The invention relates to a heating engineer and can be used in heating systems private homes and cottages.

Analogue of the invention is sectional heating radiator, aluminum wheels, containing a number of longitudinal finned tubes and the upper and lower headers (see patent N 2059933, 24 D 3/12, 19/00, 28 1/10, 1993).

The disadvantage of this device is the inability to regulate the size of the heating surface of the heater depending on the temperature changes of outdoor air during the heating season.

The disadvantage of the prototype is that there is no way to adjust the surface area of the heating device in accordance with the changes in the outside temperature.

The invention is directed to regulate the area of the heating surface.

This is achieved by the fact that the block heater containing finned blocks of metal casting in the form of boxes, equipped with nozzles for inlet and outlet of the heat carrier made of composite, consisting of upper, intermediate and lower blocks, isolated from each other insulating jumpers and equipped with shut-off valves for the passage of fluid from the upper block in the interim, from the last intermediate in the lower unit, all units equipped with nozzles for the supply of fluid, a nozzle for draining the coolant from the heater is located in the lower part of the lower block.

In Fig.1 shows a General view of a block heater in Fig.2 - section 1-1.

Block atopical the x from each other insulating jumpers, and which has openings for the passage of coolant and shut-off cocks.

The drawing shows a block heater comprising upper finned block 1 of metal casting in the form of a closed box with flanges, and a rounded top, intermediate fin block 2 is made with open flat top flange and the bottom of the finned block 3 open flat top flange and a rounded bottom. Between the blocks are jumpers 4 and 5 of insulating material, representing the pallets with side holes 6 and 7. Jumpers are equipped with shut-off valves 8 and 9 for the passage of fluid from the upper block in the intermediate, and then in the lower block. The blocks contain the branch pipes 10, 11, 12 for the entry of hot water, and the lower block the inlet 12 to outlet chilled water. The blocks are connected by bolts 14.

Intermediate blocks 2 may be two or more, depending on the size of the heated space.

Work block heater is as follows. To maintain in the premises specified design temperature shut-off valves 8 and 9 must first be open. In this case, the hot water enters the device through Patras is livemos room is exceeding a predetermined temperature, close the stopcock 8. Then in the upper block 1 water circulation stops and the unit cools down. If you close the shut-off valve 9, and the intermediate unit 2 water circulation ceases and the intermediate unit also cools down, only works the lower unit 3. Jumpers 4 and 5 of insulating material prevents heat transfer from the hot block to the cold. If necessary, the valves 8 and 9 can again be opened. Thus, it is possible to adjust thermal capacity of the device depending on the desired indoor temperature due to the decrease or increase of the heating surface.

Block heater containing finned blocks of metal casting in the form of boxes, equipped with nozzles for inlet and outlet of the coolant, characterized in that it is made of a composite consisting of upper, intermediate and lower blocks, isolated from each other insulating jumpers and equipped with shut-off valves for the passage of fluid from the upper block in the interim, from the last intermediate in the lower unit, all units equipped with nozzles for the supply of fluid, a nozzle for draining the coolant from the heater location is
