DAB Esybox
Esybox EsyTwin Booster Set 60160491 (now code 70250049)
- Established 1975
- Trusted by thousands of customers
The DAB Esybox EsyTwin 70250049 combines two full-size Esybox variable speed pumps on a single Esytwin docking base, delivering a combined flow of up to 180 l/min at 65m head. Designed for large properties, apartment blocks, and commercial applications where a single pump cannot meet peak demand — or where built-in redundancy is essential. Backed by a 3-year DAB manufacturer warranty.
The two pumps communicate wirelessly — sharing load under high demand, alternating to distribute wear evenly, and automatically switching to single-pump operation if one unit develops a fault. This means water supply is never fully interrupted, even during a pump fault. Each pump includes a built-in inverter, 2-litre expansion vessel, orientable LCD display, and WiFi connectivity via the DAB H2D app, with Google Home and Amazon Alexa voice control.
WRAS approved for potable water. Self-primes to 8m. Expandable to 4 pumps using two Esytwin bases. 3-year DAB warranty. Note: must be fed from a break tank — direct mains connection is not permitted.

More about this product
The DAB Esybox EsyTwin is a complete twin-pump booster set combining two DAB Esybox variable speed pumps on a single Esytwin docking base. It is the natural step up from a single Esybox where higher flow rates, greater reliability, or built-in redundancy are required.
The two pumps work together intelligently — sharing load under high demand, alternating to distribute wear evenly, and automatically switching to single-pump operation if one unit develops a fault. This means water supply is never fully interrupted, even during a pump fault.
Combined, the twin system delivers up to 180 l/min at 65m head, making it suited to large properties, apartment blocks, commercial buildings, and high-demand agricultural or irrigation applications. Backed by a 3-year DAB manufacturer warranty.

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.
