The Importance of Ventilation for Heat Producing Appliances

Carbon Monoxide (CO) is an extremely poisonous and deadly gas that has no odour, taste or colour. Heat producing appliances such as stoves, fires and boilers all have the ability to produce carbon monoxide at dangerous levels if they are poorly fitted, are not regularly serviced or have insufficient/restricted ventilation.  It is vital that heat producing appliances have adequate ventilation as stipulated by building regulations.

Each year up to 50 people die needlessly from carbon monoxide poisoning and many more suffer serious health problems due to unnecessary exposure.

If you intend having a solid fuel stove installed it is vital that you use a HETAS approved installer and fit an audible CO alarm.  HETAS installers MUST comply with current Building Regulations when installing your product to stay approved.

HETAS states “Customers using a HETAS Registered Installer will be given a HETAS Certificate of Compliance by the installer on the completion of installation work.  This is vital importance in demonstrating that the installation was carried out by a competent installer working for a HETAS registered business and complies with the relevant Building Regulations.

A requirement for continued HETAS Registration is that the work of Registrants must be safe and comply with relevant Building Regulations, Approved Documents, British Standards and general Regulations as applicable to the region or country where the work is carried out.

If the work of the Registrant you employed falls below these standards, HETAS will ask that the Registrant concerned returns to put right any defects and to ensure relevant standards are achieved.  HETAS have a complaints process that in some cases of poor performance can result in disciplinary proceedings.”

REMEMBER! Poor Ventilation Can KILL!  On this subject HETAS states “Ventilators must comply with Building Regulations.  This is normally achieved through BBA certification to ensure that they meet the applicable aspects of the relevant approved documents of the building regulations. The equivalent free area must always be specified by the manufacturer.  This value is determined using a dynamic test method that has been developed by Advantica Technology and referenced in BS 5440: Part 2: 2000.  The equivalent free area must be given in an unambiguous manner where it can easily be read.  It is only this equivalent free area that should be used when specifying the required sizes of ventilators.”

Full HETAS guidelines can be found in the current HETAS Guide
