Direct heating in concrete floors
Direct heating systems require an installed output of up to 150 W/m² and the heating cables are placed near the floor surface. Normally, heating cables or mats are placed in the lower part of a concrete layer with a max. thickness of 5 cm. Normally, the calculated output for a new and well insulated building would be 60 W/m² increased by approx. 30% in order to ensure a quickly responding heating system. This of course presupposes that we have knowledge of thermic losses of house. This heating combines with thermostat devireg™ 550. The heating of this type concerns daily operation. Installation It is important that the floor construction is well insulated so the downward heat loss is kept to a minimum. For bathrooms we always use black type of cables with double insulation to prevent moisture from entering the floor construction. |
