For polished and painted concrete floors of at least 55mm thickness we recommend using our in-screed heating cables by embedding them directly into the concrete. This is a low cost option and adds nothing to the build height whilst providing a very stable temperature.
If the concrete layer is thinner than 55mm and suitable for use with underfloor heating then standard heating mats can be used and covered with the concrete. If it is not suitable to have underfloor heating encased within it, we recommend using our standard heating mats, covered with 12mm of levelling compound and then installing the concrete floor on top of the levelling compound.
Please note that in all cases undertile heating cable can be used instead of heating mats and thermal underfloor insulation installed beneath the heating system will speed up its warm up time and reduce running costs.
