Warmflow Dual Cylinder Thermostat


Oil boiler control. Robust plastic housing consisting of control and limiter capillary thermostats.


  • Suitable for use with or without immersion pocket
  • Pre-wired internally for ease of installation

Control: a rise in temperature causes the expansion of liquid within the bulb and capillary.

The liquid acts on a bellows assembly within the plastic housing to open and close electrical contacts.

High limit: in case of abnormal rise in temperature, liquid expansion in the bulb and capillary of the dedicated safety limiter acts on a bellows assembly to open electrical contacts.

The limiter is manually resettable.
