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.

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.

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.
