Domestic Biomass Boiler Range

ETA Heiztechnik

Commercial Biomass is a registered and certified installer of ETA biomass boilers. ETA are the UK’s bestselling commercial biomass boilers. They set the standard for safe and reliable fuel conveying systems, efficiency and innovation. These boilers can burn either wood pellets, chipped wood, logs, or even a type of elephant grass called miscanthus, 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. The boilers are ideal where heating needs to be economical, environmentally-friendly and automatic.

It sounds like a genie might appear… but it’s actually a cheap and pretty good for the money RHI compliant biomass boiler…

Award winning

They’re not. Unless it was an unofficial Ugliest Boiler on the Planet award, but hey — they’re cheap


Well, they claim 94% efficiency without needing a lambda probe, so it makes you wonder why all the premium makes insist on having one
