Hot Water Recirculation Basics |
What are you waiting for?
Convenience and conservation are here now. You know what it’s like to run the tap and wait for the shower to heat up before stepping in. Waiting for hot water is inconvenient and it wastes time and money. With a hot water recirculation system, the comfort of hot water in an instant and the elimination of water waste are a turn of the knob away.
What is Hot Water Recirculation?
Hot water recirculation means a continuous flow of hot water in the hot water supply line of your home. Without a “recirc” system, unused hot water in the line cools and must be evacuated before hot water from your hot water heater can reach the desired faucet. As a result, gallons of water are wasted – and so is your time. |

This system uses the cold water supply line as the “return-line” to the water heater. A circulator pump is used to create a pressure differential that allows the cold and cool water in the hot water supply line to “by-pass (at low volume) into the cold supply line through a patented thermostatically controlled valve that is mounted under the sink furthest from the water heater.
| FEATURES AND BENEFITS |

- Installs in less than one hour
- No electricity needed under the sink
- Built-in timer & line cord
- Use less energy than a 25-watt light bulb

Arizona
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 2008, 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, 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 home owners nearly $1.8 million in annual water charges.
