What it is

The Oso Hotwater 80030 Thermostat Surface Mounted is a surface-mounted thermostat used on hot water cylinders. It is listed by the manufacturer under the Popular Cylinder spares range for cold water inlet controls. The thermostat regulates the stored water temperature in the cylinder it is fitted to.

Signs this part needs replacing

  • Domestic hot water runs consistently hotter or cooler than the set temperature
  • Cylinder temperature fluctuates or drifts without any adjustment to the control
  • Hot water fails to reach temperature, or the cylinder overheats
  • The overheat cut-out trips repeatedly and requires manual reset
  • The thermostat no longer responds to adjustment of the cylinder control

Before you order

  • Confirm the cylinder model against the fit list above, as the thermostat is listed only for those appliances
  • Check the existing thermostat is a surface-mounted type and that the mounting arrangement matches
  • Verify the part number 80030 on the existing thermostat or in the cylinder documentation
  • Confirm whether the work should be carried out by a competent heating engineer, as cylinder controls involve stored hot water and electrical connections
