WaterBoost WB – Advant slim 1000 variable speed 2601B310SL

The WaterBoost WB-Advant Slim 1000 Variable Speed is a large-capacity, self-contained slimline boosting system for high-demand domestic and light commercial properties with restricted plant room access. A 1000-litre WRAS-approved UK-manufactured Advant Slim baffled Enduromax tank (600mm W × 1250mm L × 1703mm H) houses the DAB Esybox Diver — a fully integrated variable-speed pump that sits submerged inside the tank — delivering up to 100 l/min at 5 bar maximum pressure, with WiFi and DConnect app.

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

At just 600mm wide, the vertical baffled slimline tank passes through a standard doorway. With the pump housed inside the tank, there’s no external unit to accommodate alongside it — a single-object install that gives you 1000L of storage in installations no standard-footprint tank can reach.
