I have had my house for about a year now, i noticed my central heating pressure gauge was 0.5 bar the other day when the heating was off (not had the central heating on since) when i know it was 1.8 bar at some point last year. So i topped it up to about 1.9bar. not used central heating since and today i look and it is 1.3-1.4 bar about 5 days later, is this normal? if im not using the central heating at all and i top it up and then the pressure falls does it mean there is a leak in the house??
its one of these dual pressure systems with the boiler in the kitchin and a filling loop on the 3rd floor with the rest of the water system, dont think it is a combi bolier though.... the heat is transferred somehow to the central heating in the airing cuboard on the 3rd floor
