D’MAND Kontrols, a brand of ACT, Inc. formerly known for Metlund, develops hot water recirculation systems designed to provide hot water on demand while reducing water and energy waste. Its controller adds intelligent control to an existing compatible recirculation pump, operating when hot water is requested rather than circulating continuously. The company’s proprietary Delta-T technology is designed for use with water heaters with or without a dedicated return line.

D’MAND Kontrols products serve residential and commercial applications, including new construction and retrofit projects, as well as hotels, apartments, and offices. The company also offers systems and parts through retail and distribution channels, alongside installation support and assistance in choosing a solution. According to the brand, its systems can help households save 8,000 to 12,000 gallons of water annually and cost less than $2 per year in electricity to operate. Actual hot water delivery time depends on the pump and plumbing configuration. Made in the USA with global components, D’MAND Kontrols focuses on helping customers save time, water, energy, and money.
