A wet room sensor is required if underfloor heating is required in a bathroom or wet room. The Polypipe wet room sensor can be installed in bathrooms, en-suites bathrooms and shower rooms. A room thermostat can then be fitted outside the wet area to control that rooms' temperature. The sensor (UFHSBOXW) is connected to the room thermostat using the cable(UFHFLOORW) . This distance can be extended to a maximum of 10m providing a similar type of cable is used. Generally the sensor is mounted on a wall.
