A balcony or loggia, securely and of high quality, can become a full-fledged additional room, ideal for relaxing after a hard day's work. Or even a full-fledged separate office with office equipment. The main thing is to provide comfortable heating of a balcony or loggia. For this reason, a warm floor on the balcony will be simply irreplaceable, especially in the winter season. It can be installed with any floor covering, even in places with high humidity.
Regarding the required specific power of underfloor heating per square meter, there are several positions. For example, some manufacturers believe that if underfloor heating is planned to be used for additional (rather than main) comfortable heating, together with other heating devices, then underfloor heating with a reduced power density should be chosen: 130-140 W/sq.m. In our opinion, this does not make sense at all: the cost of such a warm floor will not be much lower, but it will take much longer to heat the surface and, as a result, consume more electricity. We recommend in all cases to use electric underfloor heating with a specific power of 150 or 160 W per square meter. This power is also ideal for balconies and loggias.
