AJS Developments Unvented Hot Water Heating System

AJS Developments - Staffordshire, Cheshire and Derbyshire

An Unvented Hot Water System gives the customer a hot water supply at mains water pressure.

Recovery time is very rapid, this means that a generous supply of mains pressure hot water is produced from a smaller hot water cylinder. The sealed system eliminates the need for roof storage tanks and its associated problems.

How it Works!

Unvented Hot Water Systems Installation

Is oil less friendly to the environment?

Because of the differences between unvented hot water storage systems and traditional vented hot water storage systems within the UK regarding the requirements for safety devices, it is essential that unvented systems comply with the Building Regulations and that installers are competent i.e. one holding a current Registered Operative card for the installation of unvented domestic hot water storage systems.

The requirements of the Building Regulations G3, state that all systems must be either:

• Approved by a member body or the European Organisation for Technical Approvals (EOTA) - operating a technical approvals scheme e.g. meeting the relevant requirements of G3.
• Approved by a certification body having National Accreditation of Certification Bodies (NACB) accreditation and testing to the requirements of an appropriate standard that will ensure that the requirements of Regulation G3 will be met e.g. BS 7206:1990,
• The subject of a proven independent assessment that will clearly demonstrate an equivalent level of verification and performance to a. or b. above.
