Wood Pellet Boilers
An automatically-fed biomass boiler that heats your whole home from compressed wood pellets — lower bills, a smaller carbon footprint, and full compatibility with your existing radiators or underfloor heating.
What is a wood pellet boiler?
A wood pellet boiler is an efficient, environmentally friendly heating system fuelled by compressed biomass rather than oil or gas. The pellets themselves are typically made from compacted sawdust and other recyclable wood material — a dry, dense fuel that burns cleanly and produces more usable heat than loose wood or coal.
Key benefits
- Reduced heating bills and a superior Building Energy Rating (BER)
- High energy efficiency with fine control over output
- A smaller carbon footprint than oil or gas heating
- Protection from volatile oil and gas prices
- Less ash than wood or coal, and less creosote — a flammable residue linked to chimney fires
- Minimal smoke spread, as the flame is contained inside a sealed heat box
From bulk store to warm room
- Wood pellets are delivered and pumped into a bulk pellet store on your property.
- An internal vacuum feed system automatically transfers pellets from the store to the boiler through a feed hose.
- The pellets are burned in small, metered amounts whenever your time clock or thermostat calls for heat.
- The boiler's heat exchanger transfers that heat from the burning grate into your central heating system.
- The heat exchanger self-cleans every day, keeping the boiler running at high efficiency without manual intervention.
- Once your rooms reach the temperature you've set, the boiler output drops back and the system shuts down until heat is needed again.
Works with the heating system you already have
Wood pellet boilers are fully compatible with standard water heating, radiators and underfloor heating — so switching to biomass doesn't mean replacing the rest of your system.
