Which type of pump is commonly used in heating systems?

Centrifugal pumps are commonly used in heating systems due to their ability to efficiently move liquids through a system. These pumps operate by converting rotational energy, typically from an electric motor, into hydrodynamic energy of the fluid.

In heating applications, centrifugal pumps are preferred because they can handle a continuous flow of water without experiencing significant turbulence, making them efficient for circulating hot water in hydronic heating systems or for transferring fluids in various heating processes. Their design allows for a smooth and consistent flow which is essential in maintaining the required temperature and pressure levels throughout the heating system.

Additionally, centrifugal pumps are well-suited for the relatively low-viscosity fluids, like water, typically used in heating applications, enhancing their efficiency and effectiveness in these environments.

While other types of pumps like submersible, gear, and diaphragm pumps have their specific uses in different applications, they do not match the effectiveness of centrifugal pumps when it comes to regular heating systems where high flow rates and lower head pressures are often required.
