Underfloor heating probe

[Mike Chapman]

Hi, underfloor heating not working think it's the probe which I can't access, is there an external probe I can use, if so how. Cheers

The probe should be encased in a conduit down the wall and into the floor so that you can pull it through from the thermostat and replace it if it goes wrong. If it hasn't been channeled correctly, then you are going to struggle putting the new one in without lifting the tiles/flooring. Having an external probe, I can't imagine it would read the temps accurately.

You can set most thermostats to read the air temp instead of the floor, if its working when you do that its got to be a fault with the probe, as Paul said only way to repair is to lift the tile nearest the thermostat and put a new one in. Most ufheating suppliers used to supply conduit with there kits to insert the probe in but a lot don't any more..

And even if you have a spare probe, they're a real pig to push another one through the conduit, down the wall and into its place.

I generally use the conduit. But I would like to see somebody get another back in.

To the op.
How do you know it’s the probe? I would be testing the element first. The manufacturer will tell you the correct resistance readings.

Do you know the make of UFH and thermostat control unit.

From what I understand (which ain't much to be fair) is most thermostats with a digital display (even the cheap ones) give out an Error code if the probe fails.

If a Floor Sensor fails unfortunately you have to replace it or use a specialist thermostat. The floor temperature has to be registered, if not you run the risk of over heating the floor and burning out the cable as there is nothing to monitor the cable. The air sensor isn't usable on its own due to the temperature difference between the floor and thermostats mounted point.

We do however have a product we sell made by Elektra which was made for this purpose. It's called a Elektra IR, the IR Stands for Infra Red. This thermostat has a infra red beam which hits the floor and beams back the temperature of the floor. This thermostat is only programmable but is worth every penny.

Worth every penny if it saves taken tiles up 🙂

Only really of use in a kitchen or living area sadly but a great idea
