Unvented hot water system

For many years domestic plumbing practices in the United Kingdom have relied on cold storage tanks in the loft and a hot water cyclinder.

Unvented hot water cylinders have been approved and installed since the late 1980’s and have many benefits to the end user, specifiers, developers and installers.

Benefits

• True power shower performance without the pump
• No tanks in the loft, no risk of water stagnation and Legionella
• No risk of frost damage to pipework and tank filling noise
• Simple plumbing design uses less pipework, saving time and money
• Wholesome water to all cold taps
• Mains pressure giving good shower flow and force, no shower pumps
• Balanced hot and cold water supply pressures giving wider choice of taps  and mixers
• Faster recovery rates compared to older cylinders
