What it is
The Viessmann 7823182 is a water expansion vessel carrying manufacturer part number 7823182. It is a pressure vessel used in sealed heating systems to accommodate the change in system water volume as the water heats and cools. Without a vessel of this type, the resulting pressure rise across a sealed system would be taken up by the safety valve.
Before you order
- Confirm the part number 7823182 against the appliance data plate, manual or existing component before ordering.
- Establish the connection size, vessel capacity and pre-charge pressure the installation requires, as these are not listed in the supplied information.
- Check that the vessel itself is the cause of the pressure fault; a discharge from the safety valve or repeated pressure loss can also come from a failed filling loop, a blocked expansion pipe or an incorrectly charged system.
- Verify the vessel will physically fit the available space and that the connection will align with the existing pipework.
