The benefits of burning waste wood , whether it be from pallets,  scrap wood, sawdust or logs is very clear – Cost Savings ! – These workshop wood burning heaters often pay for themselves in a very short period , as the fuel cost is normally zero or negligible , the only cost is for the electricity that powers the fan which is blowing the warm air out of the heater .They also help the environment , as wood is classed as a CO2 neutral fuel ( as wood grows it absorbs CO2 , and when burnt it gives that off – thus neutral)  resulting in CO2 neutral heating – so you can be happy in knowing that your doing your bit for the environment and global warming. Another feature of these workshop wood burning heaters is that they help eliminate your bulky and often expensive to get rid of waste wood product, saving thousands of pounds a year on skip and landfill charges, and turn it into heat for you to benefit from,as well as saving energy usage.

While installing of the “WHT” range of waste wood workshop wood burning heaters all the regulation and corresponding European and local standards have to be followed. Particularly:
EN 13240:2008 Room heaters fired by solid fuel – requirements and test methods
EN 1443:2005 Chimneys – General Requirements
EN 1457-2:2012 Chimneys. Clay/ceramic flue liners. Flue liners operating under wet conditions. Requirements and test methods.

These wood burning warm air heaters are to be located on a horizontal, stable, non-combustible and flat surface with appropriate load bearing capacity. Locating and using these wood burning workshop heaters near flammable materials is strictly forbidden.

Combustion Air Requirements

The area or workshop where the war air heater is to be located must have an adequate combustion air supply ventilation, which will provide sufficient volume for the fuel combustion process.To ensure the correct running of these workshop wood waste heaters it is necessary to supply the heaters with combustion air with at least 10 m3/hour of air volume for every 1kW of heating power and at least 20 m3/hour of air volume per person located in the area being heated.

Workshop wood burning heaters

We also do another wood burning heater, that will also burn solid fuel such as coal, and in reality should be called a multi fuel warm air heater, as it will also burn oils as well. This is called our Kozy Workshop Heater Wood Burner Heater , and looks like this –

The Flexiheat ” Kozy” Wood Burning / Solid Fuel / Multi Fuel – Warm Air Heater

 

 

The Kozy heater range has two models within it , the first is a 20kW Output heater , and this is designated as the Kozy 20 , and the second is the Kozy 30 , which is a 30kW Output model. Both of these wood burning heaters require and are powered electrically by a 240 volt , 1 Phase supply.

You will notice that theses workshop heater wood burner heaters have two access doors-

The bottom one , is the access door to the combustion chamber -when using solid fuels such as wood, coal , paper etc as these are burnt on a metal hearth, which comes as standard with the heater.These warm air heaters also come as standard with a burner basin, which is used when burning oils ( Be it waste oil, 35/28 Second Heating Oil/Diesel/Kerosene,vegetable oil,bio diesel etc) This process ensures that it is very quick and easy to change your fuel type, should you run out of wood or solid fuel as your primary fuel source.

The top access door gives access to the combustion chamber and flue exit – making cleaning the unit easy. This access door is also used to feed the heater with fuel when using solid fuels.

A high capacity axial fan draws air from the area over the heat exchanger and combustion chamber and expels the warm air into the building, providing a constant supply of warm air.

In times of rising fuel costs, the payback period for a Flexiheat Kozy multi /waste oil heater is very short. Utilising your waste wood / logs etc , you can get an effective warm air heater with no fuel costs, and no fees to pay for the collection and disposal of your waste wood. The Kozy in our opinion is the best workshop heater wood burner heater for your workshop or garage available in the UK and Ireland.

As you can see from the above picture the Flexiheat Kozy is a warm air heater that benefits from many years of experience of burning wood and solid fuels and continuous quality control which has allowed us to produce a solid and durable product whilst maintaining a competitive price.Both models come with a 12 Month warranty and are CE approved.

Industrial wood waste burner incinerator workshop heater / Workshop wood waste heaters

We also do what we would call an industrial wood waste burner / incinerator workshop heater range that has an output of up to 70 kW, they differ to the other versions that we offer in that the have a rotating warm air distribution head or diffuser, and similar to our Kozy range they will also burn solid fuels such as coal, but their main purpose is as industrial wood waste heaters. This range of workshop wood waste heaters is called our “FHSPN” range of warm air heaters, with the option of a 35 kW or 70 kW models.An advantage of these workshop wood waste heaters is the quick distribution of warm air heat around the building or workshop by the thermostatically controlled combustion chamber fan , which only switches the fan on when the heater has warmed up enough (35 Degrees C ) ensuring that no cold air is blown.In general these heaters are a stationary multi fuel  war air heater, characterised primarily by their unique easy of use, high manufacturing quality and very high heating performance.

This series of wood waste heaters are warm air heaters generating  thermal heat through combustion of solid fuel such as waste wood, or even coal, directly from the heat exchanger to the outside environment, without any intermediate liquid. During combustion, smoke and other gases are generated, which are ventilated by the chimney / flue pipe, this ensures clean heated warm air  due to the closed combustion chamber.

Thermal heat is generated as a result of combustion in the combustion chamber, which is equipped with a cast iron grid. The thermal energy is transferred from the combustion gases to the ambient fresh air by means of natural and forced convection.

Internal view of the “FHSPN” workshop heater wood burner / solid fuel warm air heater

 

The air and combustion gases are passed through different ducts, which are welded and properly insulated. The emerging combustion gases, after cooling, are led out through a duct that must be connected to a chimney or flue pipe. The chimney or flue pipe diameter must be sufficiently large to guarantee effective combustion gas removal. The air used in the combustion process is taken directly from the room or building being heated. For this reason, it is of paramount importance to provide appropriate ventilation for the heated room or building that will guarantee the provision of an appropriate volume of fresh air. The ash emerging in the combustion process falls to the ash tray, from which it can be removed without difficulty. The heated air is distributed around the room through a rotating blower or head, which is mounted in the top area of the air heater.

The electric switch box with thermostat is responsible for the assurance of electric energy to the heater fan. When the heater outer casing reaches the set temperature (35 °C), the fan is switched on and warm air is distributed around the room, in which the heater was installed.The ventilator / fan is automatically shut down if the heater casing cools down to less than 35 °C.

Permanent use of certain wet fuel types, with simultaneous low combustion gas temperature (less than 160 °C) will cause faster wear of the heater body, corrosion of the convection ducts, the flue and tar deposits in the combustion chamber. This is caused by condensation of the combustion products: water,nitrogen oxides and sulphur oxides, which together form a very aggressive environment facilitating faster corrosion to these wood burning workshop heaters .The wood should be seasoned for at least a year, and have a humidity level of 15% to 20% . Wood humidity exceeding 25% can cause energy losses and damage to the workshop wood burning heater body.
