Back to the top Product Description

The Grundfos Home Booster is a self-contained cold water booster set, designed for domestic properties where the existing mains water supply is insufficient to meet the demand requirements of pressurised hot and cold water systems. The Home Booster is suitable for most domestic properties with one or two standard bathrooms with standard fittings, or en-suite, and cloakroom, plus other normal household appliances.

The unit features an integral 200 litre storage tank with Type AB air gap, in accordance with Water Byelaws regulations. The high quality stainless steel pump delivers high efficiency, sustained performance, long working life and quiet operation. The Grundfos PM2 controller on/off controls the pump, and also provides dry run protection should the storage tank run out of water.

Installation is straight forward requiring connection of mains cold water supply, discharge pipe, overflow pipe and electrical connections.

  • Electronically on/off controlled
  • Nominal performance 3.0 bar or 4.5 bar at 0.5 l/s (depending on model)
