UNVENTED HOT WATER SYSTEMS
Unvented hot water cylinders have soared in popularity and can now be found in most homes across the UK. Connected directly to your mains water system, unvented cylinders ensure copious amounts of stored hot water is available on demand and they operate at mains pressure to offer much higher flow rates.
This allows you to enjoy improved shower and bath performance all year round!
WHAT IS AN UNVENTED HOT WATER SYSTEM?
An unvented hot water system has no cold water feed tank but instead has a sealed (unvented) hot water cylinder fed directly from the cold water mains, and uses mains pressure. The unvented cylinder maintains a pressure from an incoming water supply.Unvented systems are ‘sealed/closed’ systems and so require additional equipment, such as an expansion vessel to manage the changes in pressure within the system as the water within heats up.
