Gledhil boilermate 2000 wiring

[mcheetham]

I have the above boiler, which is working fine but may have been installed incorrectly. Behind the panel is a set of terminals, one with incoming supply (terminals 1,2,3), one to the boiler (4,5,6,7) and and one to the room thermostat (8,9,10,11). Terminals 6 & 7 to the boiler are live (6) and switch live (7). Since it was installed it has been conected to the live terminal, which has been firing up the boiler very often. I recently had it connected to the swich live instead and the boiler now fires less often. Am I right in thinking that when connected to live it was bypassing the sensor and asking for heat all the time? Is it correct now? My builder is in denial and I would like to pursue compensation for the extra gas used? I appreciate anyone who can help, thanks.

ps The boiler doesn't have the switch back up to electricity supply when gas fails.

You are right, but it wouldn't be significantly different as the store tries to maintain 75 degrees the boiler stat is probably set to 80 degrees and the loss across the pipework is probably the difference. Compounded by the fact that the pump which the store controls to pump the primary water from the ch boiler to the store would only be on when store temperature demands it, therefore the boiler would just be sat there maintaining it's own temperature, a very quick burst. I don't predict the saving on gas to be worth the legal costs.

You have it right now, let bygones be bygones look outside the situation and move on to something positive.
