Even with a water heater, sometimes hot water can take a while to get to its intended location, especially if a house if large and the plumbing system is spaced out. Say you are taking a shower and turn the nozzle to hot, but it takes a while before the warm water actually arrives, with you just standing under cold water until then. That is gallons and gallons of water being wasted as you wait for the warm water. A hot water recirculating pump helps save water by looping the water in the hot water lines back into the water heater to be reheated instead of just being washed down the drain as you wait for the water to warm up.

What is a Recirculating Pump?
There are a few different types of recirculating pump systems: gravity fed, traditional, instant, hydronic closed, hot water open, and on-demand. Each system has its pros and cons, so choosing the one that fits best for your house is important.
Gravity fed: Located below the hot water taps, it runs 24/7 to help make the hot water rise to the top of the tank and the cold water stay at the bottom in a scientific term called thermosiphoning. With hot water at the top of the tank, it is instantly ready whenever the hot water taps are turned on.
Traditional: A dedicated return line for hot water pipes that travels all the way from the water heater to the furthest tap.
Instant: Pushes water into the cold tap line, creating a loop of hot water so there is hot water in all plumbing appliance taps if needed.
Hydronic Closed: Typically installed as heated flooring, closed system recirculating pumps act as a huge radiator. The pump is hooked up to a boiler and refills the hot water in the pipes by removing excess oxygen and sending cool water back into the boiler.
Hot Water Open: The standard recirculating pump system, it is connected to the main water line through the water heater.
On-demand: Uses the least amount of energy while saving the most water since the pump is activated by a switch. It automatically shuts off when the motion sensor detects that hot water has arrived at the tap.
Get Hot Water Quicker
Recirculating pumps are often seen in households with traditional tank water heaters as the pump helps the heater warm water even quicker. Recirculating pumps are not needed with tankless water heaters because hot water is created on demand with those, and does not sit and refill in the tank like regular water heaters. Recirculating pumps also help keep your pipes from freezing and bursting as it always insulates the pipes since the hot water is pumped continuously through them.
