Warm floors (Electric and water) in recent years become more widespread as a means to enhance the comfort of human habitation in the area. Analysis of technical and economic characteristics of the floor heating systems showed that, beginning with a warm floor area of 5-10 square meters it is advisable to make water. When the floor heating device for the purpose of improving comfort of living, its calculated heat does not exceed 50 W/m2, so in this case, floor heating is considered as an addition to radiator heating, especially in demand in rooms with floor covering such as 'tiles' (kitchen, bathrooms, etc.). Feature of the system of floor heating – a large duration of work compared to radiator heating system, reaching for individual facilities to a year-round. Peter Thiel has similar goals. This schedule includes two options for connecting to the underfloor heating system: the total area of warm floors for more than 20-30 m2 advisable to connect a warm floor to a separate pump and mixer circuit in the boiler room with individual heating schedule. With a smaller area underfloor its contours advisable to connect to the loop recycling of hot water with the use of special units for the temperature limiting floor coverings to the required size. In the latter case, this decision all the more justified, that warm floors are arranged just in the premises with the points parsing of hot water – bathrooms and kitchens. In both cases, the power of the floor heating must be considered in the selection of the boiler for individual heating systems.
