Unlike wet underfloor heating, electric underfloor heating cannot be controlled with just an Electric Switch and a Room Sensor/Thermostat. This is due to the temperature of wet underfloor heating being limited by the boiler output temperature, and a mixing valve on the manifold. For Electric Underfloor heating, should it be left on constantly, it will continue to heat up the floor, and may damage the surface or injure the occupant of the room. Therefore a floor-limiting thermostat must be installed in-line with the Genius Hub hardware to stop the floor from getting too hot.

Info
  • We do not sell floor limiting thermostats as these are often installed at the time of the Electric Underfloor heating being commissioned.
  • Different manufacturers also use different specifications of floor p[robeprobe, so if you are going to replace an existing electric underfloor thermostat with a new one, check that the probe is the same specification if you plan to leave the existing floor probe in place.

If you want to have time and temperature control from the app, you will need an Electric Switch, and either a Room Sensor or Thermostat, along with a standard floor limiting thermostat, such as one of the following:

1. Heatmiser DS1-E: The DS1-E will limit the floor heating to ensure that it doesn't overheat. You can then configure the DS1-E so that it only uses the floor probe and this can be set to a limit of 20º, 28º or 40º to stop the floor getting too warm. 

Here is a link for more information on how to install an Electric Switch and here is the wiring diagram.

2. Cosytoes MT3: The MT3 is a manual dial thermostat which can adjusted to limit the floor temperature from 5°C to 40°C.

3. OCEAN OHMT16: The OHMT16 is a manual dial thermostat which can be adjust to limit the floor temperature from 4°C to 45°C, with a switch to disable the underfloor heating on the front.


Alternatively, on/off control can be provided by the app and allowing for the ambient temperature to be controlled on the front of the third-party thermostat:

1. Purchase a HeatMat TPS-30, and a Single Channel Receiver from Genius Hub. The Single Channel Receiver will be wired into the setback terminals on the TPS-30 and the TPS-30 with its own floor probe will control the electric underfloor heating.

This means on the Heat Genius Hub app you can set the times that you want the temperature of the room to be at the heated temperature and the times that you want the room to be at the setback temperature. The temperature of the room will need to be set on the TPS-30 display itself. When you go away on holiday and want to turn the electric underfloor heating off you will need to turn it off on the screen of the TPS-30.

If you are going to use the Electric Underfloor Heating in a bathroom or wet room location please find below some tips:
  1. All wiring must be in accordance with the current I.E.E. (BS 7671) Wiring Regulations.
  2. The floor-limiting thermostat and the Electric Switch can be placed either inside or outside the bathroom. If the floor-limiting thermostat and the Electric Switch will be placed inside the bathroom it needs to comply with the wiring regulations in the UK please see this example.
  3. The floor-limiting thermostat and the Electric Switch can be placed at any height above the floor inside or outside the bathroom.
