Description

This expansion vessel is a component for closed-loop heating systems. It is compatible with ACV Compact Condens 35, 55, and 65; ACV HeatMaster 71 and 101; and ACV Smart Line 85 and 130. The vessel maintains consistent pressure in the system by compensating for thermal expansion of water. This action protects boiler components from excessive stress and pressure.

Pressure protection	Protects boiler components from excessive stress and pressure
Primary function	Maintain consistent pressure in closed-loop heating systems
Thermal expansion compensation	Compensates for thermal expansion of water

Choosing and fitting

Expansion vessels are selected to match the boiler model and system volume. Before ordering a replacement, verify the boiler model nameplate and compare the part number. The vessel connects to the heating circuit via a connection point on the boiler; mounting position and orientation must follow the boiler installation manual. System pressure rating and pre-charge pressure of the replacement must match the original specification.

Signs of failure

Failure of an expansion vessel typically causes system pressure to rise uncontrollably or fluctuate during heating cycles. The boiler's pressure relief valve may vent water, or the system may lose pressure when cooled. A failed vessel may produce a hissing sound at the connection point or show signs of rust or corrosion on its surface.
