A home water re-circulating pump is used to circulate domestic hot water so that any faucet or shower will provide hot water instantly upon demand.

Use less energy than a 25-watt light bulb
Did you know?
You can save up to 16,000 gallons of water per year, per household with a recirculating pump.
In Arizona, the average household consumes 126,632 gallons of water per year at an annual cost of $236.49. With new housing starts estimated to reach 54,903 per year by 2000, annual water consumption by new houses alone will total nearly 7 billion gallons at a cost of approximately $13 million per year. Were all new houses built in Arizona to include a Grundfos hot water recirculation system (with an average 200 foot supply line), water saved would total 16,534 gallons per year per household. The corresponding annual water bill would be reduced by approximately $32 and the energy bill by approximately $44. In total, hot water recirculation could save the state of Arizona nearly 950 million gallons of water per year and save new homeowners nearly $1.8 million in annual water charges.
The Basic Concept
Every homeowner gets frustrated waiting for hot water — but how many stop to think what happens to the 2-3 gallons of water that run down the drain during the wait?
Those gallons of water are wasted, and in an average household that takes four showers per day, that can add up to thousands of gallons per year. Multiplied over a subdivision of 300 homes, a community can have millions of gallons of water go down the drain and into the wastewater system every single year.
In a region where water conservation issues are rising in importance with a rapidly expanding population and a record economic expansion that has consumers looking for comfort, Hot Water Recirculation pumps such as those manufactured by Grundfos Pumps Corporation are a good solution to this problem.
In typical plumbing, water is pumped from the water heater through the pipes to the tap. Once the tap is shut off, the water remaining in the pipes cools hence the familiar wait for hot water the next time the tap is opened.
HWR pumps offer a solution to the problem by attaching to the water heater through the hot water pipe. By constantly circulating hot water through the pipes from the heater to the furthest fixture, the water in the pipes is always hot, and no water is wasted during the wait. In an average new home, HWR systems typically cost less than $ 500,00 including parts and installation.
