    Product description

    The Grundfos Alpha1 25-60/180, a circulation pump in the latest Grundfos Alpha series, has been designed for domestic heating systems, central heating, and underfloor heating. By means of the latest technologies, this circulation pump saves considerably more energy than the older Grundfos models. The central heating pump has a user-friendly operating panel with one button to operate the entire device, and a display showing the actual power consumption in watts.

    Setting the Grundfos Alpha1

    The pump has the following settings:

    • Proportional-pressure curve: PP1 (= lowest setting)
    • Proportional pressure curve: PP2 (= highest setting)
    • Constant-pressure curve: CP1 (= lowest setting)
    • Constant-pressure curve: CP2 (= highest setting)
    • Constant curve/constant speed I (= lowest setting)
    • Constant curve/constant speed II (= intermediate setting)
    • Constant curve/constant speed III (= highest setting)

    Which pump setting for which situation?

    The selected setting depends on your personal situation.

    • Only radiators: proportional pressure (PP1 or PP2)
    • Underfloor heating or underfloor heating + radiators: constant pressure (CP1 or CP2)
    • No regulation, like the old pump with three settings: constant speed (settings I, II, and III)

    Whether the high or low setting should be used depends on the capacity required for your system, which differs on the basis of the environment.
