Where does hot water go in a direct central heating system?
In older houses, with a direct system, the hot water may be stored in a square galvanised tank. The principle is the same. Using the diagram above as a reference, another cold water pipe runs from the base of the cylinder to the boiler. The boiler heats the water and returns it to the tank higher up.
What do you need to know about mains pressure hot water systems?
In an unvented system you will be storing a large volume of hot water under pressure. For reasons of safety these systems must be installed by qualified technicians with relevant experience, CITB training and G3 certification.
