Worcester Thermocouples are fitted to boilers that have a permanent pilot light, they are an early way of detecting if there is a flame present as well as retaining the gas valve open. This is achieved when the thermocouple is heated by the pilot light flame which in turn sends a small electrical current to the gas valve.
