing them may be an easy task as you simply order the supplier or dealer to do so, yet the most challenging part lies in different types of questions and queries before installing-

Please go through the following points if you want to get the most out of your heating devices-

First of all, make an in-depth assessment of what your heating needs exactly are. Looking at the devices randomly may take you on the wrong route


The following are the most common types of heaters on the market based on fuel types

Industrial Heaters – Gas Heaters and Propane(LPG) Heaters

Gas heaters and propane heaters burn natural gas, propane, liquefied natural gas (LNG) or other gaseous fuels to generate heat. The first gas heaters were similar to the Bunsen burner in that both they used a flame to heat air locally. This heated air was spread by convection to warm an entire area. Later, the burner’s flame was used to heat a structure made of asbestos, a strong and incombustible fibre. Although asbestos structures have been replaced by fire clay and other refractory materials, modern gas heaters still operate according to this principle. Gas heaters and propane heaters often use similar designs.

 

Industrial Heaters

Performance Specifications

Specifications for natural gas heaters and propane (LPG) heaters include maximum temperature, heating capacity and maximum air flow. There are two parameters for maximum temperature, maximum air temperature and maximum operating temperature.

The maximum operating temperature for gas heaters is the highest temperature that the heater’s coating or protective cover may reach.

The maximum air temperature, as its words suggest, is the maximum temperature of the air exiting from the heater.

Heating capacity is the wattage that gas heaters and propane (LPG) heaters can deliver.

Insulation

Gas heaters and propane heaters differ in terms of insulation. Choices for insulation include ceramic, magnesium oxide, fluoropolymer, mica, mineral and fiberglass.

Industrial Heaters – Applications

The variety of different applications for gas and propane heaters include annealing and heat treating, drying, curing and tempering, melting, and the heating of gases and vapours. Gas heaters and propane heaters are also used to heat clean water, high purity waters and process waters, lightweight oils and degreasing solutions; heavy and medium weight oils, caustic solutions and mild and severe corrosive solutions.

Industrial Heaters – Features

There are many optional features for gas heaters. Some products are indirect-fired, corrosion resistant, finned, and explosion-proof or can be controlled by a microprocessor. Others are designed to provide dynamic power regulation and for cryogenic applications. They can feature custom designs or have an encased coil for maximum heat transfer. Gas heaters can also be fitted with an internal temperature detector, a grounding wire, and multiple / independent timing controls. Other additional features may also include overheat protection, thermostat control; portability and approval by the relevant authority i.e  British standard or European Standard .certification is available from the manufacturer.

Industrial Heaters – Oil Heaters and Kerosene Heaters

Oil and kerosene heaters burn liquid petroleum products to generate heat. They consist of metal columns with cavities and a heating element. Inside these cavities, oil or kerosene flows freely around a heating element. This element, which is located at the bottom of the heater, transfers heat through the fluid in a process called convection. The oil or kerosene acts as a heat buffer or reservoir and provides both a relatively high specific-heat capacity and a high boiling point. Because of its high specific-heat capacity, the oil or kerosene accumulates a large amount of thermal energy in a small volume. This high boiling point allows the fuel source to remain in the liquid phase, and means that oil heaters and kerosene heaters do not have to be high-pressure vessels.

Industrial Heaters -Types

There are many different types of oil and kerosene heaters. The variety include air, band, coil, and cable heaters; drum, duct, and enclosure heaters; and flexible, forced-air, immersion, and induction heaters. Cartridge, cast-in, ceramic fibre, and circulation heaters; Heat torches are forced-process air heaters that may burn oil or kerosene. Oil and kerosene heaters also include over-the-side, radiant flat panel, infrared (IR) and radiant reflective process heaters. Radiant heater elements are used with both radiant reflective and radiant flat panel heaters. Other types of oil and kerosene heaters include room or space heaters, steam injection heaters, along with strip, tubular, and water heaters.

Industrial Heaters

Operation

Oil and kerosene heaters transfer heat to a room at a slower rate and over a longer period of time. Using the liquid petroleum as a heat reservoir, they transfer heat via conduction and radiation. Typically, the columns of oil and kerosene heaters are made of metal and constructed as thin fins. In this way, the surface area is large in relation to the volume of the heat reservoir.

Specifications

Specifications for the heating element include length or height, depth or thickness and width or diameter, some oil and kerosene heaters use single-phase or three-phase power. Others require AC voltage. Typically, industrial heaters use AC voltage instead of DC voltage.

Applications

There are a variety of different applications for oil and kerosene heaters. Examples include;

  • Drying,
  • Melting,
  • Annealing or heat treating,
  • Curing or tempering
  • Operations with gases and vapours,
  • Clean water heating

Oil and kerosene heaters are also used to heat process and high-purity waters, lightweight oils & degreasing solutions, heavy &  medium weight oils, mild & severe corrosive solutions, caustic solutions, and liquid paraffin. Depending on the application, insulation options are also important to consider when selecting an oil or kerosene heater.

Industrial Heaters – Electric Heaters

Common electric heating coil Electrics heaters generate heat by passing an electric current through a high-resistance material. These heating devices have been adapted for commercial, industrial and consumer applications.

Electric heaters radiate heat with the use of a flat panel emitter, radiant reflective element, tubular element, flexible heater element or other type of heating element. A heating element is usually made up of a coil, ribbon (corrugated or straight), or strip of wire that gives off heat similar to a lamp filament. When an electric current passes through it, it glows red hot and converts electrical energy into heat.

Types

Heating elements are mostly either iron-based or nickel-based.  Nickel-based heating elements are typically made of nichrome, an alloy that consists of about 80% nickel and 20% chromium. Nichrome is a popular and common material for heating elements because of its high melting point of 2,550°F (1,400°C)

It also will not oxidize at high temperatures and does not expand much when it heats up. It also retains a consistent resistance of about 10% between ambient temperature and maximum operating temperature.

 

Industrial Heaters

Features

Some key features of electric heaters are portability, precision temperature monitoring & control and design flexibility

Industrial Heaters – Applications

Electric heaters are commonly used throughout industrial and consumer products to heat all types of liquids, gases, vapours, and solids. In consumer products, electric heaters are commonly used for heating water, air and even flooring. Industrial applications can utilize much higher wattages and industrial electrical heaters can be used for applications such as heat treating, annealing, melting, and the heating of all types of process fluids.
