Household circulation pump refers to the circulation liquid pump used for conveying reaction, absorption, separation and regeneration of absorption liquid in the device. From function, they are mostly installed to overcome the pressure drop in the circulating system. Circulation pump refers to the pump role, centrifugal pump refers to the structure of the pump, both are completely two concepts. Its function is to provide power for the water circulation, constantly lifting the water up to ensure that the water can be circulated in the system on the base of the setted flow rate. Circulation water pumps are mostly used in heating and air conditioning water systems. For example, the circulation water pump is installed on the backwater pipe of the heating system, and the indoor temperature is increased by improving the hot water circulation.

Household hot water circulation pump has the characteristics of comfort, safety, stability, water saving, electricity saving, solar water heaters and so on. It is one of the necessary products in some houses. Normally, the home hot water circulation pump has two models to control the water temperature. One is temperature, the other one is time. We can set time, so as to ensure that there is no circulation when there is no one at home, so it will not waste energy. The user can also set their own hot water temperature, as long as the temperature of the system is lower than our required temperature, the hot water circulation pump will start to circulate, to ensure that the water temperature is suitable to us during our water using time.

How to choose a circulation pump

1. If the inlet water temperature of the home heating system is high but the return water temperature is lower, the circulating water pump can be installed to improve the indoor temperature. When choosing the circulation water pump, we should choose the low noise and energy saving water pump. The water pump in the heating system is mostly installed indoors. If the noise is very big when working, it will affect our daily life and rest.

2. Before choosing and installing circulation water pumps, we’d better determine whether your home can install circulation water pumps firstly. According to relevant regulations, some central heating houses are not allowed to install circulation water pumps without permission. If they install circulation water pumps without permission, the heating water circulation of the whole building will be affected, resulting in the heating problem of neighbors.

3. When we choose and buy circulating water pumps, we should pay attention to whether the form and performance of the pump meet the requirements.For example, the circulating water pump is installed on the heat network water supply pipe, and its working temperature can not be less than 80℃. We should choose the circulating water pump with high temperature resistance and so on.In the purchase, you also need to consider the relevant costs, such as pump prices, maintenance fees and so on.
