1.Working Principle

Small automatic circulating pump for heating usually adopts the working principle of centrifugal pump, which utilizes the centrifugal force generated by the rotation of the impeller to pump hot water from the heat source, and conveys it to various heating terminals (e.g. radiators, underfloor heating, etc.) through pipelines. At the same time, the pressure difference and flow rate control mechanism inside the circulation pump can ensure the continuous circulation and stable supply of hot water.

2. Types and features

There are various types of small automatic circulation pumps for heating, including but not limited to the following:

• Electric DC brushless circulating pump: characterized by high efficiency, energy saving and low noise, it is suitable for various heating systems.

• Shielded pumps: compact, easy to install and maintain, suitable for heating systems with limited space.

• Booster pumps: can provide additional pressure to ensure that the hot water can be smoothly transferred to more distant heating terminals.

These circulating pumps usually have an automatic start/stop function, which can automatically adjust the working status according to the demand of the heating system, thus saving energy and improving the heating efficiency.

3. Precautions

When using the small automatic circulating pump for heating, the relevant safety norms and operating procedures should be strictly observed to ensure the safe and stable operation of the system.

If you encounter any problems or malfunctions in the process of use, you should stop the machine in time and contact professionals for overhaul and maintenance.

Avoid the use of circulating pumps in extreme weather conditions, so as not to cause damage to it or affect the heating effect.

In summary, small automatic circulating pumps for heating play a vital role in the heating system. Through proper selection, installation, maintenance and repair, you can ensure the normal operation of the system and energy efficient.
