Combi boilers are commended for small homes
If you have a small-scale household a combination gas boiler offers room saving opportunities to you. With just a combination gas boiler and balanced flue you have all the pieces you require to install a full central heating system. With the inclusion of copper pipes to transfer the hot water to the radiators to warm your room you will be complete. You could be astounded by this and ask whether we had forgotten about some parts. Isn’t it true that most systems seem to require a feed and enlargement tank in the attic, a water pump to transfer the hot water around and a storage cylinder to keep hot water when not called for.
It may shock you to learn that a combination heating boiler does not need these component parts. You can leave out the hot water storage cylinder, there is no requirement for an loft based feed and enlargement tank, the combi boiler also incorporates the other tiny component parts. This removes the call for for a set of components, which take up a lot of room in your household.
Combination boilers are not a new heating boiler design. The combi has been more popular in Europe than in the U.K., but is now being installed more frequently as an alternative to the traditional wall mounted gas boiler. By comparison with traditional boilers you will see that there are two major deviations. The first is that hot water circulates around a sealed system when heating the central heating. The feed and expansion tank destined for the loft can now be dispensed with. Inclusion of a hot water storage vessel within the gas boiler also removes any need for the hot water storage tank.
Domestic hot water is developed as required, switching on a hot water signals this requirement to the heating boiler. Cold water is rapidly heated up by the use of an cost-effective heat exchanger. The heat exchanger is heated by clever use of the existing hot water in the central heating system. Fresh cold water from the outside mains passes through this heat exchanger where it is heated before it reaches the hot water tap.
Hot water provision to the radiators is a lower priority than the production of instant hot water for the home. The radiators are furnished with hot water once the valve is closed.
As a consequence you should give critical consideration to fitting a combination gas boiler for your next renewal heating boiler.
