Firstly, apologies if this has been asked before and/or I'm asking in the
Anyway, I'd be grateful if there's anyone who could tell me why my hot water
temperature is lower when I have my central heating on than if not. I
recently had some rewiring and as far as I can remember before the wiring it
was the same temperature whether I had the heating on or not. However, the
thermostat, boiler, pump etc all appear do the right things at the right
time (ie pump comes on when thermostat tells it to, boiler comes on when
requested, etc). Maybe its to be expected if both are on - the boiler can
only do so much ?
Any help gratefully received.
