I recently replaced a simple analogue 3 wire thermostat with a Horstmann Centaurstat 7 to enable us to prevent the house getting too cold at night and also to have the heating coming on at different times on different days as the original controller didn't allow this. The new thermostat was fitted in the same position as the original.
The new thermostat is working correctly. However, it has a current temperature readout on the display and we've noticed that the temperature reading doesn't change when the house feels cold and we'd expect the heating to come on. Obviously because it's new we watch this like a hawk as we didn't have this feature before!
I've subsequently noticed that there are some central heating pipes buried under the tile floor that pass very close to the wall where the thermostat is mounted. When the heating has been on for a while the floor heats up and there is an underfloor heating effect in the localised area of the pipes. The hall is quite large but there is approximately 2 square meters of floor that gets warm which is pretty much directly under the thermostat.
Would i be right in thinking that this will be reducing the sensitivity of the thermostat as the floor acts as a heatsink and prevents the thermostat from seeing the true air temperature? Presumably when the heating is coming on from cold it won't be an issue as the floor will not be radiating, but once the section of floor with pipes underneath it has warmed up this will be radiating heat and therefore stopping the thermostat from seeing the true temperature in the hall.
Comments appreciated.
