Emissions and Legislation

Please Check with your local authority that you are not in a smoke-controlled zone.

The most important criteria on installations under 400 kW, is that the smoke must not be a nuisance. When burning damp fuel (such a straw), the moisture has to be driven off as white steam.

This type of smoke is allowed for approximately 20 minutes after re-loading until the water temperature is restored. Smoke can be reduced by fitting an accumulator tank.

When burning waste wood or pallets, you will need to complete a U4 exemption form from the Environment Agency which will allow you to burn your waste product.

The U4 allows you to burn at up to 50kg per hour, which would equate to (as an approximation)  a 240 kW Dragon boiler.

The U4 application can be done online

Please note that the Renewable Heat Incentive is a government backed scheme and that any figures or rules quoted are subject to change by OFGEM and will be correct at the time of writing.


Maintenance of a Dragon boiler is straight forward.

Empty the ash, clean the heat exchanger tubes with the tools provided and check the back box.

 Fuel Types:

All Dragon Biomass boilers can burn virgin wood, waste wood, straw, cardboard, in fact, most dry natural products
