Heating Thermostat FAQ Guide


  1. What are Thermostats for Heating System?

A thermostat is the brain of a heating system. It allows you to control the temperature by turning the heating system on/off at appropriate time, ensure you get desired temperature always.


  1. How does a Heating Thermostat work?

Thermostat has a sensor to check if your room is at the desired temperature. When the sensor detected a lower or higher  temperature than the setting temperature in the thermostat, it sends a signal to thermostat to turn on or off the heating system .


  1. What are the types of heating thermostats?

l Water Heating System Thermostats

Water Heating System thermostats are used with water underfloor heating system and radiators. The max load is normally 3A. When the air sensor built in thermostat detected a lower temperature than desired temperature, thermostat will send signals to open the valve or actuator to let hot water flow in the underfloor heating pipes or radiator pipes to make the room warm. Vice versa.

l Electrical Heating System thermostats

Electrical heating system thermostats are used with electrical underfloor heating cables or mats. The max load is normally 16A. It could control the temperature of room or floor through the build in air sensor or remote floor sensor. When sensor detected a lower temperature than desired temperature, the relay equipped in the thermostat will close to power on the electrical heating cables or mats, so the underfloor heating system start heating. Vice versa.

  1. What is the best place to install a heating thermostat?

How your heating system will work depends on where you place the thermostat. If you put it in the wrong place, your utility bills are going to be higher.

l First, the thermostat should be placed somewhere in the center of your home. That way, it will give you the best average home temperature.

l Second, it should be placed on an interior wall.

l Third, place it between 130 and 150cm above the floor. This is important because hot air is lighter than a cold one. If you place it lower, you might get too low of reading. If you place it too high, your temperature reading could get too high.

l Fourth, don’t put your thermostat near a window or a door. Also, don’t locate it in direct sunlight and above air vents. Those are bad places because of a lot of air fluctuations in temperatures.

To sum up, thermostats should be placed at:

l Center place

l On interior wall

l 130-150 cm above the floor

l Away from windows, doors, direct sunlight, and above air vents
