What it is
A dual safety thermostat with an 18 inch capillary, supplied for use with vented immersion heaters. It combines the control and safety cut-out functions in a single unit, switching the immersion element off when the set temperature is reached and providing a separate overheat cut-out. It is listed for the Special Offers vented immersion heater range.
Signs this part needs replacing
- The immersion heater runs continuously and does not cut out at the set temperature
- The overheat cut-out trips repeatedly and the unit requires manual resetting
- Domestic hot water is consistently too hot or too cool against the thermostat setting
- The thermostat dial turns without any change in water temperature
- Visible damage, corrosion or a kinked capillary on the thermostat body
Before you order
- Confirm the appliance is a vented immersion heater, not a pressurised or unvented cylinder
- Check the existing thermostat's capillary length and mounting arrangement against the 18 inch unit
- Note the part number TS230 and compare it with the marking on the thermostat being replaced
- Isolate the electrical supply and drain the cylinder before fitting
