When water rises in temperature that expands, particularly when it is placed under pressure such as in a sealed heating system or an unvented hot water cylinder. Expansion tanks 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 vessel 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 comparable to those found on bike and car tyres is typically provided for the air side to allow the system to be re-pressurised., Ariston Expansion Vessel Are Dispatched Same Day, For Next Day Delivery
