Biomass is a renewable and sustainable fuel with lower carbon emissions than traditional fossil fuels.
Biomass boilers can provide higher temperatures compared to heat pumps.
The boilers are an easy replacement for a traditional gas system, with no need to replace radiators. They have a lifespan of 20 to 30 years, compared to a traditional gas boiler that would last between 10 and 15 years.
Biomass heating can be an excellent solution in rural areas where there is no gas supply.
Biomass boilers are an excellent way to utilize waste wood.
Key considerations for biomass heating
One of the biggest decisions you will have to make is the type of fuel you will use. The type of fuel can be chosen to suit your location and/or heating needs.
Wood Pellets
Pellets have a high calorific value (resulting in more heat release), are made from raw wood waste such as sawdust, and are easy to transport. Storage and delivery systems must be carefully designed to avoid moisture and to ensure that the pellets do not break up into dust on delivery.
Logs
Logs require careful management to ensure that wet fuel does not cause problems with internal boiler mechanics. Logs are often obtained by labor-intensive manual cutting and stacking, and require dry storage for over a year before use.
Wood chips
Chips can be less expensive than pellets because they often have a higher moisture content, which reduces their calorific value.
Keep in mind that not all areas have nearby suppliers, and you need to know that the fuel will be available for the life of the boiler.
