When you turn on the hot water on your faucet or shower, first the hot water supply has to travel from the hot water heater to the fixture. After that, the water temperature only stays hot when in use. Once you shut off the hot water, it cools again in the pipes and the process starts over again the next time you use it. A Hot Water Recirculation pump is attached to the water through its supply line and recirculates the hot water from the heater to the fixture furthest from the source. This helps keep the temperature consistent and gives you instant hot water each time you need it.
In a typical new home (1 story / ~1,700 sq.ft.), a hot water re circulation system typically costs less than $1,000, including parts and installation. Additionally, a Hot Water Re circulation Pump can save you an average of 12,000 to 38,000 gallons of water per year, while remaining very energy efficient.
