Maximum temperature for underfloor heating
As mentioned earlier, it is lower than that for radiators and amounts to a maximum of 40–45°C for supply water and about 35–40°C for return water. The actual temperature for underfloor heating is usually lower, but the final value will largely depend on the construction and installation of the heating system, the material used for the floor finish, and the desired level of comfort. It’s important to note that the set temperature does not equal the felt temperature in the room.
What temperature for underfloor heating?
Underfloor heating has the advantage over radiators of providing even heat distribution. The downside is that it cannot quickly adjust the temperature. Therefore, finding the ideal setting is important. The following guidelines may be helpful. It is widely accepted that a comfortable air temperature is 20–21°C in living rooms, 24°C in bathrooms, and 18–20°C in bedrooms.
When considering what temperature for underfloor heating is appropriate, you can aim to achieve the above values by setting it to a maximum of 27–29°C in living rooms and bedrooms, and 34°C in bathrooms. Keep in mind that the maximum surface temperature of the floor should be 27°C.
Flooring and underfloor heating temperature
The difference between the felt temperature in the room and the temperature set for underfloor heating is influenced by the flooring itself. That’s why it’s so important to choose materials compatible with underfloor heating. They should not block heat transfer, as unsuitable coverings tend to do.
All floor panels available from us are designed for water-based underfloor heating, including vinyl panels from the IDÉAL collection.
