Can central heating / gas engineer expert help me with below issue.
During winter time only, I have been having issue with low pressure or pressure dropping with unvented hot water cylinder system.
During summer time there is no usage of central heating so the pressure at unvented system is not losing or low pressure. Pressure at one bar during summer time.
only in winter time, i am having low pressure on unvented system.
During winter time, i run central heating, with in two days, the pressure goes to zero so i have to top-up to 1 and half bar and then pressure goes to zero bar . this is the pressure gauge at unvented hot water cylinder system which shows zero.
I can't see any leak on the ceiling. I wonder whether the water goes back from radiator to hot water cylinder hence the central heating water loses and pressure goes down.
I also get tick tick sound when i start central heating for few mins. I did bleed radiators and gas is released.
