Combination heating boiler benefits
Combination heating boiler benefits
If you are about to set up a new boiler you should consider a combination heating boiler if you have a shortage of space. With just a combination boiler and balanced flue you have all the components you require to set up a full central heating system. If your plumber adds in some radiators and the appropriate copper piping you have absolutely everything to warm your house. Many people might ask whether some parts had been overlooked from this system. Central heating systems seem to require a hot water tank to store water, a feed and expansion cylinder in the attic and a water pump to move everything around.
If you have a modern combi boiler it will not require any of these extra component parts. You do not need to purchase a hot water storage cylinder, there is no requirement for an loft based feed and enlargement tank, the other petite component parts we have named are actually built into the combination boiler. This takes away the need for a set of components, which take up a lot of room in your home.
The combination gas boiler is not new. The combination 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 heating boiler. By comparison with conventional boilers you will see that there are two main divergences. On the central heating side you still have a fully pumped system but all the heated water which circulates around is sealed in. The benefit of this is that there is no need to fit a feed and expansion cylinder in the attic. The hot water storage tank can also be given up as the gas boiler will have its own hot water storage vessel.
As hot water is called for it is produced right away by the boiler, turning on a hot water tap will flag the need to the heating boiler. The gas boiler can quickly heat cold water by using an integral heat exchanger. The heat exchanger is heated by diverting circulating hot water from the central heating system. This allows cold mains water to be quickly heated before leaving the hot water tap.
Hot water output is prioritised ahead of the transit of hot water to the radiators. The radiators are furnished with hot water once the valve is closed.
As a result you should give serious thought to putting in a combi heating boiler for your next renewal boiler.
