The uniSTOR cylinder range has been designed to work in harmony with Vaillant heat pumps, to provide a complete heating and hot water system for specification into a range of developments.
Explore the range
uniSTOR's large surface area and smooth coil design maximises heat transfer, to ensure connected Vailllant heat pumps run at their optimum efficiency, to reduce running costs and increase hot water performance.
Ranging from 150 up to 800 litres, our uniSTOR heat pump cylinders are available in both pre-plumbed (150-300 litres only) and standard options, giving even more flexibility for specification. In addition to this, the 250 and 300 litre cylinders have an increased coil size making them compatible with a wider range of ground source heat pump systems.
uniSTOR cylinders also have a Global Warming Potential of less than 5 thanks to thermal injected insulation, as well as a 100% recyclable stainless steel tank with an ultra-hard-wearing outer shell, to deliver a highly efficient and sustainable heating system.
