Conventional Boilers

Conventional boiler systems heat the water which is pumped round through the radiators, hot water for washing is heated in a tank, often in the airing cupboard, by a feed from the radiator system, this tank is refilled from a large cold water tank, usually in the loft. A smaller tank, again, usually in the loft, "tops up" the radiator system as needed.

This system allows large amounts of hot water to be drawn off as fast as the taps will allow. However, as the hot water is taken the tank is refilled by cold water and it will be some time, as much as 30 minutes, before it is heated to a useable temperature.

Combination Boilers

Combination boiler systems heat the water which is pumped round through the radiators in a similar way to conventional boilers, the main difference is that hot water for washing is heated on demand and not stored. This means that there is no need for a hot water tank, and, because the cold water taps are fed directly from the mains water supply, there is no need for the large cold water tank in the loft either.

These systems heat water as required and are very efficient. They produce a continuous flow of hot water, the flow rate is sufficient to run a shower, fill a bath or washing machine etc. , however multiple taps running simultaneously will share this flow between them.

We fit and maintain systems using conventional and combination boilers, both in gas and oil burning types, the model that suits you best will depend on many factors.

We use boilers from Worcester, Glow-Worm, Grant and Vaillant, over the the years these have proved to be well made and reliable.
