Why is an expansion tank necessary in heating systems?
Water expands when heated. Because water is practically incompressible and closed pipes have rigid walls, an expansion tank absorbs excess volume and prevents pressure surges.
Calculate heating and cooling system expansion vessel nominal volume (Vn) and pre-charge pressure according to EN 12828.
