The DEVI floor heating system can be used anywhere in the house no matter if the floor is constructed with floor boards on joists, wood-laminates or massive parquet on concrete.
Out of consideration for the wood the installed output must not exceed 100 W/m2 and not 80 W/m2 if the cables are laid in the air void between joists. In some countries regulations prescribe an even lower output. If building heat loss is higher than the maximum, re-insulation should be considered or additional heating sources are required in order to ensure a comfortable temperature in the room.
Under all circumstances it is important that the floor is well insulated below to ensure the best heating comfort and most economical result.
A combination thermostat is equipped with both a built-in room sensor which registers the temperature of the room and a floor sensor, which, when placed under the floor, registers and limits the floor temperature to the maximum of a chosen setting. The maximum floor temperature is provided by the manufacturer of your floor.
Product choise
For dry installations we recommend either Devicell™ or our newly introduced Devidry™.
When using Devicell™ insulation plates you should install a heating cable into the plate. We recommend the Deviflex™ DTIP-10, DTIE-6 or DTIE-10. A wooden floor should not be heated with cables with an output of more than 10W/m.
In combination with Devicell™ we recommend one of the following thermostats: Devireg™ 550, Devireg™ 535, Devireg™532, Devireg™132 and Devilink for advanced, wireless and easy to understand heating.
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™Kit (Includes controller and circuit device) is obligatory.
A floor sensor with max. limit function must always be installed with wooden floor applications and for regulation.
