Greetings all.

Called my plumber out 2 weeks ago to fix my boiler and a radiator that was cold. He couldnt find anything wrong with the boiler so just did a service on it as best he could. He also fixed the radiator.

The fault I have, which is kind of intermittent, I'd say 80% it doesnt run properly, 20% it does, is: The hot water doesnt get hot enough, after a day or two it's tepid at best. Also the boiler cuts out before the house is up to to the 21° I set the thermostat to. I have to keep lowering the thermostat down to 14 or so then back up to 21 to trigger it into firing the boiler again.

My next step I think is to contact glowworm and get them to send an engineer out. They have quoted a fixed price of £118 plus £60 for one spare part, £90 for two.

Before I do that I just wondered if anyone thought it might be worth me just ordering and trying a new thermistor first? Pretty sure I changed one on a 40ff I had at my previous property so it cant be that tricky.

Any advice appreciated.

Thanks

I did, last week. Anyway booked glowworm now. This morning hot water working perfectly. Should go wrong again before he visits next week though, hate intermittent faults.
