Can I have a Pressurised hot water system?
However, if you require pressurised hot water because you plan on installing a power shower, you can install a pressurised hot water cylinder but would require a pressure reducing valve (PRV) to relieve pressure when water is circulating through the pipes.
What pressure should a Pressurised hot water system be?
1.5 bar
Most manufacturers recommend a minimum supply pressure of 1.5 bar, and 20 l/m flow rate.
Is central heating connected to mains water?
The water to your radiators is the central heating system. Although both share some of the main components in the heating system, the water and pipework is not mixed. Different ways of heating the domestic hot water need to be understood in order for the home owner to identify theirs and effect any maintenance needed.
Can a pressurised hot water tank be used for cold water?
With an unvented pressurised cylinder system you can say goodbye to low pressure outlets, bad flow rates and that big bulky cold water storage tank in your loft – Instead say hello to a highly efficient sealed hot water storage cylinder which is fed directly by the cold water mains.
How does a mains pressure hot water system work?
Mains pressure water system Flow of water round a instant heating combination boiler system In a mains pressure hot water system there is no intermediate cold water storage tank. Cold water is fed directly from the mains to the points of use. The rising main is connected directly to the calorifier, water heater or plate heat exchanger.
Where does the cold water go in a hot water system?
In a mains pressure hot water system there is no intermediate cold water storage tank. Cold water is fed directly from the mains to the points of use. The rising main is connected directly to the calorifier, water heater or plate heat exchanger.
What are the disadvantages of a mains pressure hot water system?
Disadvantages of a mains pressure hot water system To every action there is an equal and opposite reaction. In other words there are pro’s and con’s. The pro’s have been examined above, but then there are other considerations. Yes. Mains pressure systems can be expensive to install.

How are hot and cold water systems connected?
Cold water is fed directly from the mains to the points of use. The rising main is connected directly to the calorifier, water heater or plate heat exchanger. Since the water in the system will expand due to heating, an expansion vessel and a safety temperature and pressure relief valve are required.
