In this case, an optimal heat balance is established at different levels of the heated volume of the room. At the floor surface (at foot level), the air temperature is 22-26 ° C, in the ceiling zone - 18-20 ° C, and in the middle part (at head level) - 20 ° C (for comparison: in rooms with conventional wall radiators, the thermal layers warm up to 18 ° C, 22 ° C, 26 ° C, respectively). Due to this temperature regime, convection currents (rivers of warm air) - the culprits of drafts and flying dust - almost do not occur in the room. In addition, underfloor heating does not affect the interior of the room and does not make designers rack their brains over decorative camouflage of heating devices. There are two types of underfloor heating: water and electric. The former are used in houses with an autonomous heating system (cottages). In city apartments connected to the municipal heating network, easy-to-install and operate, as well as affordable electric cable heating systems are installed. Today, the Russian market offers a wide range of foreign and domestic electric underfloor heating. Among them are SST-Teplolux, Eltek Electronics, Chuvashkabel (all manufactured in Russia in 2013), Devi (Denmark); Ensto (Finland), Ceilhit (Spain), Raychem (Germany), Kima, Thermo (both Sweden), Nexans (Norway), etc. The products of these companies are certified and comply with all international and Russian electrical engineering standards (reliability, safety, etc.).
