FLOW DESCRIPTION – Domestic hot water. When domestic hot water is used (at a sink or shower etc), water flows out of the top of the tank to the point of use. Cold water replaces the volume of hot water that was used by flowing in at the top of the system, through the heating system, and then into the bottom of the tank. The reasons for this ...

When the water expansion volume (from cold to hot) is more than the remaining air pocket volume, the system pressure will swing rapidly up. It will pass 3 bar and will force open the safety valve. Water will then be dumped outside via the safety pipe. When the system cools, now with less water in it, there will be a rapid downwards swing.
