Hi all,
New to this forum. Wonder if anyone can help. I have a Worcester Bosch Greenstar 37CDi combi in a 4 bed detached house, fitted with new radiators two and a half years ago. The house is about 30 years old. Since December I'm constantly finding the pressure in the central heating circuit is dropping. I assumed there was a leak, but we've had plumbers round for hours checking under the house (full access under all downstairs floors), under the floorboards and round all the radiators and there's no sign of any water escaping anywhere.
I'm now at the point that if I charge the system up to 1.5 bar, then it needs recharging the next day (i.e. almost 0 bar), and I'm also bleeding loads of air out of the top floor radiators - so there's masses of water getting out somewhere. Because this is a fairly new house we have good access under all floors and we can see that there's no sign of water damage anywhere. We've checked the pressure release valve on the outside of the house isn't letting anything out. My plumbers (who are Worcester Bosch approved fitters) have never seen anything like it and really don't know what the cause is. The only option they can think of is that the heat exchanger is cracked / leaking. Any other suggestions out there?
Thanks for looking
