Industrial Electric Heaters – Output Range – 3kW to 42kW
Industrial Electric Heaters from Flexiheat UK– Our range of industrial electric heaters with outputs from 3 kW in single phase to 110 kW in 3 Phase, Flexiheat UK has a complete range of industrial electric fan heaters to suit both the industrial and commercial electric warm air heating requirements from small to large areas.
Applications for Industrial electric heaters
Industrial electric heaters are rarely used as the only heat source in the workplace. More typical is that the mainstream heating might lack capacity in the coldest weather, or may not quite reach certain areas of the building. Industrial fan heaters are perfect as a source of supplementary heating. In some applications, the lack of a centralised heating system or mains gas supply forces companies to use electric industrial fan heaters as their primary heat source. Whatever application they are used be it as supplementary heating, emergence heating or as the a primary heating system, these electric industrial heaters are high in their effectiveness, versatility, relative low-cost and ease of installation.
These industrial electric fan heaters are a very safe form of warm air heating as neither naked flames ,nor potentially poisonous emissions are produced such as carbon monoxide ,making these industrial electric fan heaters particularly suitable for use in special applications where the use of traditional fuels such as oil or gas is not permitted. They can also be used in closed environments, as no oxygen is required for these industrial electric warm air heaters to work. You can also use these electric industrial heaters in a fan only or ventilation mode, which is great for moving air around in the summer months.
Typical applications for our range of Industrial Electric Heaters are;-
● Suitable for most Industrial and Commercial electric warm air applications
● Dockyards and ship building
● Power stations
● Factories & Warehouses
● Construction sites
● Processing plants
● Events & Marquees
● Military Installations
● Exhibition halls
● Temporary Buildings
Industrial electric fan heaters – How do they Function ?
The heating elements generate heat by the Joule effect and the axial fan produces an airflow that is warmed up as it flows around the heating elements. Clean, warm air is discharged from the front outlet.The heating function is controlled by the built-in safety/room thermostat to keep a constant temperature and to prevent overheating.Most of our industrial electric fan heaters can also be fitted with a remote room thermostat to as an optional extra.
The use of a thermostat provides an automatic room climate control and the adjustable thermal output allows adjustment of the heaters performance to different heating needs and to reduce energy costs.
- Output Temperature and the Delta T of Industrial electric fan heaters
Delta T is the Industrial electric heater manufacturers ” trade terminology” for temperature change across a heater. In the case of industrial electric heaters, it is the difference between the air temperature going in and that coming out. It varies from heater to heater and indeed in any one heater it will depend in the heat setting and fan setting, however where a fan heaters specification states a delta T (sometimes abbreviated to ΔT°) it means at the maximum heat and maximum air flow. It is typical of industrial electric fan heaters to have a ΔT° of between 40 and 55°C. Where higher temperature output is required care is need because fan heaters are designed to operate within a temperature envelope so that if a heater produces a high temperature beyond its design envelope (which can happen if the airflow is restricted) then the thermal overload will switch off the elements. If you need a heater to produce a higher temperature lift, or if the heater is part of a process re-circulation system, let us know and we can advise you on a solution.
- Our industrial electric heaters are well made, durable and robust, everything you would expect from a commercial and industrial manufactured product, the are also –
The heat is dispensed efficiently and in a concentrated way to the ambient air by a powerful fan.
These industrial electric space heaters do not use up any oxygen and they do not give off any unpleasant odours, or dangerous gases so they can be operated in rooms which have bad or even no means of ventilation. Temperature can be adjusted and is controlled by a inbuilt thermostat. The unit can also be used to ventilate rooms as well if so required. They can be used instantly where electrical power is available
- Robust and safe:
All appliances are VDE checked and thermally protected. The heating elements have a stainless jacket and the casing is manufactured from galvanised steel sheet, which is then stove-enamelled , resulting in durable and robust industrial electric fan heaters.
Industrial Electric Blow Heaters – Health & Safety Factors
As no vapours,exhaust gasses or odours are given off , as well as no naked flame- which is very important these days as many building insurance policies insist / have banned a naked flame heaters, due to fire risk, and often make in mandatory for insurance cover for a building that these type of direct fired warm air heaters are not used. These industrial electric heaters can be used in many applications that direct fired diesel or gas heaters cannot.
Industrial Electric Space Heaters -How to calculate what your heat requirement is for a given area ?
To establish what output industrial electric heaters or heater you need, just do the following –
First calculate the volume of your building / area in metres cubed (m3)
Then multiply this by 33 Watts (W) per metres cubed , then dived by 1000 , and this will get you the result in Kilo Watts – (kW)
An example would be – 200 (m3) x 33 (Watts) divided by 1000 ( to get into kilo Watts ) = 6.6 kW Total Heat Requirement
This is a general “Rule of Thumb” calculation, and is based on a high insulation value ( U Value )

Running Costs for Industrial Electric Heaters
Using an Industrial Electric Heater remains one of the most cost effective solution for providing emergency or supplementary heat for a particular space in your home ,office,site cabin or warehouse with electric heating
To work out an accurate running cost for an industrial electric fan heater you can use the below calculation:
Calculating an accurate running cost can vary from room to room because of many factors for example, number of doors and windows, building condition, insulation levels etc. However the following calculation can be used to provide a general idea:
Energy input (kW) x pence per kWh= running cost.
For example a 3kW fan heater run continuously (without stopping) for 1 hour would be:
3kW x 14 Pence/kWh = 42 Pence per hour
The calculation above is based on 14 Pence per kWh – please check with your current electricity bill for the exact hourly rate you are currently paying.
Premium Industrial Electric Heaters – Zinc Plated – Up to 20kW Output – Digital Control
We also supply a upgraded or premium industrial electric heater , called the “FHNXG” range. This range of unit heaters benefits from a zinc plated housing and a more capable control system. It has a digital control system that allows you to –
Delay start -Programmable On feature – This feature enables the user to postpone the starting time of the industrial electric heater by up to 99 hours.
Delay stop – Programmable Off feature – This feature enables the user to extend the operation of the industrial electric heaters by up to 99 hours.
Post ventilation – This feature (setting time between 1-9 minutes) enables the heater to cool down before eventually switching off. This saves and utilizes the energy to it’s maximum, as the residual heat is fully utilized, and blown into the area that is being heated.
Ventilation only mode – This unit can also be used in a ventilate only mode which is useful in the summer months to move hot or stagnant air.
Digital Temperature Control – These industrial electric heaters can automatically control the room temperature up to a maximum of 35 Degrees C. The heater will automatically come on , if the room temperature falls under the desired temperature you select ( up to and including 35 Degrees C) , the heater automatically switches off when that temperature is achieved.
The “FHNXG” industrial electric heaters , benefit form a handle that makes moving and transporting the heater easy. This handle also also doubles as a security rail which prevents damage from being dropped or hit by another object, which can often happen on site , especially building sites.These industrial electric heaters are also stack-able, ensuring a small area is required if the units are put into storage whilst not in use, which is another handy feature of these electric heaters.
