Individual heating in an apartment, production facility, office or house is much more economical than centralized heating. This depends primarily on the distance that the coolant travels from the boiler to the heating radiators. There are two main ways of using such a system: with natural circulation and forced. In the latter case, the main thing in it is the circulation pump, which pumps the coolant through the line.
It is necessary
- - sealant;
- - rubber or silicone gaskets;
- - a set of keys from "22" to "36".
Instructions
Step 1
Select a pump for heating the room, taking into account its heat loss. The calculation should include the heat losses of the outer 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 losses on the outer fences, which are directly proportional to the difference between the outside temperature T1 and the temperature T inside the room, the area S of the heated room, the heat loss coefficient (W / m² K)". This calculation can be presented as follows:
- with a radiator heating system, if the area (S) of the room is 80-120 m², then the pump must deliver the heat carrier 0.4 m³ per hour, at 120-160 m² - 0.5 m³;
- with the "warm floor" system, if S = 80-120 m² - 1.5 m³, at 120-160 m² - 2.0 m³.
Step 2
Install a pump in a heating system with return radiators near the boiler where the temperature is coldest. In apartments and houses with an area of up to 200 m², this is rather arbitrary, since the coolant differs from the supply on the return pipe by 1-2 degrees. Therefore, in heating systems of small circuits, it does not matter where the pump is installed. Installation of the circulation pump for heating is carried out at the time of installation of the heating system, if it is active, then the coolant should be drained before that. It is possible not to do this if valves are installed on the incoming and outgoing pipelines, blocking access to it. Then you should close them and start the installation.
Step 3
Install it in the direction of the arrow on the body. It means the movement of the coolant. A cleaning filter must be installed before entering the pump. Protect each threaded connection with a sealant and a gasket between the mating parts. The pump must be installed strictly horizontally, otherwise the rotor can be damaged, moreover, its constant "rumble" will be heard. After installing and filling it with coolant, open the central screw located on the top cover. Some liquid will come out of the hole. This will remove excess air from the pump. You can connect it to a 220V network either with a regular electric plug, or through an electric machine.
Step 4
Install a pump in the supply line in the underfloor heating system. This will prevent any chance of flow rupture and air entering the system. The formation of air jams is the biggest nuisance in warm floors.
