Gas back boilers

It is not uncommon to find back boilers in older housing stock, these are are normally obscured at the back of a chimney, with a fire in front to hide them.

Modern Combination gas boilers

Combi gas fired boilers have become the best selling boiler type for gas central heating in the UK.

Look out for someone turning on all the hot water taps in your household whilst you are running a hot bath as it could temporarily turn cold.

Unvented system gas fired boilers

central heating heating boilers use a water cylinder to store hot water. This will demand space in your home. Building the other central heating system constituents into the gas fired boiler this means that installation is less complex and lower-priced.

You can now run several hot water taps concurrently as they are provided from the hot water tank. You can get a good internal water pressure from a central heating system heating boiler by installing the hot water cylinder high in the house.

Open vent system heating boilers

The most common household central heating system is an open vent heating boiler. They come with two water cylinders to be installed in the loft., a lot of valuable storage space is needed as the hot water storage is also required in the airing closet.

One of the loft cylinders feeds the hot water storage cylinder with water from the mains.

The 2nd is called the feed and expansion and this enables the water in your central heating system to expand and contract. The only limit on hot water supply now is the capacity of the hot water cylinder which will take a while to heat up fully.
