Hi all looking for some help here before I lose the will to live!!! Long story so I'll keep it as short as possible & to the point if I can.. ok..I have a Grant 70/90 series outdoor boiler. I had a fire in it 2 weeks ago,it melted the thermostat & wireing. I have had a new set of baffles installed (as the old ones were in bits) & the guy said that was my problem... also installed a new thermostat & time clock.& insulated it.He said the burner was fine(I replaced it 2years ago) Pump is fine too......he got it going & it worked fine for one day...now its gone again. I had it set on timer to come on this morning at 7am...which it did,but it went off again as the rads wernt hot only warm...I checked the clock & there is no indicator light on.....no fuses blown,took front cover off & discovered thermostat is slightly melted??? boiler is totally dead....all electrics in the house are fine....so can anyone tell me what to look for? The guy that fixed it is unavailable for the next two weeks...I would be grateful for any help please.
