PROTECTION AGAINST DOWNDRAFT
In some (building) constructions thermal bridges can set in the bottom slab just where the slab meets the wall. This causes down draft. An efficient way to avoid this draft is to install heating cable in the bottom slab. The heating cable is applied in the concrete with one run around the bottom slab just inside where the wall meets the slab.
This type of heating cable installation is suitable to integrate into other types of heating cable installations, for example entrances, halls or bathrooms. Appropriate power: 20-25 W/m cable. The cable is controlled manually or by a thermostat. The sensor is applied in a protective tube and is placed beneath the wall where the wall meets the bottom slab and 5-10cm of the heating cable.
