The Home Booster unit incorporates an integrated 200 litre storage tank, providing a usable capacity of 180 litres and complete with a Type AB air gap in full compliance with Water Byelaws regulations. This design ensures secure separation from the mains supply while maintaining a reliable and protected water reserve.

A high-grade Stainless Steel pump is fitted as standard, delivering efficient performance, consistent pressure, extended service life and low-noise operation. For properties with increased demand, or where incoming mains pressure results in slow tank replenishment, an additional 180 litre slave storage tank can be specified to expand overall capacity and improve system resilience.

Supplied with a 2 Year Warranty.

The Grundfos Home Booster is a self-contained cold-water Booster Set is specifically developed to be used in properties or buildings where the existing mains water supply is insufficient to meet the standard pressurised hot and cold-water system demands.

For a slightly higher demand, or where the storage tank refills very slowly due to poor mains water pressure.

This product is the 180 litre extra storage tank for the home booster unit.

The Grundfos Home Booster sets can be used in conjunction with a 180L Slave Tank for applications requiring additional water supply.

The Slave Tank is compatible with the 3.0 Bar.
