How it compares

Three 80 l/min boosting systems in the 450–500L range. The WB-Advant 500 Esybox leads on value — cheapest of the three, most storage, WRAS confirmed, 6.5 bar max, WiFi and H2D, and an outstanding 10-year tank warranty.

Which should I choose?
WB-Advant 500 Esybox — the best-value choice at £1,210 + VAT. Cheapest of the three, most storage (500L), same DAB Esybox pump as the Esytank, 6.5 bar max, 43 dB(A), WiFi and H2D, WRAS confirmed, and an outstanding 10-year tank warranty. 1–2 day delivery. The right choice for the large majority of potable water boosting applications.
Powertank SLIMLINE 450 Variable — choose for Fluid Category 4 compliance, or specifically if you need the upright slimline format. 450L, 80 l/min, 5 bar max, 8L pressure vessel, no WiFi. £1,345 + VAT.
DAB Esybox with Esytank — the same Esybox pump in the DAB-designed Esytank system (480L useable). Choose if you specifically want the DAB Esytank ecosystem — particularly to add further Esytank storage via the coupling kit. WRAS status not stated on product page. £1,380 + VAT.

Frequently asked questions

How much does it cost and how quickly is it delivered?

£1,210.00 + VAT (£1,452.00 inc VAT). Delivery is typically 1–2 working days. Contact us via WhatsApp or phone to confirm availability before ordering.

What is the Advant tank and how does it differ from a slimline?

The Advant tank is a UK-manufactured, 100% rust-proof WRAS-approved tank in a wider format (650mm W × 870mm L × 1200mm H) rather than the tall narrow cylinder of a slimline. It carries a 10-year warranty — twice the 5 years offered on slimline formats. The Advant format suits garages, plant rooms, and spaces where a wider, lower-profile installation is more practical. Note: the 870mm length means it requires more depth than a slimline cylinder.

What is the difference between this and the WB-Advant 500 Mini3?

Both use the same 500L Advant tank with 10-year warranty. The pump differs. The WB-Advant 500 Mini3 (£896 + VAT) uses the Esybox Mini3 — 50 l/min @ 3 bar, 5.5 bar max, 45 dB(A). This system uses the full Esybox — 80 l/min @ 3 bar, 6.5 bar max, 43 dB(A), H2D technology. Choose the Mini3 if 50 l/min is sufficient; choose this system for higher flow and pressure requirements.

How does the mains connection work?

The mains supply connects directly to the tank via the pre-fitted ¾” ball float valve. The tank fills automatically. The Esybox draws from the tank via the included PVC pipework and boosts pressure throughout the property. A minimum of 0.5 bar incoming pressure is required.

Is there a 1000L version?

Yes — the WB-Advant 1000 Esybox (£1,360 + VAT) provides 1000L storage with the same DAB Esybox pump. For very high-capacity or commercial requirements, the WB-Advant 1000 Esybox Twin (£2,461 + VAT) features two Esybox pumps for maximum redundancy and performance.

What warranties are included?

10 years on the WRAS Advant tank and 3 years DAB warranty on the Esybox pump, when purchased from Anglian Pumping Services.
