| Motorised Valve Controlling Hot Water |
The hot water cylinder should be supplied with heating water from the boiler via a separate circuit from the space heating circuits.
Two aspects of a hot water cylinder that should be controlled are the on/off times and the temperature at which the hot water in the cylinder is stored.
Motorised valve
The most common method of ensuring that the hot water cylinder can be heated at times when space heating is not required is to install a motorised valve on the space heating circuit so that it can be isolated from the cylinder heating circuit.
An alternative could be to provide individual pumps for the hot water cylinder and heating circuits.
