What's Included
The Vaillant uniSTOR PURE 90L Slimline Heat Pump Cylinder is a compact, high-efficiency hot water cylinder designed as one of the most space-efficient hot water cylinders for modern homes. Engineered for compatibility with Vaillant heat pumps, system boilers and open vent boilers, it provides consistent hot water with fast recovery times and excellent energy performance.
Its slimline design makes it ideal for properties where installation space is limited, without compromising on hot water capacity.
Designed for Heat Pump Efficiency
When installed alongside a Vaillant heat pump, the uniSTOR PURE delivers a highly efficient hot water solution. It is also compatible with all Vaillant heat pumps, system boilers and heat-only boilers, making it a flexible option for new installations or system upgrades.
The cylinder features a 1.85m² coil size, supporting efficient heat transfer and rapid recovery performance. With a 70% reheat time of just 7.39 minutes, it restores usable hot water quickly after demand.
Optimised Hot Water Performance
The cold water inlet plate is designed to minimise mixing between incoming cold water and stored hot water. This helps maintain usable hot water at the top of the cylinder, ensuring more available hot water for the household.
With a hot water capacity of 88 litres, the uniSTOR PURE 90L is well suited to smaller homes, apartments or properties with moderate hot water demand.
Compact Slimline Design
Measuring just 490mm in diameter and 990mm in height, the slimline format allows installation in tighter spaces such as cupboards or utility areas.
Despite its compact footprint, the cylinder delivers strong performance while maintaining manageable handling weight at 32.9kg net.
Energy Efficiency and Smart Control
The cylinder has a heat loss rating of 1.31kWh, helping to reduce standby energy waste and support efficient system operation.
When connected to compatible Vaillant systems, users can monitor and manage hot water demand via the myVaillant App, providing convenient control from anywhere.
