I have a sealed c/h system with a Worcester Bosch Greenstar 24Ri boiler. But I lose all pressure every day, yes within 24 hrs or probably abour 5 hrs of heating and 1.5 hrs of hot water!!
Cant find a leak anywhere, and can see about 90% of all pipework.
Expansion vessel pressure is good.
Not coming from overflow, so pressure isnt building up and releasing water.
Put valves all over the place, so isolated upstairs, downstairs and each rad - nothing.
Seen a lot of posts on various forums about people moaning about losing pressure over a week or 2.. if only!!!
Latest idea has been the condensate pipe - so cut it and put a bucket under. After 1 hr of hot water and 2 hrs of c/h theres just over 300ml of water in the bucket.
Is this normal!? Seems a lot to me, but I cant find info on how much should come out.
Can anyone help???
Please - to make matters worse the vessel and filling loop are in the loft, so I'm getting fed up with going up at 5 every morning to let mains water in (about 5-10 seconds' worth) to let the system fill then heat!!!
