Grundfos ALPHA2 are popular electronically controlled circulation pumps designed to replace older, energy-intensive pumps in heating systems of family houses and apartments. They automatically adjust their output to the system's current demand.
The range includes pumps in various installation lengths (130 and 180 mm) and versions - from basic models up to variants with an air separation chamber. Further down in the category you will find a more detailed breakdown by length and type.
Frequently Asked Questions
- How do I find out the length of the original pump? Measure the distance between the two threads/flanges on the pipe - it is most often 130 or 180 mm.
- Is it worth replacing the pump with an electronically controlled one? Yes, the ALPHA2 uses significantly less electricity than older fixed-speed pumps, and the investment usually pays back within a few years.
- What is a pump with an air separation chamber? A special design that makes it easier to vent the system, suitable for installations with a larger amount of air in the system.
