nitrogenpressure

The VEA expansion vessel has been designed to absorb the volumetric variations of the water in the system, due to the temperature increase. The system is kept at a certain air/nitrogen pressure, according to the operating pressure of the hot water or super-heated water boiler. It usually tops up the supply to super-heated water boilers. The VEA expansion vessel complies with the PED Directive 2014/68/EU.
