Biomass systems are also known as a wood fuelled heating systems. They burn wood pellets, chips or logs to provide warmth in a single room or to power central heating and hot water boilers.

A biomass stove burns logs or pellets to heat a single room and may be fitted with a back boiler to provide water heating as well. A biomass boiler is connected to a central heating and hot water system.

You should consider the space you have available for both the boiler plant room and fuel storage. The larger the storage facility, the less fuel deliveries you will need.

The design of any heating system is critical to its success. Thermatech have had over 20 years of industry experience in design and installation of domestic and commercial biomass.

Benefits of Biomass

  • Reduce your electricity bills and cut your carbon footprint.
  • You could be eligible for a grant from the Boiler Upgrade Scheme.
  • Every stove or boiler will need an appropriate flue. You will need a flue which meets the regulations for wood-burning appliances. This could be a new insulated stainless steel flue pipe or an existing chimney, though chimneys normally need lining to make them safe and legal.
  • Boiler vs stove: Boilers can be used in place of a standard gas or oil boiler to heat radiators for a whole house, and to heat the hot water. Stoves are used to heat a single room, usually in conjunction with other heating systems, but may also have a back boiler to provide hot water.

Chips, Pellets or Logs?

Chips are used to heat larger buildings or groups of houses.

Pellets are much easier to use and much more controllable than logs. Pellet boilers can run automatically in much the same way that gas or oil boilers operate. Most pellet and chip burners use automatic fuel feeders which refill them at regular intervals.

Log burning stoves and boilers have to be filled with wood by hand and require considerably more work. You will need a lot of logs to heat a whole house, but they can be cheaper than pellets if you have a good local supply.
