Combi gas boilers are advocated for tiny houses
Combination heating boiler systems offer many space saving and gas economy advantages for the small-scale house. You only need a combination gas boiler and balanced flue to set up a full central heating system without any other parts. To complete the heating you just need radiators, the necessary fittings and an amount of copper piping. You could be surprised by this and ask whether we had left out some components. What about the water pump, the hot water storage tank and the feed and expansion tank.
These components are not required by a modern-day combi heating boiler. You do not need to buy a hot water storage cylinder, you do not require a feed and enlargement cylinder up in the attic, the combination boiler also incorporates the other tiny component parts. This withdraws the requirement for a lot of elements, which take up a lot of room in your home.
Whilst you might reckon all this is new actually combination boilers have been put in for some years. They have a longer history in Europe but have now become the most popular heating boiler in the United Kingdom. By comparing with conventional boilers you will see that there are two main divergences. The central heating hot water circulation system is sealed. The feed and expansion tank destined for the loft can now be dispensed with. A second advantage is withdrawing the requirement for the hot water storage tank as the boiler stocks its own hot water.
As hot water is called for it is produced instantly by the gas boiler, turning on a hot water valve will flag the need to the boiler. Cold water is rapidly heated up by the use of an economical heat exchanger. The heat exchanger is heated by clever use of the existing hot water in the central heating system. Fresh cold water from the outside mains passes through this heat exchanger where it is heated before it reaches the hot water valve.
Automatic priority is established to the demand for hot water over water being rendered to the radiators to heat up the dwelling house. When the tap is closed again the central heating water is returned to its regular circuit.
This might give you food for thought and the impulse to consider a combination gas boiler as your next new boiler.
