Instant S 15-1.5 Series PM pumps for domestic hot-water recirculation in single- and two-family houses are suitable for drinking water with a corrosion-resistant pump housing.

The pump is equipped with a high-efficiency permanent-magnet motor, with power consumption lowest to 5W.

The Instant S 15-1.5 pumps are designed for recirculation of domestic hot water in single- and two-family houses securing hot water instantly to all faucets. 

The pumps have a corrosion-resistant pump housing suitable for drinking water and are powered by a single-phase, high-efficiency ECM with permanent-magnet rotor. 

The Auto function adjusts the pump performance to actual system performance.

The unique Auto feature is saving up to 48 % heat energy and 97 % motor energy compared with a standard pump in continuous operation. Additionally, the pump can be set to temperature control mode and continuous operation 100 % for commissioning of the pump or 24 hours instant hot water.

The pumps are equipped with a flushing function which automatically circulates water to protect against bacterial growth in the pipes.
