Pump for heating in a private house: how to choose?

The pump is a very important element of the heating system of the room. First of all, it solves the problem of water circulation in the pipeline. In addition, it allows the use of various wiring in the house. In this case, the pipes themselves can be installed with a small diameter due to the high flow of water. As a result, the time of heating the room can be significantly increased.

The parameters of these devices are very important, but the installation method also affects the efficiency of the heating system. Given this, it should be remembered that the circulation pump must be installed in close proximity to the boiler.

What characteristics does the pump have?

When considering circulation pumps, it should be understood that the main parameter is power. This indicator is measured in kW. Additionally, the manufacturer in the instruction indicates the capacity of the device in liters per minute. The feed height can be very different. To install a circulation pump, pay attention to the diameter of the inlet as well as the outlet. Weight, as well as the dimensions of the unit, do not play a big role.

Selection of a quality model in the market

What kind of heat pump in a private house? How to choose a good manufacturer? Answering these questions, it should be said that companies can not give an unambiguous answer. However, with respect to the parameters, the consumer should emphasize for himself that the nominal power of the device must be not less than 0.1 kW. Thus, the capacity of the circulation pump will be around 50 liters per minute.

For a private house, the area of which does not exceed 200 square meters. M., This will be enough. Next, take into account the height of the feed. In order to avoid problems when installing a circulation pump, this parameter must be at least 6 meters. Otherwise, excessive pressure will be applied to the heating system. Standard diameter of the inlet, as well as the outlet hole is indicated 30 mm. The weight of the unit is, on the average, 3 kg. At a device power of 0.1 kW, the model on the market should not exceed 3000 rubles.

Can I make the pump myself?

It is possible to make a pump for heating by one's own hands, however, given the low cost of this device, it is not advisable to deal with it. Although if there are a lot of spare parts, then it can be assembled absolutely simply. First of all, you should choose the case for it. Usually cast iron is used for this purpose. At the top of the device are impellers.

They are most often made with brass. Thus, their wear and tear is minimal, and they last for a long time. Further, it is necessary to place the engine in the housing for running the water in the system. However, it must separate from the impeller. In this situation, you can use a small cap. Under the engine there must be a terminal box. It is a plastic housing in which there are various contacts. They are needed to ensure that the pump motor is supplied with electricity for its operation.

This occurs after the power cord is connected. Additionally, the control box must be in the terminal box. It is necessary to adjust the engine speed. Thus, the user has the ability to control the power of the device. Eventually, the terminal box at the rear is tightly closed with a protective cover. As a consequence, the pump is integral and invulnerable to dirt, dust and water.

Pumps of the company "Sprut"

The input, as well as the output port on the device, is of standard diameter, so there should not be problems with connecting to the pipeline at home. Of the features can be identified the presence of adapters with threaded connection. The maximum temperature of the pumped liquid in this case is 110 degrees. The pressure in the heating system should not be more than 10 bar. In this case, the model will work more efficiently, and the market for this heating pump in a private house is approximately 2400 rubles.

Is the "Sprut LRS" pump suitable for home use?

This pump is best installed in a house with a large area. The whole point is that its total power reaches 0.2 kW. The motor is equipped with a three-speed motor. The productivity in this case is as much as 200 liters of water per minute. Thus, the efficiency is in the region of 90%.

Input and output holes are available 30 mm each. If necessary, you can use adapters when mounting. As a result, it is possible to connect to any pipeline. Of the disadvantages, it should be noted the low temperature of the pumped liquid. The hydrogen index of water in this model is 6 pH. At the same time, the total mineralization of the liquid does not exceed 1500 g per cubic meter. M. It will cost "Sprut LRS" to the buyer for about 3000 rubles.

Characteristics of pumps "Aquario"
