What it is
The Stuart SPU 235 MIDI is a pressurisation unit manufactured by Stuart Turner. It is designed to hold and top up pressure in sealed heating systems, replacing lost water automatically rather than relying on manual filling. The unit sits within the Stuart Turner SPU range and is listed here under the MIDI designation.
Signs this part needs replacing
- System pressure falls repeatedly and the unit fails to restore it
- The unit runs continuously, or runs without bringing pressure back to the set level
- Visible water loss or weeping from the unit body or connections
- Unusual noise from the pump or motor during operation
- Fault or warning indication on the unit's control panel
Before you order
- Confirm the existing unit is marked SPU 235 MIDI so the model matches
- Check the system pressure gauge reading against the unit's set point before condemning it
- Verify there is no leak elsewhere in the sealed system causing pressure loss
- Confirm the electrical supply and available space match the existing installation
