The Comfort valve is installed at the furthest fixture from the hot water tank. With a built-in timer, the pump allows hot water to circulate along the loop through the valve using the cold-water side as a return line. As the temperature rises to 100 °F, the valve closes, directing hot water to the tap, resulting in a constant availability of hot water. If you’re looking for a system that will give you instant hot water, save thousands of gallons of wasted water, and reduce your water bill, contact us today!
