Economise on storage with a combination gas boiler
If you are about to fit a new gas boiler you should study a combi gas boiler if you have a shortage of storage space. With just a combination heating boiler and balanced flue you have all the parts you require to fit a full central heating system. Include radiators and copper piping and you are then able to heat your home. Your first thought could be surprised and considered that some component parts had been missed out from the system. Isn’t it true that most systems seem to need a feed and expansion tank in the loft, a water pump to transfer the hot water around and a storage cylinder to keep hot water when not called for.
These component parts are not required by a modern-day combi boiler. The hot water storage tank can be omitted from your system, you do not require a feed and expansion cylinder up in the loft, the other smaller components we have brought up are actually built into the combi boiler. As a result you can save a considerable amount of space in your dwelling house.
Do not think that all this is new as combination gas boilers have been installed for a while now. The combination has been more popular in Europe than in the U.K., but is now being fitted more frequently as an alternative to the conventional wall mounted heating boiler. By comparison with traditional gas boilers you will see that there are two main differences. A fully sealed system contains the circulating hot water for the central heating. The feed and enlargement tank destined for the loft can now be dispensed with. Extra room is saved by the boiler incorporating its own hot water storage cylinder removing the requirement for the hot water storage cylinder.
The heating boiler produces hot water immediately as it is needed, this is signalled when you turn on a valve. An efficient internal heat exchanger is used to quickly heat up cold water. The heat exchanger is heated by clever use of the existing hot water in the central heating system. On the other side of the heat exchanger cold mains water is heated before finishing its journey to the hot water tap.
Hot water production is prioritised ahead of the passage of hot water to the radiators. The radiators are supplied with hot water once the tap is closed.
If you do have a storage space issue in your home you should give critical consideration to putting in a combination heating boiler when you next replace your boiler.
