S-Series Pump

S3-Series Pump

The D'MAND Kontrols® S3-Series converts standard plumbed homes into D'MAND Kontrols® Systems. At the push of a button, the S3-Series pumps cold water sitting in the hot water line into the cold water line and back to the water heater. The "temperature sensor" automatically shuts off the pump allowing the pump's IFC (Integral Flow Control) Valve to close when hot water arrives at the fixture. Now you have hot water within seconds at the fixture and anywhere else plumbed off of the main line.

The S3 series models are recommended for use with standard plumbing systems in homes up to 4,000 square feet with a tank type water heater. They are suitable for use in most homes and small businesses. The weight is 9 lbs. Dimensions are 6.5" wide, 5.25" deep, and 4.75" tall. (This model is adaptable to any tankless water heater. Please review our tankless water heater section for proper sizing.)

The patented PDV (Check Valve) is built right into the pump housing, reducing the number of external devices. It is suitable for runs up to approximately 120 feet. The pump carries a five-year warranty.

The S3 series pump is available in two configurations. The base configuration is the S3-100 Kit as shown below.

 

S3-100 Series

The S3-100 Series D’MAND Kontrols® 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 light commercial applications. At the push of a button, or with a motion sensor in place, the D’MAND Kontrols® 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 Kontrols® System, the built-in thermistor automatically shuts the pump off and closes the IFC Valve. Now you have hot water within seconds at the fixture and anywhere else plumbed off the main line.

S3-100 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 120 feet. The S3-100 models carry a five-year warranty and weigh 9 lbs. Dimensions are 6.5" wide, 5.25" deep, and 4.75" tall..  (This model is adaptable to any tankless water heater. Please review our tankless water heater section for proper sizing.)
