Domestic Gas Boilers

What are the different types of domestic gas boilers?

System Boilers

A system boiler heats your central heating system directly and produces hot water for your cylinder.

A system boiler, just like a regular (conventional) boiler works on the principle of stored hot water. However, a system boiler differs from a regular boiler in some important respects.

Firstly, many of the major individual components of the heating and hot water system are built into a system boiler, which means that installation is quicker, neater, easier and more efficient.

Secondly, the hot water is pumped from the system boiler through the heating system to the radiators and hot water cylinder, resulting in a fast response and more economical running costs. The system boiler removes the need for a feed and expansion cistern.

Combi Boilers

The highly efficient, condensing combi or combination boiler is an ingenious space-saving device. The biggest difference between a combi and other types of boilers is its ability to eliminate the need to store hot water.

It is both a high efficiency water heater and central heating boiler combined. Designed in one compact unit, it would ideally be fitted in the kitchen or utility room which offers enormous space saving benefits due to the fact that a hot water storage cylinder is not required.

The combi delivers significant savings and hot water is delivered through your taps or shower at mains pressure. So you can enjoy can enjoy a powerful shower without the need for a pump. As there are no tanks in the roof space a lot less pipework is required and therefore reduces the overall installation time.
