Description

EXPANSION VESSEL

Expansion vessels  are installed on sealed systems to allow for the 4% expansion in water as the system heats up and therefore protect from excessive pressure

How it works

 

The expansion vessel allows for the take of expansion of water within its membrane casing, as when water temperature increases the membrane inside the vessel inflates to allow the water to fill the vessel. The membrane will continue to expand until the system reaches its maximum temperature. Once this has been reached the membrane will be fully inflated and takes up the capacity of the vessel shell. Gradually the temperature will drop, which will in turn decrease the volume of water. Due to the pressure from the pressurised air surrounding the membrane, water will start to exit the vessel until the membrane is deflated.

 

Material

Body: Cold Pressed Carbon Steel

Water Connection: Steel

Membrane: Synthetic Butyl Rubber

Installation

The expansion vessel is ideally sited either on the return leg of a central heating circuit,

although installation on the flow is also possible if sited on the suction side of the system

circulating pump.
