Abstract
Reviews the application and design of systems using sealed expansion vessels from circa 1967 to the present day, incorporating all types of systems. Discusses the fundamental differences and characteristics between open vented and sealed expansion vessel systems, and also the attitudes of water authorities to both commercial and domestic systems. Compares this with other western countries. Investigates whether there have been any inherent disadvantages of using sealed systems and concludes by considering current appropriate British standards and codes of practice together with the terminology used in some instances, which tend to create unfavourable impressions of sealed systems.
