The most comfortable temperatures for the human body are 18- 20°C at eye height and 22- 24°C by the floor.
If your feet are cold, your whole body feels cold. The use of a floor as a heating source has several advantages. The floor surface gives a uniform heating in the room. Most of the heating (80%) is heat radiation and approximately 20% accomplished by heating up the air. With the floor surface as heating source, the floor temperature is only a few degrees higher than the desired room temperature. In well-insulated rooms a floor temperature of 23°C gives a room temperature of 20°C. Floor heating is a low temperature system that provides the most comfortable enviroment. Radiators form a high temperature system that gives high temperatures at the ceiling and a high air circulation. The nature of floor heating gives the opportunity to save energy since the temperature in the room can be kept 1-2 °C lower compared to systems using radiators.
Other advantages are:
- Low temperature heating = energy saving
- Better comfort
- No space occupied by heating devices
- Rooms easier to furnish
- Less dust in rooms
- Low installation cost
- No maintenance
