Keston C35 35kW Combi Boiler

The Keston C35 combi boiler combines both a water heater and central heating in one unit, removing the need for any additional hot or cold water tanks.

Combi boilers are great space savers and are loved by many UK households thanks to their compact size.

The C35 combi boiler has an efficiency rating of 89.6% and an ErP A-rating for central heating and hot water, meaning that depending on the efficiency of your current boiler, this combi boiler could potentially help you lower your energy bills.

With an output of 25.6kW for central heating and 35.3kW for hot water, the C35 combi boiler is ideal for homes with 15 radiators and up to 2 bathrooms. Smaller homes may not require this demand for central heating and hot water. In this case, the C30 is also available with the same output for central heating but an output of 30.3kW for hot water. On the other hand, for larger-sized properties, you might want to consider Keston Heat 45kW or 55kW regular gas boilers. 

Keston boilers are typically used in compact spaces such as smaller flats/properties in locations such as London. This is because Keston boilers offer a twin flue system which makes every job easier. To give you maximum flue flexibility, the flue can run vertically or horizontally from an elevation of 1.5 degrees and the flue can be extended up to 27 metres from the boiler.

This allows for hassle-free and easy installation and means that your new boiler can be installed in the most practical and convenient space in your home.
