Expansion vessels for boilers provide the essential pressure management capability that protects your heating system from thermal expansion damage. These specialized components create a controlled space for water volume changes that occur during normal heating cycles.

The durable boiler expansion vessels in our catalog combine robust construction with precision engineering to deliver reliable performance throughout years of service. Unlike basic pressure tanks, these vessels incorporate engineered diaphragms specifically designed for the temperature ranges and cyclic operation typical in heating applications.

Our selection of reliable heating system expansion solutions offers:

• Properly sized options for various system volumes
• Pre-charged designs for simplified installation
• Corrosion-resistant materials for extended service life
• Space-efficient configurations for challenging installation locations

For system designers and maintenance professionals, these vessels provide the necessary buffer against pressure spikes that can damage expensive components or trigger relief valve discharge.
