The conductors of the heating sections is made from graphite and are installed symmetrically in the holes of the lateral tubes of each section are connected in parallel and the current-carrying tire (see patent RU No. 2431083, IPC F24D 3/04).

A disadvantage of the known solutions is the low safety of operation due to the heating of the coolant by passing it current.

The closest technical solution to the claimed is heating - floor heating, consisting of a heat generating unit and a heating sections, made of interconnected tubes, the cavity of which is filled with liquid coolant. Inlet heating sections of the heating system is connected to the hydraulic output of the heat generating unit, the hydraulic inlet connected with an outlet of the heating sections. The heat generating unit is made in the form of the stator of the induction motor, naked�awawdeh coolant, located in the inner cavity of its secondary winding and providing its movement in the pipes of the heating sections, which heats the air. With the help of temperature controller connected to the temperature sensor of the coolant occurs enabling or disabling the heat generating unit from the network (see patent RU No. 119855 U1, IPC F24D 3/04).

The disadvantages of the known solutions are the design complexity, reduced effectiveness and efficiency due to the complexity of the design heat generating unit and the need for frequent on / off depending on the temperature in a heated room.

The technical result of the claimed technical solution is to simplify the design and increase efficiency of use.

The technical result is achieved in that in the heating system of the building containing the heat-generating unit and a heating section, made of interconnected pipes located in the floor, the cavity of which is filled with liquid coolant, and the heat generating unit is provided with a node on or off from the mains, connected to the temperature sensor of the coolant, the inlet of the heating sections is connected with an outlet of the heat generating unit, and the outlet - with the input of heat generating nl�ka, thus the heat generating unit further comprises a heat storage capacity, interacting with electric boiler or with tena, the node enable or disable the heat generating unit from the network is made in the form of a control unit interacting with the temperature sensor coolant heat storage tank and the inlet of the heating sections is connected with an outlet of the heat storage tank through a thermostatic mixing valve, which is connected by pipeline with the return pipe of the heating sections.

Introduction to the heat-generating unit heating the building's heat storage capacity, interacting with electric boiler or with tena, the supply control unit generates heat energy, heating the coolant in the heat storage tank to an optimum temperature of 85°C, consuming electricity periodically, for example once a day at night time, during the period of minimum load on the power outlet and discount rate for electricity, the volume of the heat storage capacity is sufficient, then during the day to expend heat energy for operation of the heating system of the building, increasing its effectiveness while simplifying the design.

The connection of the inlet of the heating sections otopi�individual system with the release of the heat storage reservoir through a thermostatic mixing valve, connected by pipeline with the return pipe of heating sections, allows the most effective use of the stored energy to the coolant, creating in a heated room the optimum comfortable temperature through the coolant supply to the heating section of the system at a temperature depending on the outdoor temperature. For this set up (manually or automatically) thermostatic mixing valve to the desired temperature and valve, mixing the coolant flowing from the heat storage tank with coolant coming out of the pipes of heating sections, and feeding it into the heating section, increase the efficiency of the system.

Teploe�airoldi block may consist of a heat-accumulating tank 4 with the heating elements 6 and automatic crane for 5 vent air from the system when it is filled with water (Fig.2). The heat storage capacity may consist of several containers, installed in series with each other (not shown). At the entrance to the heating system set pressure regulator 7 after themselves to maintain the required pressure in the system. The heating system includes heating section, made of interconnected tubes 8 located in the floor, the cavity of which is filled with liquid coolant (water). The heat generating unit provided with a control unit 9 for switching on and off electric boiler 1 or the heat-accumulating tank 4 with the heating elements 6 and is connected to an electric output of the temperature sensor 10 of the water in the heat-accumulating tank 4. The outlet of the heat storage container 4 is connected with the inlet of the heating sections of the pipeline, which in the course of the coolant from the heat storage capacity installed: thermometer 10 to 100°C, a pressure gauge 11 to 0.6 MPa, thermostatic mixing valve brand TVM-H 12, the ball valve 13, pump 14, the valve 15, thermometer 16 to 100°C for the temperature control of the coolant at the inlet of the heating sections. Thermostatic mixing valve 12 is connected by a conduit 17 with a return pipe 18 heating sections, equipped with thermometer and pressure gauge 19 20 to determine the temperature and pressure t�of planocytes at the output of the heating sections. The heating system is also equipped with a safety valve 21 for flushing the coolant in the drain when the pressure in the system and diaphragm expansion tank 22 connected to thermal storage capacity of 4, to compensate for volumetric expansion of the coolant when heated.

The building heating system operates as follows.

Initially the system is filled with water during the automatic flushing of air through the valve 5 mounted on the heat-accumulating tank 4. The system pressure is maintained using a pressure regulator 7. The control unit 9 includes a pump 2 and two minutes includes electric boiler 1 (Fig.1) or thermal storage capacity with 4 heating elements 6 (Fig.2). The heating water is heated in the boiler 1 and 2 is pumped into a thermal storage container 4 (Fig.1) or tena 5, directly heated water in thermal storage tank 4 (Fig.2). When water is heated to 85°C in a thermal storage capacity of thermometer 10 sends a signal to the control unit 9, which turns off the electricity. Use for heating the coolant in thermal storage capacity of the period of minimum load on the power outlet and discount rate for electricity significantly reduces the cost of operation of the heating system, increasing the efficiency of its work. When incl�nom the pump 14, the fluid from thermal storage tank 4, mixing with return water of heating sections, supplied through a conduit 17, with thermostatic mixing valve 12 for receiving at input the desired temperature enters the tube 8 heating sections for heating through Underfloor heating room air. At the entrance of the heating sections in the winter time at a design outdoor temperature of -31°C set temperature 45°C, in the spring when the temperature of the outside air temperature of the coolant is reduced.

The building heating system of simplified construction and increased efficiency in the work will find application in the field of engineering.
