I'm having difficulty getting my (gas) central heating to start in the morning. The digital control is situated on an internal wall (engineering brick) which has underfloor heating (v. efficient!) on the other side. Is it likely that the heat from the underfloor heating will affect the heating control by heating up the wall to a temperature above that set, so the heating does not come on.
If so, would moving the control to a different wall, away from the heat source be a good idea? Or is there another solution, apart from jacking the temperature up to uncomfortable levels?
Grateful for any suggestions.
NB Boiler is new and working fine.
