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.

See our full range of pressurisation units and expansion vessels matched for use with Hamworthy commercial boilers.

Boiler controls and system cleaning

As well as energy efficient commercial boilers and water heaters we also supply equipment to enhance the efficiency and longevity of your heating system.
Heating controls are a vital element of your commercial heating system. For multiple boiler installations a good boiler sequencer will help maximise the benefits of the commercial boiler plant.

As commercial heating experts, we recommend maintaining a clean and protected heating circuit to improve the life of your system and protect new boilers. We offer dosing pots for introducing chemicals to the system as well as air and dirt separators.
