D'MAND hot water pumping system

Taco's D'MAND hot water recirculation pumping system in three models 660, 008 and 0011, has been designed to supply hot water on demand in homes from 600 sq.ft. to 15, 000 sq. ft. D'MAND systems conserve both water and energy in water-heating systems by returning cooled water in the hot water pipe back to the water heater through the cold water line. The system operates only when there is a demand for hot water. A thermal sensor controls system operations by turning off when a preset rise in temperature occurs.
