FAQ

How does a circulating pump work on hot water?

A circulating pump moves hot water continuously or on demand through a closed-loop piping system. In hydronic heating applications, the circulator moves heated water from a boiler or heat source through piping to radiators, terminal units, or other heating equipment before returning it to be reheated. In domestic hot water systems, a recirculation pump helps maintain hot water availability by circulating water through the system, reducing the time users wait for hot water at fixtures.

What's the difference between a pump and a circulator?

A circulator is a type of pump designed primarily to move water or other fluids continuously through a closed-loop system. While pumps can be used to transfer fluid from one location to another, circulator pumps are commonly used in hydronic heating, cooling, and hot water recirculation systems where fluid repeatedly travels through the same piping loop.

What is the purpose of a circulator pump?

The purpose of a circulator pump is to maintain fluid movement through a closed-loop system. Circulator pumps help distribute heated or cooled water to where it is needed, supporting consistent temperatures, efficient system operation, and reliable thermal comfort in HVAC and hydronic applications.

Do recirculating pumps use a lot of electricity?

The amount of electricity a recirculating pump uses depends on its motor size, operating speed, control strategy, and how often it runs. Modern high-efficiency circulator pumps with variable-speed motors and intelligent controls can adjust performance based on system demand, helping reduce energy consumption compared with pumps that operate continuously at a fixed speed.
