Heating system equipment
Expansion vessels and pressurisation units in a large range of sizes for use with sealed heating and hot water systems.
When designing new commercial heating and hot water systems we advise customers to install a sealed system where possible. Improved efficiency and easier maintenance are just some of the benefits of using a sealed heating system.
You can read more about the differences between sealed and open heating systems here.
