while renovating a 400 year old property, I opted for a combi and underfloor heating. Builders son ( who said he was experienced) did this. Ive since learned its not been fitted well, and ive had many probs.(hes since disappeared)had lots of plumbers, but they havent a clue.I think its all about pressure etc, where can i get a plumber that knows, without paying a fortune? there doesnt seem to be any around locally. It seems the water is hot, but not going through the system. Now my domestic water is running hot.. but turning to cold. He didnt fit any zone thermostats at all.. ok.. I now realise , i did wrong giving him the job ! but how can i make a bad job good ? He didnt even leave details of the system

It's unfortunate, but now you are likely to need an expert. This someone will have to follow the existing system through and correct it. For this they will need a total understanding of such systems.
The other way is to have the system removed and rebuilt from the start.
Either way it is not likely to be cheap.
Ensure any fitters you use are CORGI registered.
