Keston 45 Heat Regular Boiler ErP 355003

45kW ErP Condensing Regular Open Vent 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 Heat is a lightweight wall hung regular boiler. The lightweight design is supported through quality build and aesthetics that allow for the boiler to be installed either on the wall or into a prefabricated floor mounted frame including back-to-back options.

The range provides high efficiencies for low running costs with up to 110% part load and seasonal efficiency (ref Building Regs Part L2) up to 97%. The range also provides low NOx emissions at Class 5 and at less than 40mg/kWh achieve maximum points
under BREEAM schemes.
