Why choose an unvented hot water cylinder?
Mains-pressure hot water to several outlets at once, with no cold water tank in the loft.
Unvented hot water systems are renowned for delivering excellent water pressure to all outlets. This makes them ideal for properties with multiple bathrooms or high-performance showers. Unlike traditional vented systems, they take their water supply directly from the mains. This direct feed eliminates the need for a cold water storage cistern in the loft and often simplifies pipework. As a result, it ensures consistently strong flow rates. Furthermore, because the system is sealed, the risk of contamination reduces. The system can also often be sited more flexibly within a property. World Heat Cylinders' expertise in unvented technology means we design every unit not only for performance and compliance but also for ease of installation and long-term reliability. Our commitment to using high-grade materials, like Duplex stainless steel, further enhances the durability and lifespan of our unvented hot water cylinders.
