What it is
The Ariston 935184 is a regulation thermostat for the indirect side of an unvented or indirect hot water cylinder. It monitors cylinder temperature and signals the boiler to fire or stop, holding stored water at the set point. It is supplied by Ariston and is listed for a range of Ariston cylinder appliances fitted to gas boiler systems.
Signs this part needs replacing
- Stored hot water runs hotter or cooler than the set point on the cylinder control
- Cylinder reaches temperature but the boiler continues to fire, or stops firing too early
- Hot water temperature drifts or fluctuates between draws
- No response from the boiler when the cylinder calls for heat
- Erratic switching, with the boiler short-cycling on the cylinder circuit
Before you order
- Check the appliance data plate and confirm the model and serial number fall within the ranges listed above
- Confirm the old thermostat's part number markings match 935184
- Verify the thermostat is the indirect regulation type, not the direct or safety variant
- Isolate the power and water supply before removing the existing thermostat
