The pump is a very important element of the heating system of the room. First of all, it solves the problem with the circulation of water in the pipeline. In addition, it allows the use of various wiring heating in the house. In this case, directly the pipes can be installed of small diameter due to the high run of water. As a result, the room heating time can be significantly increased.
The parameters of these devices are very important, however, the installation method also affects the efficiency of the heating system. Given this, it should be remembered that the circulation pump must be mounted in close proximity to the boiler.
What characteristics does the pump have?
Considering the circulation pumps, it should be understood that the main parameter is power. This indicator is measured in kW. Additionally, the manufacturer in the instructions indicates the performance of the device in liters per minute. The feed height can vary greatly. To install a circulation pump, pay attention to the diameter of the inlet as well as the outlet. The weight, as well as the dimensions of the unit, do not play a big role.
Selection of a quality model in the market
What to buy a pump for heating in a private house? How to choose a good manufacturer? Answering these questions, it should be said that an unequivocal answer can be given for companies. However, regarding the parameters, the consumer should emphasize for himself that the rated power of the device should be at least 0.1 kW. Thus, the capacity of the circulation pump will be in the region of 50 liters per minute.
For a private house, the area of which does not exceed 200 square meters. m., this will be enough. Next, consider the indicator of the height of the feed. In order to avoid problems when installing a circulation pump, this parameter should be at least 6 meters. Otherwise, excessive pressure will be applied to the heating system. The standard diameter of the inlet as well as the outlet is indicated 30 mm. The weight of the unit is on average 3 kg. With a device power of 0.1 kW, the model on the market should cost no more than 3000 rubles.
Is it possible to make a pump yourself?
You can make a pump for heating yourself, however, given the low cost of this device, it is not advisable to do this. Although if there are many spare parts, it can be assembled absolutely simply. First of all, you should choose a case for it. Usually cast iron is used for this purpose. Impellers are located in the upper part of the device.
They are most often made with brass. Thus, their wear is minimal, and they are able to serve for quite some time. Next, an engine should be placed in the casing to drive water into the system. However, it must separate from the impeller. In this situation, you can use a small cap. A terminal box must be under the motor. It is a plastic case in which there are various contacts. They are necessary in order for electric power to be supplied to the pump motor for its operation.
This happens after connecting the power cord. 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. Ultimately, the terminal box at the back is tightly closed with a protective cover. As a result, the pump is solid and invulnerable to dirt, dust and water.
