FAQ
Frequently Asked Questions
An unvented cylinder stores hot water at mains pressure, delivering stronger flow rates without the need for a cold water tank. Unlike vented (gravity) systems, unvented cylinders require safety devices such as expansion vessels and pressure relief valves and must be installed and commissioned to meet G3 Building Regulations.
