11 best circulation pumps

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

Modern heating systems for private houses are equipped with circulation pumps. Thanks to this inexpensive device, it is possible to quickly and evenly warm up the coolant in different parts of the house, saving heat energy. The main task of the device is to move liquid in a closed loop. The device is powered by an electrical network, therefore, the pump will only benefit if there is a current of 220 V. When choosing a circulation pump, you need to know several important points.

How to choose a circulation pump

1. Varieties. There are two modifications on sale that differ in design. Models with a dry rotor are distinguished by high efficiency (up to 80%), but at the same time they require regular maintenance, their service life is short (3-5 years), and they make a lot of noise during operation. For 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, and the equipment is practically inaudible during operation. For those sensitive to noise, it is better to give preference to models with a wet rotor.
2. Performance. Different heating systems require a pump with optimal performance. The homeowner needs to know the capacity of the boiler installed in the system. If a 40 kW heater is operating in the circuit, then the pump must provide a throughput of 40 l / min (2.4 m3 / h).
3. Lift height. Another important characteristic of a circulation pump is the head (lift). Experts recommend sticking to a simple formula. For 10 m of the pipeline, a pressure of 0.6 m is required.It is easy to calculate that a circulation pump with a lifting height of 6 m is suitable for a heating main with a length of 100 m.
4. Adjusting the flow rate. A very useful option in the pump will be the ability to change the speed of water movement. Some models are equipped with a 2-3 position mechanical switch. The user selects the optimal mode based on the room temperature. More modern devices are equipped with electronic governors that change the speed automatically. The maximum rate should not exceed 1.6 meters per second.
5. Power. Each circulation pump has an electric motor with a specific power. The thinner the pipes in the heating system, the greater the motor power must be. Otherwise, the pump will not be able to overcome the hydraulic resistance in the line. For small circuits, power up to 100 W will be sufficient, and complex systems are equipped with models with motors over 150 W.
6. Heat carrier temperature. Each heating system has its own temperature regimes. If, when using a gas boiler, the water is heated to + 80 ° C, then in systems with a solid fuel boiler, the coolant reaches a temperature of + 110 ° C. It is important to pay attention to the lower temperature limit in case of irregular heating of the house in winter. Homeowners fill the system with antifreeze that does not freeze in the cold. In this case, the pump must remain operational at -10 ° C.
7. Materials. In order for the pump to work for a long time to the delight of the owner, you should find out what materials the critical units and parts are made of. Ideally, the casing should be cast iron, and the impeller and impeller should be made of high quality plastic.
8. Connection size. When inserting a circulation pump into a pipeline, it is important to consider the diameter of the pipes. Parallel pipe threads are indicated in inches, for example, G1, G2 or G3 / 4. The connection size is also indicated in the pump specifications.

We have selected 11 best circulation pumps for our review. All of them received approval from the expert community and were highly appreciated by consumers.
