Why Biomass

Environmentally friendly
Carbon Neutral

Wood pellets are a carbon neutral, renewable biomass energy fuel. The CO2 released when burning wood is re-absorbed by the amount of new trees that are planted.


Approved icon
Quality

The Warmflow biomass boiler has been designed to run on ENplus A1 pellets only, the highest kitemark of quality in the industry. The ENplus quality certification replaces numerous national standards and certifications with one uniform system based on the EN 14961-2 standard for wood pellets.


Thumbs up
Well established

The use of wood pellets for domestic and commercial use has been well established in Europe for the last 25 years.


Savings
Cost effective

Wood pellet boiler equipment is cost-effective to both install and operate and has significantly lower maintenance and capital expenditure costs compared to wood chip boilers. Wood pellets are manufactured from a widely available feedstock typically resulting in less price volatility than with fossil fuels


High efficency
Market leading efficiency

Market leading efficiency at 508% with a number of user friendly options included as standard.
