STS-02T Series

The STS-02T Series D’MAND® Systems can be used with both tank and tankless water heaters on standard plumbing or dedicated return lines in existing homes, new home construction or commercial applications. At the push of a button, or with a motion sensor in place, the D’MAND® system activates and pumps the ambient (cool) temperature water back to the water heater saving both water and energy in the process. When the hot water arrives at the D’MAND® system, the built in Thermister automatically shuts the pump off and closes the IFC Valve. Now you have hot water instantly at the fixture and anywhere else plumbed off the main line.

STS-02T models are designed for use in large homes or commercial buildings where the distance from the water heater to the farthest fixture is greater than 100 feet. The STS-02T models carry a five year warranty and weigh 16 lbs. Dimensions are 16" wide, 9" deep, and 6½" tall. (This model is adaptable to any tankless water heater. Please review our tankless water heater section for proper sizing.)

The D’MAND® System is available in four models. Pause your mouse over the other model numbers to see the differences in the photos. Click any model number to add that item to the shopping cart. (If you want to buy more than one, you can change the quantity in the cart later.)
