Hi
Just looking for some advice please.
I have the above make of central heating boiler.
When the hot water is called for sometimes it produces hot sometimes it doesn't.
The system is on contract with british gas. I had this same problem about 18 months ago and BG were called out. The engineer said that there was nothing wrong with the boiler and that the fault was more likely a faulty mixer tap and that cold water was getting into the hot water circuit. Literally over night the fault cleared and has been fine ever since.
The fault has just returned and I feel reluctant to call BG out again (or should i?). I just wondered if any experienced boiler engineers had any thoughts (I'm an electrician by trade so no boiler experience as such).
I understand that I could isolate the cold water/mixer valves circuit to prove it, but it is a bit of a pain getting under the floor.
I read somewhere on a forum that the Vailant Diverter valve, microswitch or diaphragm can cause such a fault?
Would appreciate any ideas??
Thanks
Peter
