Constructive execution of such an autonomous hot water system complicates its manufacturing, limits the climatic zones of use and use in individual buildings, where there is no central water supply.

Known water-heating boiler system and apparatus for controlling its operation (US Pat. RU №2092744, cl. F 24 N 1/08, in 1997), comprising a heat exchange chamber (a chamber ignition, combustion chamber, water chamber with a coil and a chimney ), adding water to the tank, circulation pump, the hot water supply device, the burner and the operation control device of the system.

Lack of hot-water boiler system in its complexity, the relative bulkiness, the possibility of leakage of harmful ingredients used in its work, which limits its use in a domestic environment.

Known heat pump (AS USSR №892031, according to cl. F MKI 04 F 1/18, of 1981), comprising a fluid reservoir with a funded highway, which has consistently set the heater, refrigerator, and a check valve, and a main chamber of variable volume, connected between the tank and the heater, further variable volume chamber positioned between the valve and a reflux condenser, a movable lid which is spring-loaded and is kinematically connected with the rod by means of a lid main variable volume chamber. Also on the line are placed further two valves: one - between the reservoir and the main chamber, and the other - for the second camera.

The disadvantages of such a system are relatively low liquid heating efficiency due to the outdoor location of the heater in a heated object, issuing only a specific heated liquid portion in the consumption of the system, a well-defined geometrical position of the main chamber for additional cameras, but also for mechanical moving parts, causing more difficulty in providing them with reliable sealing, resulting in unnecessary electricity costs.

Known and accepted as a prototype heat pump system (US Pat. RU №2173434, IPC F 24 H 1/08, F 25 B 29/00, F 04 F 1/04, in 2001), comprising performing in the form of a sealed tank constant volume a cover main tank inside which has a liquid level sensor and a heater in the upper part of its installation complicated, adjustable in height relative to the liquid level sensor outlet port, the lower end of which is located below the cap main tank, and at the bottom - an inlet formed in a tank constant volume communicating with the atmosphere, an additional capacity placed no lower than the main container mounted on the entrance to the additional capacity check valve, the heating element is disposed between the main and additional tanks, but also located in the flow line mechanical control device and a control unit , which is associated with a heater and liquid level sensor elektrotermodatchik attached to the return line in which a check valve.

The disadvantages of the known heat pump system is an extra tank directly behind the main tank, while heated to the liquid boiling point, entering from the main tank into an additional container, partially filled with cold liquid, losing a significant portion of the heat energy and then cools the liquid fills the heating elements, thus there is a additional heat loss (the total heat loss is about 50%), and to achieve the desired temperature in a heated room, an additional power consumption, which reduces the efficiency of the heat pump system.

Availability of basic and additional capacities in the form of two separate units connected by highway, but also complicated, height-adjustable outlet installed in the main tank, complicating the design of the heat pump system, at the same time when placing additional capacity within the heated space may leak fluid vapor in a heated room that worsens ecological heated space and for removal of liquid vapor in the atmosphere is necessary to use additional devices, which complicates the design. Additionally, during operation in heat pump system known main air tank is formed, which reduces the efficiency of the installation work, as there is the need for periodic manual removal of air does not ensure that the installation in the automatic mode.

The objective of the present invention is to provide such a facility for heating, which would have a high efficiency, have simplified the design for sustainability of heated space and installation work of heating in automatic mode.

This object is achieved by the fact that in the known heat pump plant comprising constructed as a pressurized tank constant volume with the inlet and outlet and a lid main tank, inside which there are connected to the liquid level sensor control unit and termoelektronagrevatel formed into a tank inlet additional capacity, the check valve and the heater units, additional capacity, further comprising coupled to a liquid level sensor control unit and a cover, on which is fixed the condensing device is designed as a removable tank installed for the heating element to cover the main tank, which at the same time the bottom of the additional container , wherein the cover main tank fixed placed in an additional container inlet main tank with a check valve and an automatic removal of air formed by two reciprocally valves connected threaded tube, with one of the reciprocal valve mounted on the nozzle main container in the bottom of which is fixed an outlet with a valve mounted thereon, comprising a removable spring configured with a predetermined elasticity.

The presence of the valve with a removable spring having a predetermined elasticity, is installed on the outlet pipe main container provides the required vapor pressure in the main tank and thus the fluid temperature therein above 100 ° C, and as additional capacity is available for the heating element, with the aforementioned temperature fluid enters directly from the main tank into the heating elements, which reduces the heat loss and thus increases the efficiency of the installation for heating.

Placement of additional capacity on the lid of the main tank eliminates line for liquid feeding of additional capacity to the main inlet and use the basic capacity as outlet additional capacity, which simplifies the design of the installation for heating.

Attaching the cover additional capacity condensing unit provides an efficient condensation of air and liquid vapor in additional capacity, and it eliminates the leakage of the liquid vapor from the additional capacity and getting them in a heated room, which ensures sustainability of heated space and therefore the use of the installation for heating directly into the heated rooms . The installed capacity in more liquid level sensor ensures that it contains the minimum required amount of fluid that prevents the ingress of air from the additional capacity to the heating system in an emergency (for example, a leak in the heating system). In these cases, a liquid level sensor control unit gives a command to disable the installation of the heating network.

The presence in the heating apparatus for automatic venting device for accumulating in the process in the main tank, the installation provides for heating operation in the automatic mode, since there is no need for periodic manual removal of air from the main tank.

The drawing shows a diagram of the inventive heating installation.
