The Vaillant uniSTOR heat pump cylinder range is designed to work seamlessly with Vaillant heat pumps, ensuring highly efficient heating and hot water systems. With a large surface area and smooth coil design, heat transfer is maximised, optimising the performance of connected Vaillant heat pumps and reducing running costs. Available in sizes ranging from 150 to 800 litres, uniSTOR heat pump cylinders come in both pre-plumbed (150-300 litres only) and standard options, providing flexibility for both you and your customers. Furthermore, the 250 and 300 litre cylinders have larger coils, making them compatible with a wider range of ground source heat pump systems. With thermal injected insulation and a 100% recyclable stainless steel tank, uniSTOR cylinders have a Global Warming Potential of less than 5 and offer a durable and sustainable heating solution.
