What it is
The Radiant 83644LP is a pipe expansion vessel from Radiant. Expansion vessels absorb the increase in water volume that occurs as a heating or hot water system warms up, helping to keep system pressure within safe limits.
Before you order
- Confirm the vessel is the correct type and connection for your system before fitting.
- Check the system's operating pressure and the vessel's rating to make sure they are compatible.
- Note the part number 83644LP and compare it against the existing component or the appliance documentation.
