Biomass boilers in general the wood-fueled heating systems, also called biomass–systems, burn wood pellets, chips or logs to provide warmth in a single room or to power central heating and hot water boilers. A stove burns logs or pellets to heat a single room – and may be fitted with a back boiler to provide water heating and central heating as well. Check the Renewable Heat Incentives in your country (Europe and USA) since you may qualify for subsidies and incentives when installing a biomass boiler in your home or business. The most advanced boilers are fully automatic. They control the amount of fuel and air supplied to the combustion chamber.
