Hello
We have an oil boiler Camry5 which supplies us with hot water and hot water for the rads.
A couple of weeks ago the heating system was running on overdrive, ie. the boiler wouldn't stop heating. The Shell Direct engineer was called in and he replaced the motor in the valve which controls the flow of hot water to the rads.
Every has been running fine since then until last Sunday pm. We noticed the house was cold when we came back from an afternoon out. So we did what we normally do and turn the thermostat up to fire the boiler. Nothing happened, so we sat and waited ... still nothing. Eventually the boiler kicked in and warmed the rads a little then turned off again.
It seems the boiler is warming and heating the rads and when the temperature gets to 16c the boiler shuts off. (I know this because I have a thermometer next to the thermostat). We called the engineer again yesterday and he diagnosed that there was something causing the valve to stick, and that by playing with it the heating had cleared itself - he didn't stick around to find out that the heating shuts down at certain temperature. I found this out again last night!
Got him out again this morning and his diagnosis is that everything was working, and said that the thermostat was broken ... trouble is he doesn't carry them as spares, so I went and bought one and have installed it but we still have the same problem, and I'm still cold!!
Could it be that the boiler has got overheated when the valve got bust and the stat in the boiler is causing the boiler to cut out?
I'd be very grateful for any pointers so that we can try and get Shell pointing in the right direction ...
