Floor heating in wooden floors

Heating in wooden floors

DEVI heating system can be installed in all kinds of wooden floors as long as the installation prefaces are observed.

The maximum thickness of softwood (density 400-600 kg/m3– pine etc.) is 2 cm.The maximum thickness of hardwood (density over 600 kg/m3– beach, oak etc.) is 3 cm.

Since wood is a natural soft materials it must be prevented from drying out. This is practically done by limiting the temperature on the floor surface to max. 27°C or what is prescribed by the flooring manufacturer.

Therefore, a floor sensor should always be used in order to control the temperature in the floor. The floor sensor has to be connected to thermostats like Devireg 550 or Devireg 535 with a temperature limiting feature. If the floor is heated with Devidry™ it is mandatory to fit the system with one of the two controller kits - the Pro Kit or the Plug Kit.

Required output

 The required output "qheat" must be based on a detailed calculation of the Room Heat Loss "qroom" in W/m² from an architect, consulting engineer or your local DEVI Office.

The required output for cables and mats qheat [W/m2] is calculated in the same way as for Total Heating, but 2 things must be observed:

1) the output on or below wooden floors must never exceed 100 W/m2
2) wooden floors on joists must not be heated with more than 80 W/m2

If the calculation reveals a required output exceeding 100 W/m2 an additional heating system has to be used to ensure a comfortable temperature in the room.

When using Devidry™ you can choose between two outputs, either 55W/m2 or 100W/m2. Both outputs can be used under wooden floors. 55W/m2 is for wooden sub-floors and 100W/m2 is for concrete sub-floors (and never on wooden sub-floors).

When using Devidry™ the Devidry™ Plug Kit (includes controller and circuit device) or the Devidry™ Pro Kit (includes Devireg™ 535 timer thermostat) is obligatory.
