Pellet heating for greater capacity needs
The Kepo AC 20 pellet boiler delivers a thermal output of 20 kW, making it ideal for medium-sized homes, commercial premises and buildings with higher heat demands. It combines eco-friendly heating from renewable wood pellets with advanced combustion technology and consistent performance.
Benefits for both installers and end users
Automatic cleaning of the burner and heat exchanger keeps efficiency levels high while minimising maintenance. The AC 20’s compact footprint and standard connections make installation straightforward in both new and retrofit projects. Installers benefit from excellent component accessibility, which simplifies servicing.
Advanced combustion control
The intelligent controller continuously adjusts pellet feed and air supply to match the actual heating demand. This ensures stable heat output, reduced fuel consumption and extended boiler life – all while maintaining optimal comfort.
Versatile integration options
The AC 20 can be combined with high-capacity buffer tanks, underfloor heating, radiators and hot water modules. It also supports integration into hybrid heating configurations with solar thermal systems or heat pumps. With the optional BigTank pellet storage (225 kg), refill intervals are significantly extended, which is particularly beneficial for larger systems.
Easy operation and comfort
The 4.3” colour touchscreen makes adjusting temperatures and programming schedules straightforward. With the optional WiFi module, remote control from a smartphone or tablet is possible. Its quiet operation means it can be installed near living or working areas without disruption.
