What it is
The Ferroli 39818220 is an automatic air vent for Ferroli gas boilers. It removes trapped air from the heating circuit to help maintain water circulation and prevent airlocks. The part is used across a range of Ferroli Divatech, Divatop and Domicompact appliances.
Signs this part needs replacing
- Water weeping or dripping from the vent body
- System pressure drops repeatedly with no visible leak elsewhere
- Gurgling or air noise from the boiler or radiators
- Radiators cold at the top while the boiler is running
- Boiler pressure gauge fluctuates or shows air in the system
Before you order
- Check the boiler model and part number against the fit list
- Confirm the existing vent is a Ferroli 39818220 or compatible fit
- Isolate the boiler and depressurise the heating system before replacement
- Check access to the vent location and any seals or connections
