WaterBoost WB – Advant 2000 slim Esybox Twin 2602B410SL

The WaterBoost WB-Advant Slim 2000 Esybox Twin is the flagship of the Slim range — combining two 1000-litre WRAS-approved UK-manufactured slimline tanks (each 600mm W × 1250mm L × 1703mm H) with two DAB Esybox pumps in a coordinated Duty/Assist configuration. Delivers 140 l/min at 3 bar combined, up to 6.5 bar maximum, with H2D wireless load balancing, WiFi, DConnect app, Google Home and Alexa voice control.

Both tanks are just 600mm wide — each passes through a standard doorway with 162mm to spare, giving you 2000L of storage and dual-pump redundancy in installations no standard-footprint tank can reach. Install the tanks side-by-side, end-to-end, or in separate rooms linked by pipework. The two Esybox pumps communicate wirelessly via H2D technology — balancing load, engaging together at peak demand, and providing true duty/standby operation. Both run at 43 dB(A) each. Stainless steel twin-pump frame and all interconnecting pipework included.

Each UK-manufactured tank carries an outstanding 10-year warranty and each DAB Esybox a 3-year warranty. Delivery is typically 1–2 working days.
