Ekol, the easier, cleaner way to burn wood.

All Ekol stoves are DEFRA Exempt/Approved for burning wood in any part of the UK including any smoke control area, city or town.

20kW DEFRA Approved Multifuel Boiler Stove

There are just a tiny handful of DEFRA Exempt boiler stoves available in the UK. This is due to the fact that boiler stoves by their nature, are far more likely to create smoke. To create a clean-burning boiler stove required a particularly advanced stove design.

At our Advanced Combustion Research Facility we have been able to achieve this by optimising every element of the stove design,

Available in two sizes, they can provide hot water and central heating for upto 18 radiators (Clarity 30) when burning anthracite, or up to 12 radiators (Clarity 20) - (dependent on system and property requirements).

Both the Clarity 20 and Clarity 30 can burn wood logs as well as anthracite and other suitable type solid fuels.

For easy maintenance, access to chimney flue for cleaning is possible through the stove.

The Ultra-Cleanburning Technology of Ekol Stoves which achieves this also makes for an easy to use stove with a unique flame pattern which is simply mesmerising. Less ash is produced, less cleaning of the stove and chimney is required. The result is a much improved experience taking the effort out of wood-burning.

The Clarity range are a State-Of-the Art Hybrid stove, using the ultimate combination of heavy cast iron inner components along with dense refractory firebrick linings and precision engineered outer steel shell up to 10mm thick.
