What it is
The Vaillant 181061 is a 6 litre expansion vessel for Vaillant gas boilers. It absorbs the expansion of heating water as the system heats up, holding system pressure steady and protecting the boiler and its components from over-pressure. It is fitted across the Thermocompact, Turbomax Plus and Turbomax Pro ranges.
Signs this part needs replacing
- System pressure climbs sharply when the boiler is running and falls again once it cools
- Pressure gauge reads high with no visible leak on the system
- Water discharging from the pressure relief valve during heating cycles
- System pressure needs topping up repeatedly
- Vessel feels heavy or sounds full of water when tapped, indicating a failed diaphragm
Before you order
- Check the model and GC number on the boiler data badge against the fit list
- Confirm the existing vessel's capacity and connection before removal
- Depressurise and drain the boiler before removing the old vessel
