Unvented Hot Water Systems

Unvented hot water systems work directly from the main water supply and are essentially, a storage cylinder for hot water. The water pressure and flow rate is much stronger than vented cylinders, because unvented systems have a direct feed from the mains supply of water – which makes it more hygienic too.

The features and benefits of an unvented hot water system include;

• Mains water pressure at your taps

• No need for a cold water storage tank

• Safety features and controls

• Fast reheat times

• Minimal heat loss

Typically, a 1st Call gas engineer can install, test and handover a fully-working unvented hot water system within one week.
