High efficiency


Pumps make up 10% of the world's total electricity consumption, simply because most of them run inefficiently. With a Grundfos high efficiency solution, you will not only save your customers money, you will reduce their environmental footprint, as well.

ALPHA3: Efficiency is a balancing act

Very few heating systems are properly balanced. The result is inefficient operation. The new ALPHA3 and ALPHA Reader make it possible to do a flow-based hydronic balancing of any heating system – even underfloor heating – reducing your customers’ energy bills with up to 20%.

Energy efficient motors

Running on as little as 4W, the ALPHA series is your most efficient choice of domestic circulator. It offers the lowest EEI (energy efficiency index) of any comparable pump on the market, using 87% less energy than your average older circulator. This means another 10% of your customers’ energy bills.
