Overview:

The Niagara range of pump is the entry level model from Grundfos. They come in two versions; the 1.5 bar pump and the 2.0 bar pump (relating to their outlet pressure) Both are twin impeller so they can pump both hot and cold water. The 1.5 bar model will comfortably supply one standard shower only, whereas the 2.0 bar will only supply no more than two standard showers.
