30kW ErP Condensing Combination Boiler

Keston boilers offer a very unique flue system. No expensive flue kits are required, just standard 50mm MuPVC solvent weld waste pipe. This offers cost effective and flexible installations. The boiler can be positioned up to 27 metres away from the flue outlet. 

The Keston Combi boiler is fully modulating, and with its built-in weather compensation, it provides great energy savings, making it ideal for new builds or replacement installations.
