I have had a pressurised hot water cylinder for many years, and when hot, the pressure on the hot taps was crazy. You could be in the shower for quite a long time before hot and cold pressures equalised.
I am now at a new house looking to install at a new hot water cylinder system, and looking at the Gledhill installation manual. It shows an expansion vessel on the cold feed, but with a non return valve before it, so that the excess pressure of the expansion vessel remains inside the cylinder. This non return valve is there to stop back flow of hot water towards the cold water taps.
But that also means that again I will have a system where the hot and cold taps will be greatly unbalanced.
Am I missing something?
