Tanks & Overflow

Q - Vented and Unvented Hot Water Cylinders - What's the Difference?

A - The main difference between vented and unvented hot water cylinders lies in their setup and operation. A vented system is open to the atmosphere and relies on a cold water storage tank, usually located in the loft, to feed the cylinder via gravity. These systems require a vent pipe for expansion and safety. An unvented system, on the other hand, is sealed and fed directly from the mains water supply.
