About Unvented Cylinders
Built with safety features and insulated for maximum energy efficiency, unvented cylinders are the perfect choice for modern households seeking consistent, high-pressure hot water and a streamlined, low-maintenance system.
Unvented Cylinders
Unvented hot water cylinders provide high-performance, mains-pressure hot water for powerful showers, fast-filling baths, and reliable water flow throughout your home. Unlike vented systems, they don’t require a cold water storage tank, saving space and allowing flexible installation—even in homes without a loft.
