- Established 1975
- Trusted by thousands of customers
The 300 litre WaterBoost “Slimline EXT” system, featuring a DAB Esybox external variable speed pump, has been engineered to provide a high-performance yet cost-effective solution for properties experiencing low water pressure or restricted flow.
Ideal for customers looking to reduce installation costs while still investing in an energy-efficient, high-quality boosting solution, the Slimline EXT delivers exceptional reliability and consistent household performance.
The external variable speed pump is designed to sit neatly alongside the storage tank, ensuring a clean and compact installation while allowing easy access for servicing and maintenance.
Capable of delivering up to 80 litres per minute at 3 bar, the Slimline EXT provides strong, consistent pressure and flow — making it an excellent choice for properties with demanding water usage.
With compact dimensions of just 600mm wide and 1200mm high, the tank is designed to pass through a standard doorway and is supplied fully pre-built and ready to install, eliminating the need for on-site assembly. This makes it highly suitable for both new and existing properties, allowing installation under stairs, in garages, or within utility rooms.
The Slimline range is ideally suited to 3–4 bedroom homes, particularly where water pressure is poor and available floor space is limited, delivering a discreet yet powerful boosting solution without compromise.
