Zero emission wood chip boiler

Windhager biomass boilers

We now supply, install and maintain zero emission wood chip biomass boilers manufactured by Windhager. The PuroWIN is the cleanest wood chip boiler in the world, with virtually undetectable emissions. This is due to a very well thought-out design. The word ‘innovative’ is too often used to describe the mundane and the ordinary by advertising executives searching for a superlative, without actually considering the meaning of the word. Windhager have developed a combustion chamber unlike any we have seen in conventional biomass boilers… read more

Want to do your bit to avert climate change? Switch to wood fuelled heat. Good quality biomass boilers are clean burning and output far less carbon dioxide than any other commonly used heating appliances. Electrostatic precipitation and clever burning techniques keep air quality pristine. Low in particulate matter, low in carbon dioxide emissions, low in NOX emissions. Biomass is clean and green.

Think you’re saving the planet with a heat pump? Look at the facts — assuming you’re in an old house trying to make an air source heat pump perform with oversized radiators, your CoP is likely to be around 3:1 at best, meaning that for every 3kWh of heat you get, you use 1kWh of electricity and the other 2kWh comes from the warmth of the air outside. One third of 0.519 is 0.173, which is nine times worse than burning logs, four times worse than pellets and nearly eleven times worse than burning wood chip. Why is the government pushing heat pumps when we don’t have the cable infrastructure to run them all and the majority of the electrical grid is still on fossil fuels and up to 70% of the power produced is lost in transmission? It makes no sense. The replacement for the failed Green Homes Grant scheme funds heat pumps to the tune of £5,000 per household. It has been announced that biomass boilers will be included in the new scheme, after having been excluded in earlier rounds of proposals. Even now, homes will only be eligible for biomass grants if they are off gas grid with a rural/urban indicator of D or lower.
