The pressure in my central heating system drops very fast (at the rate of 1 bar every 3 or 4 days), which requires me to top it up. The rate of loss seems to be higher when the heating is on for longer periods of time. I have checked my installation and cannot seem to locate a leak on pipes, rads or valves. And I suspect that considering the size of the leak I should notice it over time. I have also checked the pressure release valve and I believe that it is not leaking
Could the loss of pressure result from the boiler?
I have a 10 year old combi boiler (Vaillant).
