Depxro Expansion Vessel

The Dexpro Delux expansion vessel allows the heated water in the tank to expand naturally. With unvented systems it is necessary to provide some space for the water to expand into. This is why the expansion vessel is required and must be fitted on the cold water inlet side for all unvented water heaters.
