WaterBoost WB – Advant slim 2000 Esybox 2602B110SL

The WaterBoost WB-Advant Slim 2000 Esybox combines two 1000-litre WRAS-approved UK-manufactured slimline tanks (each 600mm W × 1250mm L × 1703mm H) linked together for a 2000-litre storage buffer, paired with the DAB Esybox external variable speed pump — delivering 80 l/min at 3 bar and up to 6.5 bar maximum, with WiFi, DConnect app, H2D technology, Google Home and Alexa voice control.

Both tanks are just 600mm wide — so each passes through a standard doorway with 162mm to spare. That gives you 2000L of storage in installations no standard-footprint 2000L tank can reach, with flexible arrangement options: side-by-side, end-to-end, or even in separate rooms linked by pipework. The Esybox sits alongside the tanks for full pump accessibility, running at an exceptionally quiet 43 dB(A). All interconnecting pipework included, tank-to-tank connection kit supplied — no site fabrication required.

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