GRUNDFOS ALPHA2

From the jury's assessment

Heating pumps normally are the underdogs of building technology, but should get special attention as they are working nearly continuously. The Alpha 2 of Grundfos has been designed exactly for this purpose, offering optimal efficiency at the same time. A permanent-magnet-motor, a special coating of the housing and optimized hydraulics are the constructive ingredients for an optimal result. An AutoAdapt-function always measures how much power is needed, adapting the pump accordingly. The fully positive picture of the Grundfos pump is rounded by an attractive design for all this high technology.
