Central Heating Control

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.

gav8553 brought next idea :

Of course it will affect the stat and the temperature it 'sees'.

You have more or less confirmed that by suggesting that the boiler is not firing, but you are still cold. If it is a wireless one, then it should be fairly easy to try various alternative positions for the stat, to see where works best.

could be. Just see if it is calling forheat.

get a radio stat if you need to move it.

Being a digital control, does it have a display which shows the current temperature and target temperature (maybe by pressing a button)? If so, you should be able to see whether the displayed temperature is being biased by the nearby UFH. There may well be other reasons why the heating isn't starting but if it *is* due to bias, the obvious solutions are:

  1. Bias the stat to lie about the temperature it sees (some have an offset facility for this purpose), OR
  2. Move the stat somewhere where there won't be a bias, OR
  3. Replace the stat with a wireless stat, and experiment to find the best position
