A traditional tank water heater only heats water at the tank. This results in a delay between turning on the hot water tap and hot water coming out of the faucet. A recirculating pump keeps the hot water moving through your pipes so the water is hot as soon as you turn on the hot water tap. At Hot Water Solutions, we sell, install and repair recirculating pumps.
How does a water heater work without a recirculating pump?
A traditional tank water heater continuously heats water that is stored in a tank. When a hot water tap is closed, the water flow stops and hot water left in the pipes sits there and cools. Once a hot water tap is opened again, any now cool water that was sitting in the pipes is pushed through before hot water from the water heater reaches the tap. This results in wasted water going down the drain, which can add up to hundreds of gallons throughout the course of a year.
How does a water heater work with a recirculating pump?
When a recirculating pump is added to a traditional tank water heater, water stored in a tank is continuously heated. Instead of water sitting and cooling in the pipes when the hot water tap is turned off, a recirculating pump continuously pushes this water back to the water heater to be reheated. Once the hot water tap is reopened, hot water is delivered instantly, resulting in less wasted water.
