Expansion Pressure Vessels
Pressurised closed systems on either heating, hot water or chilled water systems may include Expansion Pressure Vessels. They come in various sizes from 2 litre to 2000 litre and they play an important roll within any heating or hot water system.
Some vessels fall within the Pressure Systems Safety Regulations 2000 (PSSR) covering the safe design and use of pressure systems. The stored energy within pressure vessels means they should be regularly inspected and maintained. This should form part of your written scheme of examination which is a legal requirement in some instances.
