How will this save me money? Calculate how many thousands of gallons of water you use while waiting for hot water each year. Money will be saved as the wait for hot water will finally be over. Moreover, you are conserving water and adding a great "creature comfort", instant hot water to every faucet/shower in your entire home.

How does it work? The pump recirculates hot water through the plumbing system in your home. When the water temp at the comfort valve hits a pre-determined temperature it closes. When you turn your sink/shower on, the hot water is at the valve and travels out of the fixture (remember the valve was installed at the farthest end of the plumbing run under a sink) - all fixtures/shower in that run will have the hot water available, instantly. No more waiting for hot water.

Will this work with electric and gas water heaters? Yes, as long as you have a water heater tank to re-circulate the hot water it will work.

Does this system heat my hot water? No, it is a hot water recirculator, it is a retro-fit to an existing water heater.

I have a tankless water heater, will this work in my system? The short answer is, no.

If you send the hot water back through the cold water pipes to the water heater, wouldn't you waste hot water when trying to get cold water? You lose a little bit because the "cooled off" hot water dumped into the cold water line heats the cold water a little bit. This is only important if you are drawing a glass of cold water. More than 99 percent of the cold water is used for other purposes, such as cooking, cleaning, washing the car and toilet flushing. The slightly warm "cold" water is perfectly fine for all these purposes.

What If I have multiple hot water branches?
You will need to get an extra comfort valve for every extra branch that you have.

What is a hot water branch? Hot water lines may branch off from your main hot water line, like to a bathroom, where it will supply hot water to a sink and bathtub.

Comfort valve installed under the farthest faucet from the water heater. The hot water recirculation pump moves the hot water from the heater throughout the pipe back to the heater through the cold water line. As the water heats up at the comfort valve, it closes. When a faucet is turned on, warm water is instantly available for use with no waste.
 
 

The comfort system pump is installed on your existing hot water heater "hot water line". The system puts hot water in the hot water line instantly, using a pump with a built-in timer at the water heater and a patented bypass valve at the point of use.

What about Installation?
The pump attaches to your existing water heater's hot water line out. Then you would attach a comfort valve at the water source (like a bathroom or kitchen sink). That's it!
