Installation of water pumps in the heating system has long ceased to be something unusual and prohibitive, except for this, to carry out their installation at home without any difficulties anyone can.
Such relatively small electric pumps can significantly increase the overall efficiency of the heating system, as well as the power parameters, which is especially important for a private house.
The installation in the heating system of an additional water pump to everything else improves the warming up of the internal space, both the private house and the apartment, and also significantly reduces the overall fuel consumption.
If you additionally connect a water pump to the heating system, it is possible to install a dryer for towels, as well as thermostats, in addition, you can use a heating pipe with a minimum diameter for a private house.
The scheme of connecting such water pumps to the common heating systems of a private house is quite simple.
With the right approach, as well as the availability of the necessary material and tools, anyone can connect a water-type pump to the private house heating system.

Connection features
In most cases, for a private house, a characteristic problem is that the heating system is not always distributed uniformly during the heating system.
Very often it happens that the temperature near the boiler is much higher than that observed in radiators located in the distant rooms.
In this case, the power indicators of the boiler itself do not play any role, and the problem arises, mainly because the circulation of the coolant is broken or the heating circuit is not assembled correctly.
To correct this situation, you can try to install pipes with a larger diameter, although this not only changes the circuit, but also requires a large amount of repair work.
The best option is to install a special water-type pump, in which the system operation will remain the same, and the coolant circulation will improve significantly.
It should be noted that if you install a pump in the heating system, the scheme of its operation will not change, but the temperature will be equalized along the entire length of the pipes.
In addition, it will be possible to get rid of the internal airing of the pipes, and also it will be possible to increase the heating area.
In this case, the correct selection of the appropriate pump is very important.
You should not buy a sufficiently powerful unit, as it will produce increased noise, although at full capacity, most likely, it will not work.
In addition, when selecting a pump, pay attention to such parameters as the diameter of the pipes, the density of the used coolant, and the temperature of the working water.
When choosing a pump for a heating system, it is best to consult with experts who will be able to recommend the best quality device.
Classification of
devices In order to help the heat carrier move through the heating system, dry and wet pump types are currently used.
In most cases, dry pump types are mainly used for large volumes of heat transfer, for example, if necessary, circulate water in the system in shopping malls or industrial facilities.
In their work they produce a loud noise, and in addition, are subject to vibration.

In devices of this type, the heat carrier does not come into contact with the surface of the rotor due to the fact that there are some design features that assume the arrangement of sealed chambers.
Installation of such pumps is carried out by professional specialists, since there is a certain specificity of the work performance. In everyday life they are not used.
In turn, wet type pumps have relatively compact dimensions and operating parameters that allow them to be installed on a heating system in a house or apartment.
In these pumps designed for heating systems, the working part is in the working fluid, which acts as a coolant.
In them, an electric current flows to the working elements through the starter.
Their main advantage is that due to forced cooling such pumps can work continuously for a long time.
In addition, pumps of this type in their work practically do not make noise and do not vibrate, which makes it possible to freely install them on the heating system in the house or apartment.
The main drawback of this water pump for a heating system is the relatively low efficiency.
Preparatory work for
Selection of equipment should be carried out only in specialized stores.
As a rule, with a pump for heating, there are special split threads, as well as an instruction in which you can read the manufacturer's recommendations for installation and wiring.
You should also take care of the purchase of filters, preferably if they are intended for deep cleaning.

In addition, it will be necessary to purchase a check valve that will help ensure the normal functioning of the entire heating system in the house.
You should also take care of the tool that you might need during the work. At hand, there should be a set of keys, pliers, and screwdrivers.
In addition, from the consumable material you need to purchase rubber gaskets and a small piece of pipe.
The pump connection diagram should allow free access to each device in the system, if necessary.
This is necessary in order that in the event of a pump failure or some other element of the heating system, they could be quickly repaired.
It is best to install the pump in the location where the expansion tank is connected. In this case, it will be possible to create a higher temperature in the declining section of the common pipeline.
Before starting the installation, you should carefully read the instructions, as well as familiarize yourself with the generally accepted rules for mounting this type of device to the heating system.
When carrying out work, you should adhere to the safety rules and follow the order of connection of certain elements.
Connection procedure
In order for the unit to be easily serviced and if necessary to carry out repair and recovery work, special ball valves must be installed on both sides of the device.
It is also necessary to install a cleaning filter, which will prevent various mechanical impurities, which may be contained in the coolant, from reaching the working parts of the unit.

It will be necessary to install a special valve, which will provide a way out of the system if air plugs are needed.
When installing the pump itself, it is necessary to check the direction of the arrow that is placed on its housing.
It must coincide with the direction of movement in the working fluid system.
The installation rules for devices of this type only mean their horizontal installation and this must be strictly observed.
After making the connection, the terminals that are on the outside of the unit must be at the top of the unit.
When making connections, it is necessary to monitor both their sealing and, if necessary, use special rubber gaskets.
It should also be provided that the outlet is grounded, through which an electric current will flow to the unit.
If the pipes are already in use, it is recommended to drain all water from the system immediately before installing the pump and also to clean it.
Mount the unit in strict accordance with the direction of the coolant movement, which is usually indicated on its housing.
After all the necessary work has been completed, it is necessary to fill the system with working fluid and only after that perform a test run.
It is also recommended to completely discharge all the accumulated air from the pipes immediately before starting the unit.

It is better to use units with automatic control, which are equipped with some types of protection. This will extend the life of not only the pump itself, but the system as a whole.
In any case, with the correct installation of the pump in the entire interior space of the house it will be possible to provide a comfortable temperature regime.
