Innovative Hot Water Recirculation Systems

Hot water recirculation systems deliver hot water to fixtures quickly without waiting for the water to get hot. Most hot water recirculation systems use a pump to supply hot water from a water heater to the fixtures. Hot water recirculation systems with pumps can operate by a push button, or by timers. However, instant hot water will only be available when the pump is activated. The pump recalculates cooled water that’s been sitting in the hot water line and sends it back to the water heater through the cold water line. It similar to turning on the hot water faucet and letting the water run until it gets hot, but instead of the water going down the drain, it is simply returned back to the water heater for reheating. When the hot water faucet is turned on, hot water is readily available.

An innovative and temperature controlled hot water recirculation valve which uses thermal convection to circulate the hot water, does not require a pump and is a much simpler solution.

A hot water recirculation system provides a means to get hot water from a water heater to your faucet or shower, while simultaneously sending cooled water (from the hot water lines) back to the water heater to be reheated. In addition to having the convenience of instant hot water at your faucets, these systems conserve water, save energy, provide faster hot water, and can save the average household 17,000 gallons of fresh water a year.
