Combination gas boilers for small-scale homes
Combi gas boiler systems offer many space saving and gas cost-efficiency benefits for the petite dwelling house. All you need to put in the full central heating system is a combination gas boiler and balanced flue. With the addition of copper pipe to transfer the hot water to the radiators to warm your room you will be complete. Your first reaction maybe that we had forgotten some parts. Isn’t it true that most systems seem to need a feed and expansion cylinder in the attic, a water pump to transfer the hot water around and a storage tank to keep hot water when not called for.
If you have a contemporary combination heating boiler it will not require any of these extra pieces. You will have no call for for a hot water storage tank, you do not require a feed and expansion cylinder up in the loft, the combination gas boiler also incorporates the other small elements. As a consequence you can save a considerable amount of room in your dwelling house.
Combi gas boilers are not a new boiler design. Whilst they were first set up in the Continent they are now a very popular boiler for installation in the UK. It is has two major divergences with the system and typical type of boilers. A fully sealed system contains the circulating hot water for the central heating. The advantage of this is that there is no need to fit a feed and enlargement cylinder in the loft. The boiler itself incorporates a large capacity enlargement tank but again this is part of the sealed unit.
Hot water is produced as you need it, switching on a hot water valve will signal the need to the heating boiler. The hot water is produced by the use of a highly cost-efficient internal heat exchanger. Water from the sealed central heating circuit is heated and is diverted to the hot water heat exchanger heating it up. On the other side of the heat exchanger cold mains water is heated before completing its journey to the hot water tap.
The boiler design gives priority to getting instantaneous hot water. Once the valve is shut and the need for hot water is eliminated the system will return to providing hot water to the radiators.
If you do have a storage space problem in your house you should give critical thought to fitting a combi heating boiler when you next replace your boiler.
