Domestic hot water circulation pump – application

A domestic hot water circulation pump is installed in the domestic water system and is responsible for the uninterrupted circulation of the liquid from the heater to the draw-off point. Thanks to it, hot water flows from the tap - practically immediately after turning on the tap. This is an excellent technical solution that saves time and money. You no longer have to wait for the cooler water to drain from the pipes. Excessive exploitation of the installation is also limited, associated with the need to heat the water and unnecessary waste of cold water.

What is worth knowing about the construction of circulation pumps?

DHW pumps are quite complex devices in terms of construction. The main structural elements are the external protective casing of the device, the rotor and the motor. Modern circulation pumps have a ball (or spherical) motor, which, unlike wet rotor motors, does not require the use of a rotating bearing shaft.

Most pump models operate at a constant speed, which guarantees high energy efficiency - unlike devices operating in continuous mode. They are also equipped with protection against so-called dry running.

Before choosing a specific device, you should pay attention to the exact specification, taking into account such features as: lifting height (pressure generated by the pump to balance the sum of all flow resistances), power consumption and pump body (manufacturing material - most often cast iron, stainless steel or brass).
