Smaller houses should look at combi heating boilers
Combi boiler systems offer many storage space saving and energy economy benefits for the small household. With just a combination boiler and balanced flue you have all the components you require to put in a full central heating system. With the inclusion of copper pipe to transfer the hot water to the radiators to warm your house 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 loft, a water pump to move the hot water around and a storage tank to keep hot water when not required.
If you have a modern-day combi heating boiler it will not require any of these incremental component parts. You do not need to buy a hot water storage tank, you do not require a feed and expansion cylinder up in the attic, the combination boiler contains the other component parts inside its casing. As a result you can save a significant amount of room in your house.
Whilst you might consider all this is new actually combination heating boilers have been put in for some years. Whilst they were first installed in the Continent they are now a very popular heating boiler for fitting in the United Kingdom. By comparison with traditional heating boilers you will see that there are two main differences. The central heating hot water circulation system is sealed. The benefit of this is that there is no requirement to fit a feed and enlargement cylinder in the loft. The boiler itself contains a large capacity enlargement cylinder but again this is part of the sealed unit.
Hot water is developed as you require it, the boiler is aware of this when you turn on a hot water valve. The boiler can quickly heat cold water by using an integral heat exchanger. The heat exchanger is heated by channeling circulating hot water from the central heating system. In this way new mains cold water is rapidly heated before reaching the hot water valve.
Hot water supply to the radiators is a lower importance than the output of instantaneous hot water for the dwelling house. The instant the hot water tap is closed the combination heating boiler system will again start offering hot water to the radiators.
As a result you should give serious thought to installing a combi boiler for your next renewal heating boiler.
