What it is
The Vaillant 302497 is an 80 litre expansion vessel intended for use on solar thermal systems. It is listed by the manufacturer as a solar expansion vessel, marked /2, and is supplied as a sales item. Within a sealed solar circuit the vessel absorbs the volume change of the heat transfer fluid as it heats and cools, helping to keep circuit pressure stable.
Before you order
- Confirm the part number 302497 against the existing vessel or the appliance documentation.
- Check that an 80 litre capacity matches the system volume and the expansion requirement of the installation.
- Verify the connection size and system pressure rating required by the solar circuit before fitting.
- Consider whether the pre-charge pressure needs setting to suit the installation's static head and operating pressure.
