Keston Combi Boilers & Prices

Keston’s combi range of boilers come in either the C30 or the C35 which are available in 30kW and 35 kW power outputs respectively.

Both offer all you would expect from a modern boiler and more, being small enough to fit in most kitchen cupboards as well. Both models also allow you to control the heating and hot water independently, ensuring maximum comfort and efficiency.

And let’s not forget that both these combi boilers connect to the unique Keston twin-flue system, which allows both boilers to be anywhere up to 27 metres from the flue outlet – this offers a degree of flexibility not seen in a lot of other boiler manufacturers.

Comparing Costs: Keston Combi Boiler

Cost alone should not be your primary driving factor when in the market for a new boiler. For example, if you just go for the cheapest new boiler you can find then chances are it wont be up for the job. If you live in a 4 bedroom house with 10+ radiators and 3 bathrooms, then a 30 kW combi boiler would not be the right choice as it couldn’t handle the load.

This is where the experience of a Gas Safe heating engineer really comes into play, as they can advise you on what your new boiler needs to look like based on your unique requirements. Get quotes for a new Keston boiler.
