The inner cavity of the heat exchanger connected to the first circuit 1 is supplied successively installed heating system 2 and the battery 4, and the outer 10 to the second circuit, which further set the maximum heating unit 6. 1 Il. The invention relates to a technique of heating, such as cottages, private apartment high-rise buildings, in which the accumulation electroerosive device is a consumer-regulator mains transformer substation (TS).Known heating system and hot water containing closed and open independent paths of heat transfer, heat exchanger and storage tank hot water, in which the heat exchanger is placed in a storage tank of hot water, and communicated with her through the output chamber (1).The disadvantages of this device the exchanger in the storage tank.The objective of the invention is to increase the efficiency of the device accumulation of electric heating.The task is solved in that the device accumulation of heat is further provided with peak heating unit, installed on the second circuit, and a heating device serves as the above-mentioned heat exchanger.The drawing is a schematic representation of the device the accumulation of heat.The device accumulation of heat, such as electric heating, consists of serially connected in a closed loop 1 heater unit 2 with the heating elements 3, such as a tubular electric heaters (heater), a storage tank 4, and a heating device 5, as well as peak heating unit 6 with the heating elements 7, for example ten. A heating device made in the form of heat exchanger pipe, the inner cavity 8 which is connected to the circuit 1 and the external cavity 9, connected with peak heating installation 6, forms a second circuit 10.Heating unit 2 can be combined with a storage capacity of 4. Then the heating elements 3 placed in the tank 4, the way the operate as follows. When the accumulation of the electric heating in the hours of the failure load curve of the power system or power supply TP (district or consumer) include heating elements 3 heating unit 2. There is a natural or forced circulation of the coolant, for example water, in a closed loop 1 (forced circulation can be carried out by a pump, not shown).

In the hours of the failure load curve include heating elements 3 heating unit 2. The coolant passing through the circuit 1, through capacity 4, passes into the internal cavity 8 of the heating device 5, where the heat exchange between the coolant loops 1 and 10. Since the heating unit 6 is off, the circulation loop 10 no (can be terminated by the valve or valves, which are not shown) and the fluid in the external cavity 9 is heated to a steady temperature. The preset temperature of the air may vary due to changes in the velocity of the coolant circuit 1.the 2nd mode. During the hours of peak load, when you cannot turn on the heating elements 3 installation 2, but you can include heating elements 7 maximum heating unit 6, a smaller capacity than system 2, circulates the coolant circuit 10. When the power of the heating elements cover the consumption of thermal energy heating device 5, the circulation circuit 1 is stopped.the 3rd mode. As in the second, but when the power of the heating elements 7 with covers over consumption of thermal energy heating device and 9, is charging the storage tanks 4 peak heater 6.The invention increases the efficiency of the device accumulation of electric heating, because firstly, it increases the efficiency of heat consumption; secondly, improving the quality of regulation of the temperature of the room; third, the accumulation electric heating makes better to smooth the load curve TA supply; fourth, allows the use of villages and manor houses, cottages or multi-storey houses with electric heating as consumers-regulators TA or energy system as a whole.Technical implementation of the device is not in doubt, for example in the manor houses with three-phase unified power input (3N, 380B, 50Hz), where electrified processes of heating, ventilation, hot water, household and personal farms. The accumulation device heating, containing a heating device, two independent coolant circuit interconnected by a heat exchanger pipe, internal Central cavity which is connected to the first circuit, is supplied successively established agrevo equipped with peak heating installation, placed on the second circuit, and a heating device serves as the above-mentioned heat exchanger.
