The Vaillant Ecotec Plus 438 Vu 386 expansion vessel is a device to handle the expansion of water in a heating system or hot water system due to increases in temperature. When water increases in temperature it expands, in particular when it is stored under pressure such as in a sealed heating system or an unvented hot water cylinder. Expansion vessels typically consist of a storage container or disc which is divided inside into two compartments separated with a rubber sheet, known as the diaphragm. Inside the expansion vessels there is water on one side of the diaphragm and air or an inert gas such as nitrogen under pressure on the other side. An air valve similar to those found on bike and car tyres is typically provided around the air side to allow the system to be re-pressurised., Vaillant Expansion Vessel Can be Delivered Next Working Day
