 Did you ever wish you did not have to wait so long for hot water?

Your wait is over, new technology makes it possible to retrofit a pre-existing home with a re-circulating system at very affordable pricing.

Here is how it works, a small energy efficient pump is installed at the water heater. The pump comes with

a built in timer for more energy savings. The second part or the system is a bypass valve which allows water to be pumped from the hot side of the water system to the cold side. This valve installs under a sink or lavatory at the fixture located the farthest away from your water heater. This eliminates water run off and conserves water. Can save up to 10,000 to 16,000 gallons per year per household. The energy efficient pump uses less electricity than a 25 watt light bulb.


What are the benefits of a re-circulating system.

The ultimate in convenience is having hot water instantly available at sinks, appliances and bathroom faucets. The elimination of time spent waiting is especially convenient in areas where the installation of low flow showerheads and faucets are required by law.

HWR improves the operating efficiency and effectiveness of household appliances including washing machines and dishwashers by having hot water available instantly, eliminating the lag time from the water heater to the appliance.

Users can save energy by setting the 24 hour programmable timer to produce hot water during peak demand times such as early morning and in the evening.

A low-watt, two-pole motor combined with low-flow performance ensures minimum water heater operating costs, pipe and water heater wear and energy consumption.

Significant water (and sewer) disposal savings, retaining the 12,000 to 38,000 gallons of water a typical U.S. home wastes annually waiting for hot water. Some fast-growing counties are making the installation of hot water recirculation pumps mandatory for all new construction projects.
