How to install a circulation pump in the heating system

Hot water heating systems with natural or forced circulation can create heat in the room, regardless of the central heating.

In addition, it is almost 4 times cheaper, as the payment is spent only for natural gas, but not for the transport of heat transfer medium to the subscriber, and other services.

The system forced water through the pipes circulating pump moves, so you should install it correctly.

You will need

  • - Keys from 19 to 36 mm-
  • - filter-
  • - Reverse valve-
  • - Plug rezby-
  • - Bypass.



Define the parameters of the circulation pump. To do this, calculate the heat loss of the building according to the tables on the thermal conductivity of the materials. Also, consider the length of the pipeline, its diameter and the number of radiators. The use of forced circulation system, in contrast to the natural, and allows you to hide the main return line at the bottom of the wall. In the latter case, if the height of the small rooms, delivery pipe can cover part of the window, that breaks the appearance of the room, especially if held in front of the balcony door.


Install circulation pump in the pipelinereverse. Thus, it will interact with the cooled coolant, which would prolong the period of its operation. The forced circulation system, as opposed to natural, expansion tank and connect to the return line and not to the main duct.


Turn off the boiler. Close the valves on the inlet and outlet of the pump pipe water. Okrut nuts that the pump is bolted to them. Put the circulation pump horizontally, otherwise it will publish the impeller loud noise, causing rapid damage to your device. Typically, forced heating systems use low-noise three-speed centrifugal devices that create small water pressure, moving the large amounts of it.


Install the circulator as thean additional device to the system of natural circulation. To do so, attach pump and detachable filter threads, the diameter of which is similar to the diameter of the pump. In the case when the system is pressurized, buy check valve, which corresponds to the diameter of the threads of the device, in another embodiment (an open system), it is not required.


Fit the pump to the bypass line (underneath) tothe main or the return pipe, put a tap. Replace the bypass device to clear the air from the system. If this construction set vertically on the straight pipe close to the boiler, it is not necessary. Such a system ensures heating, even during a power failure.
