Ariston 65101719 Standard Expansion Vessel 7 Litre Aco 27 Mffi Nat Gas, Great deals on Ariston spares from Boiler Parts.
The Ariston Aco 27 Mffi Nat Gas expansion vessel is a unit to cope with the expansion of water in a home heating system or hot water system due to rises in temperature. When water rises in temperature this expands, particularly when it is kept under pressure such as in a sealed heating system or an unvented hot water cylinder. Expansion tanks typically contain a cylinder 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 just like those found on bicycle and car tyres is typically provided around the air side to allow the unit to be re-pressurised., Ariston Expansion Vessel Can be Delivered Next Working Day
