For Residential and Light Commercial Heating SystemsA typical pump in a heating system runs at full speed day and night. The stainless steel ALPHA from Grundfos adapts to the variable demand of the house while keeping your comfort. In that way it saves a considerable amount of electricity and thereby reduces an equally large amount of emissions. Rated A for its energy efficiency, the ALPHA is a highly reliable and environmentally responsible choice. When installed and set in the unique Grundfos AUTOADAPT function ALPHA will analyze and adjust automatically to your heating demands. This pump is comparable in size to Taco 007 and Bell & Gossett NRF-22 pumps. ALPHA is the latest and most innovative member of the Grundfos family of high-quality circulators.
