WaterBoost Nook
The WaterBoost Nook range is made for flats, apartments and smaller homes with one or two showers — the properties where a full-size tank system won't fit and the only space is a kitchen unit or a cupboard. Each Nook pairs a compact WRAS-approved Polytank with a DAB Esybox Pop variable-speed pump on a single base, prebuilt and ready to connect.
A break tank is the legal way to boost above the 12 L/min direct-mains limit. The Nook fills from your own supply after the stopcock and delivers max 65 L/min at 3.2 bar — enough for a proper shower on a top floor, a combi that fires every time, and nothing to ask the freeholder. On a typical 8 L/min flat supply the Nook 55 runs a full-pressure shower for over 13 minutes.
Byelaw 30 kit, ball valve, connectors and insulation are fitted before delivery. DAB H2D app control. 5-year tank warranty, 3-year pump warranty. Delivery typically 1–2 working days.

What is a water booster pump?
A water booster pump increases the pressure of an existing water supply to give stronger flow at taps, showers and appliances. It can be a small inline pump fitted to the incoming mains, or a larger pump and tank set that draws from a break tank to feed the whole house. Boosters do not create water – they raise the pressure of the water already coming in.
What is the difference between an inline booster and a tank-and-pump booster?
An inline booster connects straight onto the incoming mains and is limited to 12 litres per minute under UK water regulations – examples include the Salamander HomeBoost and WaterBoost WB-Compact. A tank-and-pump booster, such as the Grundfos Home Booster or DAB Esybox with Esytank, draws from a break tank and can deliver much higher flow rates for larger homes with multiple bathrooms.
What is a variable speed booster pump?
A variable speed booster uses an inverter to adjust pump speed in real time to match demand. It maintains constant pressure as outlets open and close, runs more quietly than a fixed-speed pump and typically saves up to 50 per cent of the energy a fixed-speed equivalent would use. The DAB Esybox, DAB Esybox Mini 3 and Grundfos Scala2 are common variable speed examples.
