Calculate the Temperature of an Underfloor Heating
Calculator for the temperature of the surface of the heated floor and of the air when using an underfloor heating. The air above the underfloor heating is heated up to a certain value depending on the heating's temperature. This warming can be calculated here. The temperature difference between the ground and the air depends only on the basic value, which indicates the power of the underfloor heating. The exact value can be obtained from the installer or manufacturer of the heating system. Values of 100 to 150 watts per square meter (W/m²) are typical. To calculate one of the two temperatures, please enter the other temperature in degrees Celsius.For the basic value, see the heating power.
Formula: Room air temperature = floor temperature - (basic value/8.92)1/1.1
With a basic value of 100 W/m², the difference between the floor temperature and the room air temperature is 9°C. For example, if you want a room temperature of 19 degrees, you need a floor temperature of 28 degrees.
Underfloor heating is often a very good solution for heating new buildings. It generates pleasant warmth from below, preventing cold feet. The heat is distributed evenly throughout the room. This also means less dust is stirred up, as there is less air circulation. Underfloor heating systems are very efficient and therefore have relatively low energy consumption. They are ideal for combining with a heat pump. Underfloor heating systems are space-saving and have no visible radiators. One disadvantage is that installation is usually more expensive than with other heating systems. Any repairs can be complex, so it is important to ensure the system is of high quality. Retrofitting underfloor heating can be very complicated and therefore expensive, as the floors have to be dug up.
Here you can convert metric units into customary and imperial units and convert temperature units.
