Salvage room with a combination gas boiler
If you are about to install a new heating boiler you should consider a combi boiler if you have a shortage of room. A combi boiler and balanced flue contain all the elements you need to set up a full central heating system. If your heating engineer adds in a number of radiators and the appropriate copper piping you have absolutely everything to warm your dwelling house. Your first reaction maybe that we had forgotten some parts. The hot water storage cylinder, the feed and expansion cylinder ordinarily put in the loft, the central heating pump and other component component parts that central heating and hot water systems seem to need.
Surprisingly a combi heating boiler does not require any of these pieces. With a combi you can dispense with the hot water storage tank, the feed and enlargement cylinder can be left out of the loft, and the other smaller elements are already built into the gas boiler. So you can see with a combination heating boiler you can save a sizeable amount of room within your home.
Combi heating boilers are not a new gas boiler design. Whilst they were first set up in Europe they are now a very popular boiler for fitting in the UK. By comparing with traditional boilers you will see that there are two major divergences. The first is that hot water circulates around a sealed system when warming the central heating. This gets rid of any demand for a feed and expansion cylinder in the loft. Additional room is saved by the boiler integrating its own hot water storage vessel removing the requirement for the hot water storage cylinder.
The boiler produces hot water immediately as it is required, turning on a hot water valve will alert the gas boiler to this need. An cost-effective integral heat exchanger is used to rapidly 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 supply to the radiators is a lower importance than the output of instantaneous hot water for the household. Once the tap is closed and the need for hot water is eliminated the system will return to providing hot water to the radiators.
This might give you food for thought and the impetus to consider a combi heating boiler as your next new boiler.
