Keston regular boilers

If you already have a regular boiler installed in your home but need to replace it, it's usually cheapest and easiest to fit a new regular boiler.

If you have multiple bathrooms and a high demand for hot water, a regular boiler is the best choice. The Keston heat models are available in either 45kW or 55kW outputs and are ideal for large homes with several bedrooms and more than one bathroom.

Keston system boilers

There are lots of advantages in fitting a system boiler. They are able to supply hot water to multiple outlets at the same time without losing pressure, and unlike a regular boiler they don’t need a supply of cold water from a storage tank.

The Keston S30 is a 30kW boiler, which is more than capable of providing hot water to multiple bathrooms and heating up to 15 radiators.
