If you are about to install a new gas boiler you should study a combi heating boiler if you have a shortage of storage space. All you need to fit the full central heating system is a combi heating boiler and balanced flue. With the inclusion of copper piping to transfer the hot water to the radiators to warm your house you will be finished. You could be surprised by this and ask whether we had forgotten about some parts. Central heating systems seem to need a hot water cylinder to store water, a feed and expansion cylinder in the loft and a water pump to move everything around.
These component parts are not required by a modern combination gas boiler. You will have no requirement for a hot water storage tank, the feed and expansion tank can be left out of the attic, the combi gas boiler also incorporates the other petite components. The consequence is that a lot of space is saved inside your dwelling house.
Combination heating boilers have been fitted for a while. Whilst they were first set up in Europe they are now a very popular gas boiler for fitting in the UK. It is has two main divergences with the system and normal type of heating boilers. On the central heating side you still have a fully pumped system but all the heated water which circles around is sealed in. This means that there is no need for a feed and enlargement cylinder in the loft. A second gain is getting rid of the need for the hot water storage cylinder as the boiler stocks its own hot water.
Hot water is developed as you need it, the heating boiler is aware of this when you switch on a hot water valve. The gas boiler can quickly heat cold water by using an integral 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 valve.
Automated priority is given to the demand for hot water over water being provided to the radiators to heat up the home. The moment the valve is closed the combi gas boiler will return to rendering hot water to the radiators.
So in conclusion and combi gas boiler can save you a considerable amount of space in your house.
