Combination boilers for smaller homes
Combination boilers offer many room saving and energy economy advantages for the small-scale home. All you require to put in the full central heating system is a combi gas boiler and balanced flue. All that is additionally required to heat your home is some copper pipes and some radiators. Your first thought could be astonished and considered that some pieces had been left out from the system. Isn’t it true that most systems seem to require a feed and expansion tank in the attic, a water pump to move the hot water around and a storage cylinder to keep hot water when not needed.
These component parts are not called for by contemporary combination boilers. You can leave out the hot water storage tank, you do not need a feed and enlargement cylinder up in the attic, the combination boilers also incorporate the other small-scale component parts. So you can see with combination boilers you can save a respectable amount of space within your dwelling house.
Combination boilers are not a new boiler design. They are a very popular boiler in the UK and were first installed in the Continent. By comparison with conventional boilers you will see that there are two major divergences. The central heating hot water circulation system is sealed. Having no open outlets there is no call for for a feed and enlargement cylinder in the loft. Incorporation of a hot water storage vessel within the gas boiler also removes any requirement for the hot water storage tank.
Hot water is created as you need it, switching on a hot water tap will alert the boiler to this need. The hot water is produced by the use of a highly cost-efficient integral heat exchanger. Water from the sealed central heating circuit is heated and is diverted to the hot water heat exchanger heating it up. Fresh cold water from the external 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 instantaneous hot water for the home. The radiators are provided with hot water once the valve is closed.
It is feasible to set up a new boiler in a tiny apartment using combination boilers and not require a large amount of space.
