Engineered for both new builds and existing homes, Vaillant heat pumps combine cutting-edge technology and environmental responsibility, helping homeowners invest in sustainable comfort without compromising on efficiency or design
The Vaillant uniSTOR Heat Pump Cylinder is a durable, sustainable and highly efficient unvented hot water storage tank that is compatible with aroTHERM Plus Heat Pump systems. This high performance cylinder ensures your heat pump operates at full potential with low environmental impact, providing hot water storage and keeping water hot, so you have a reliable supply of hot water for taps, showers and baths.
Its smooth, large-surface-area internal coil efficiently transfers the lower-temperature heat produced by the pump into stored hot water, enabling faster heat transfer and improved efficiency. Because heat pumps operate at lower flow temperatures than boilers, this design is essential to ensure the hot water heats up quickly and stays consistently warm, while minimising energy use at the same time.
Ideal for new builds or retrofit installations focused on carbon reduction, the heat pump cylinder design ensures shorter reheat times, enhanced hot water performance and lower running costs. Made from 100% recyclable stainless steel, the Vaillant uniSTOR features high-performance injected thermal insulation with a Global Warming Potential (GWP) of less than 5, combining minimal heat loss with exceptional eco-friendly credentials.
