Expansion Vessel Kits

Sealed heating systems need expansion vessel kits to absorb the volume changes that occur as water heats and cools, keeping pressure within safe limits. These kits combine the vessel itself with the brackets, valves and pipework needed for straightforward installation on both heating and potable circuits. Options range from compact units for smaller systems to larger wall-mounted models, with potable versions featuring corrosion-resistant liners.
