A high pressure mains system comprises of an unvented cylinder with no header tank in the roof. In this system both the hot and cold water are supplied at mains pressure. The Items available to choose from that work with this system are recommended to have a bar pressure that is; ≤ 3.0 Bar.
A gravity system with a pump is like a low pressure gravity system with a header tank and a copper cylinder, except that there is a pump boosting the pressure of the hot and cold water which operates in demand and converts this system to high pressure. The Items available to choose from that work with this system are recommended to have a bar pressure that is; ≤ 3.0 Bar.
