Hi, I am sure there have been plenty of questions about these boliers before. I am hoping there is an expert lurking somewhere around here.
The prroblem is this, hot water;
Turn on tap, bolier fires up perfectly but switches off after about 2 minutes. the pressure gauge is on about 1.5 bar, if I increase the pressure using the filling loop the bolier comes back on, then goes off, a bit more pressure and it comes on again. Obviously I can't keep doing this. Also if I let all the water out of the system via the PRV, then re-fill it, it will then waork again fine for 2 minutes then we are back to sqaure one!
I am thinking DHW flow switch or some kind of heat cut out? which powuld explain why it works if i empty the hot water out and fill it wioth cold?
Any ideas or suggestions would be appreciated.
Thanks.
