Individual heating in the apartment, inProduction room, office or home, much more economical than centralized. This depends primarily on the distance that the coolant passes from the boiler to the radiators.
There are two main ways to use such a system: with natural circulation and forced circulation.
In the latter case, the main one in it is a circulation pump, which pumps the coolant along the main line.
You will need
- - sealant-
- - rubber or silicone gaskets-
- - a set of keys from "to 22" to "to 36".
Select the pump for heating the room, taking into accountIts heat loss. In the calculation it is necessary to include thermal losses of external walls, thermal conditions, i.e. What is the average temperature in the building, the area of the room and other parameters. According to the theory, "the heat flow depends on the heat loss at the outer fences, which are directly proportional to the difference between the outdoor air temperature T1 and the temperature T inside the room, the area S of the heated room, the heat loss coefficient (W / m? K)". This calculation can be represented thus:
- With a radiator heating system, if the area (S) of the room is 80-120 m ?, then the pump should deliver a coolant of 0.4 m? Per hour, at 120-160 m? - 0.5 m? -
- under the "warm floor" system, if S = 80-120 m? - 1,5 m ?, at 120-160 m? - 2.0 m ?.
Install the pump in the heating system withRadiators on the return line near the boiler, where the lowest temperature. In apartments and houses of up to 200 m? This is rather arbitrary, since the coolant differs from the feed on the return pipe by 1-2 degrees. Therefore, in heating systems of small circuits it does not matter where to install the pump. Installation of the circulation pump for heating is carried out at the time of installation of the heating system, if it is operating, it is necessary to drain the coolant before this. You can not do this if you have cranes on the incoming and outgoing pipelines that block access to it. Then close them and start the installation.
Set it in the direction indicatedArrow on the body. It means the movement of the coolant. Before entering the pump, a cleaning filter should be put. Each threaded joint is protected with a sealant and a gasket between the mating parts. The pump must be installed strictly horizontally, otherwise the rotor can be damaged, besides, its constant "rumbling" will be heard. After installing and filling it with a coolant, open the central screw located on the top cover. A little liquid will come out of the hole. This will remove excess air from the pump. It can be connected to a 220V network either by means of a conventional electrical plug, or via an electric machine.
Install the pump in the system "warm floor" on the lineFeed. This will prevent any possibility of a rupture of the flow and air entering the system. The formation of air congestion is the biggest trouble in warm floors.
