What it is
The Ideal 177540 is an expansion vessel kit supplied for Ideal domestic boilers. The expansion vessel absorbs the volume change in the sealed heating circuit as the water heats and cools, holding system pressure within the range the boiler expects. This kit is the version specified for i-mini, Independent and Code Combi appliances built from ABK onwards.
Signs this part needs replacing
- System pressure climbs steadily as the boiler heats up and falls again once it cools.
- The pressure relief valve discharges water, often leaving a trace from the discharge pipe.
- The boiler needs frequent topping up to keep the pressure gauge in the normal band.
- Pressure rises quickly from cold to hot, or the gauge reads high before the boiler has run.
- Water is visible around the vessel connection or the vessel feels heavy when disconnected.
Before you order
- Confirm the appliance model and that it is an ABK onwards build before ordering.
- Check the part number on the existing component or in the appliance documentation against 177540.
- Inspect the vessel connection and any seal at the same time, as these are disturbed during replacement.
- Work on the boiler casing and water circuit should be carried out by a competent person.
