WaterBoost Nook WB-55 pressure boosting system

The WaterBoost Nook 55 Pop is a water pressure booster built for flats, apartments and anywhere the only space is a cupboard — a 55-litre WRAS-approved break tank with a DAB Esybox Pop variable-speed pump in front, delivering max 65 L/min and 3.2 bar max from a footprint that fits inside a kitchen unit. On a typical 8 L/min flat supply it runs a full-pressure 12 L/min shower for over 13 minutes. It’s the answer to the top-floor shower that dribbles, the combi that won’t fire, and the flat where a direct mains booster can’t legally deliver enough.

Suitable for heat pump systems. Gives an unvented hot water cylinder the pressure and flow it needs where the mains supply falls short.

Prebuilt with Byelaw 30 kit, ball valve, tank connector, service valve and insulation. Mains in, boosted out, plug in — no plant room, no loft, no landlord-scale works. DAB H2D app control. 5-year tank warranty, 3-year pump warranty.
