Grundfos has released the Comfort PM Auto range of intelligent and energy-efficient hot water recirculation pumps. The company says the pumps eliminate the wait for hot water at showerheads and sink taps. Compared with conventional pumps that run continuously, company officials claim the Comfort PM Auto is capable of reducing energy costs by as much as 96% thanks to the Autoadapt feature, which ensures that the pump runs only when required.
The pump features three operating modes. In addition to Autoadap, which learns consumption patterns and then adapts to it, the pump also has temperature mode to keep the water temperature within an automatically detected range and 100% mode to allow the pump to run constantly at full speed.
For basic needs, Grundfos also offers the Comfort PM model, which is available with 100% mode. Both the Comfort PM and Comfort PM Auto are compact, provide silent operation, and can save as much as 12,000 gallons of water per year, according to the company.
