Pellet Boilers
Wood Pellet Boilers: Clean, Compact & Smart Heating
Wood pellet boilers are among the most advanced biomass heating systems available in the UK. Designed for efficiency and ease of use, they offer a fully automated experience—from fuel delivery to ash compaction.

Intelligent Automation
- Minimal User Interaction: Automated fuel feed and ash removal mean users only need to empty ash two or three times a year.
- Responsive Heating: Pellet boilers adjust combustion in real-time to match building heat demand.
What Are Wood Pellets?
Wood pellets are:
- Uniform and dry, made from compressed sawdust
- Easy to transport and store
- Ideal for controlled, clean combustion
This makes them perfect for smaller heating loads, which is why pellet boilers dominate the domestic biomass market.
Ultra-Clean Combustion
- Electrostatic filters can be added to remove fine particulates
- No visible smoke, even during peak operation
- Meets strict UK air quality standards
