What Is an Unvented Hot Water Cylinder?

An unvented hot water cylinder stores hot water under mains pressure, delivering strong and consistent water flow to your taps, showers, and bathrooms without requiring a cold water storage tank in the loft.

Unlike traditional vented systems, unvented cylinders provide higher water pressure, improved hot water performance, and greater energy efficiency, making them an excellent choice for modern homes and properties with multiple bathrooms.
