11 best circulation pumps

Modern heating systems of private houses are equipped with circulation pumps. Thanks to this inexpensive device, it is possible to quickly and evenly heat up the coolant in different parts of the house, saving heat energy. The main task of the device is to move the fluid in a closed loop. The device operates from the electrical network, so bringing the pump will be useful only in the presence of a current of 220 V. When choosing a circulation pump, you need to know a few important points.

How to choose a circulation pump

1. Varieties. On sale there are two modifications that differ in design. Models with a dry rotor are distinguished by high efficiency (up to 80%), but they require regular maintenance, their service life is short (3-5 years), and they produce a lot of noise during operation. At pumps with a wet rotor, the efficiency is at the level of 50%, but they do not need to be serviced, the service life reaches 10 years, during operation the equipment is almost unheard of. Those who are sensitive to noise, it is better to give preference to models with a wet rotor.
2. Performance. Different heating systems require a pump with optimum performance. The homeowner needs to know the capacity of the boiler installed in the system. If a heating device of 40 kW operates in the circuit, the pump should provide a throughput capacity of 40 l / min (2.4 cubic meters / hour).
3. Lifting height The next important characteristic of the circulation pump is the head (lift height). Experts recommend sticking to a simple formula. A pressure of 0.6 m is required for 10 m of the pipeline. It is easy to calculate that a circulation pump with a lifting height of 6 m is suitable for a heating line with a length of 100 m.
4. Flow rate adjustment. A very useful option in the pump will be the ability to change the speed of water movement. Some models are equipped with a mechanical switch for 2-3 positions. The user selects the optimal mode based on the room temperature. More modern devices are equipped with electronic controllers that change the speed automatically. The maximum figure should not exceed 1.6 meters per second.
5. Power. Each circulation pump has an electric motor with a certain power. The thinner the pipes in the heating system, the greater must be the power of the motor. Otherwise, the pump will not be able to overcome the hydraulic resistance in the line. For small circuits, power up to 100 W is sufficient, and complex systems are equipped with models with motors over 150 W.
6. Coolant temperature. Each heating system has its own temperature regimes. If, when using a gas boiler, water is heated to + 80 ° C, in systems with a solid fuel boiler the heat carrier reaches a temperature of + 110 ° C. It is important to pay attention to the lower limit of temperature in case of irregular heating of the house in winter. Homeowners fill the system with antifreeze, which does not freeze in the cold. In this case, the pump must remain operable at -10 ° C.
7. Materials. To pump worked for a long time for the joy of the owner, you should find out what materials are made responsible parts and components. The body should ideally be cast iron, and the impeller and impeller should be of high-quality plastic.
8. Connection size. When inserting a circulating pump into the line, it is important to consider the diameter of the pipes. A cylindrical pipe thread is designated in inches, for example, G1, G2 or G3 / 4. The connecting size is indicated in the characteristics of the pump.
