If you are about to install a new heating boiler you should consider a combi gas boiler if you have a shortage of storage space. With just a combination gas boiler and balanced flue you have all the pieces 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 heat your room you will be complete. You might ask whether we had overlooked some component parts out of this statement. What about the central heating pump, the hot water storage cylinder and the feed and expansion cylinder.
It may surprise you to learn that a combination boiler does not need these pieces. You do not need to purchase a hot water storage tank, there is no call for for an attic based feed and expansion tank, the combi gas boiler houses the other parts inside its casing. As a consequence you can save a significant amount of space in your dwelling house.
Whilst you might think all this is new actually combi gas boilers have been set up for a number of years. They are a very popular gas boiler in the UK and were first installed in the Continent. There are two main differences to be highlighted when compared with traditional heating boilers. The first point to highlight is that the circulating hot water for the central heating is within a fully sealed system. This means that there is no demand for a feed and enlargement cylinder in the loft. A second benefit is getting rid of the need for the hot water storage tank as the boiler stocks its own hot water.
As hot water is required it is produced right away by the heating boiler, turning on a hot water tap will alert the heating boiler to this need. And efficient internal heat exchanger enables the gas boiler to quickly heat and cold water. Hot water in the central heating system is used to instantly heat the heat exchanger. In this way fresh mains cold water is rapidly heated before reaching the hot water valve.
Automated priority is rendered to the need for hot water over water being provided to the radiators to heat up the home. When the valve is shut again the central heating water is returned to its regular circuit.
This might give you food for thought and the impulse to look at a combi heating boiler as your next new heating boiler.
