Use a combination in a small household
If you have a storage space problem in your household you should study putting in a combination boiler. It is possible to fit a complete central heating and hot water system by buying only a gas powered combi gas boiler with a balanced flue. Add in radiators and copper pipes and you are then able to warm your home. You could be surprised by this and ask whether we had left out some components. Central heating systems seem to need a hot water tank to store water, a feed and expansion tank in the loft and a water pump to move everything around.
Surprisingly a combi boiler does not require any of these pieces. The hot water storage tank can be excluded from your system, there is no need for an loft based feed and enlargement cylinder, and the other tiny components are already built into the boiler. Adopting this system means you can save a considerable amount of room.
Do not think that all this is new as combi heating boilers have been fitted for a while now. They have a longer history in Europe but have now become the most popular boiler in the UK. It is has two main deviations with the system and normal type of boilers. The first point to highlight is that the circulating hot water for the central heating is within a fully sealed system. This takes away any requirement for a feed and expansion cylinder in the attic. Additional room is saved by the boiler incorporating its own hot water storage vessel removing the requirement for the hot water storage cylinder.
Home hot water is produced on demand, the heating boiler is aware of this when you switch on a hot water valve. The gas boiler can rapidly heat cold water by using an internal heat exchanger. Hot water circulating in the heating system is diverted to the heat exchanger. Fresh cold water from the outside mains passes through this heat exchanger where it is heated before it reaches the hot water tap.
Automated priority is given to the requirement for hot water over water being rendered to the radiators to heat up the house. When the tap is closed again the central heating water is returned to its normal circuit.
So in summary and combi boiler can save you a considerable amount of storage space in your house.
