ETA Heiztechnik Biomass Boilers

Commercial Biomass is a registered and certified installer of ETA biomass boilers, the UK’s bestselling biomass boilers. These domestic biomass boilers can burn either wood pellets, chipped wood, logs, or even miscanthus (a type of elephant grass), while some can burn a combination of these fuels. All ETA boilers are Renewable Heat Incentive compatible, which means they are eligible for government funding. ETA wood burning boilers give outputs from 7kw to 500kw. A 7kw boiler would suit a small house and a 500kw boiler would provide enough heat for a large factory building. These biomass boilers are ideal where heating needs to be economical, environmentally-friendly and automatic.
