Some advice needed please re a 3 year old combi gas boiler. The hot water works but no heating. A gas engineer was already booked to do the annual safety check before the fault developed. He said the boiler is ok with no fault. He said there must be a leak under the floor boards causing hot water to escape and that is why the boiler is contiually running as it thinks a hot tap is open. I have 2 questions please..
1. If there is an underfloor leak shouldn't the boiler pressure guage be dropping? but it is not..it is constant at 1.5 to 2 bar.
2. The engineer left this part behind after he did the safety check (see photo). Is it part of the boiler?..i have pictured it from both sides..many thanks!
