This British Standard specifies the strength and method of construction of calorifiers and storage vessels designed for central heating and hot water supply. It also specifies suitable safety devices and methods of pressure testing. The standard covers units with shells made from copper or carbon steel.
Reference is made to the protection from corrosion of carbon steel shells, by galvanizing, sealed zinc spraying or copper lining.
This standard covers calorifiers heated by steam, water, heat transfer fluid or electricity, but does not cover calorifiers with steam on the outside of the tube battery.
The information that the purchaser is recommended to supply to the manufacturer at the time of enquiry and order is given in Appendix A.
