What Is A Recirculating Pump And How Does It Work?

A recirculating pump is a type of pump designed to move water in a loop from a source such as a hot water heater to a point of use and then back to the source. It is an energy-saving device that can be used to eliminate wastage of water and electricity. In this article, we will take a closer look at what a recirculating pump is and how it works in more detail.

What is a Recirculating Pump?

A recirculating pump is a type of pump that is typically used in homes that have hot water delivery systems. It is a device that pumps water from the hot water tank through the pipes to the desired water fixture, such as a faucet or shower, and then pumps the cooled down water back to the water heater.

How does a Recirculating Pump Work?

A recirculating pump works by maintaining a continuous loop of hot water moving through the hot water pipes in order to ensure hot water is readily available whenever required. The pump is installed on a hot water supply line near the fixture farthest from the hot water heater. The pump works by drawing hot water from the water heater and pushing it through the pipes until it reaches the fixture and then recirculating the cooled down water back to the water heater.

The pump can be operated manually with a switch, or it can be designed as an automatic system that operates via a thermostat that automatically turns the pump on and off as needed. Automatic systems are more convenient and are ideal for large houses that have a lot of hot water consumption.

Types of Recirculating Pumps

There are two types of recirculating pumps, namely, dedicated return line systems and demand-controlled systems.

Dedicated Return Line Systems

In dedicated return line systems, a separate hot water pipe is installed in the house that connects to the hot water tank, and the pump is installed on this pipe. The hot water circulates through this pipe and back to the hot water heater, ensuring that hot water is continually flowing, and there is minimal wastage.

Demand-Controlled Systems

In demand-controlled systems, sensors are installed at the point-of-use, that detect when hot water is required. When the sensor detects a temperature change, the pump is activated, and hot water is circulated until it reaches the point of use. Once the water reaches the desired temperature, the system automatically shuts the pump off.

Benefits of Having a Recirculating Pump

There are several benefits to installing a recirculating pump, including:

Water Conservation

A recirculating pump significantly reduces water wastage and conserves water by eliminating the need to run water while waiting for hot water to arrive at the fixture.

Saves Energy

Recirculating pumps can also save energy, as they reduce the amount of time the hot water heater needs to operate, which can reduce overall energy consumption.

Convenience

A recirculating pump ensures hot water is readily available when required, which can be more convenient for those living in the house who require hot water for their daily routine.

Conclusion

Recirculating pumps are an excellent energy-saving device that can provide comfort, convenience, and conservation in the home. By maintaining a constant flow of hot water through the hot water pipes, they can help save water and reduce energy consumption while providing readily available hot water whenever required. Installing a recirculating pump is a great investment in any home, and it is a cost-effective way to live sustainably while still enjoying all the comforts of modern living.
