Product Description

The Baxi Multi Heat Pellet Boiler is a biomass boiler that runs on wood pellets a type of fuel specially designed and produced for use in biomass appliances. Biomass is a fuel derived from organic material, commonly plant matter, and is a far cleaner burning fuel than fossil fuels such Oil, Coal and Gas. This is because Biomass fuel is referred to as 'Carbon Neutral' as the fuel releases the same amount of Carbon Dioxide when burned as it absorbed while growing therefore no additional Carbon Dioxide is being added to the atmosphere. As well as being cleaner Biomass is more energy efficient especially wood pellets which have a specially designed shape density so that they burn efficiently and so the boiler is able to claim the optimum amount of heat that can be generated by burning the wood pellets.
