The Ferroli company's thermocouple is an essential component for the proper operation of your boiler. This thermocouple monitors the flame during the combustion of the oil-air mixture, ensuring that the combustion process occurs safely. In case a flame is detected inside the boiler, the thermocouple automatically shuts off the boiler’s operation before the oil electromagnetically controlled valve opens, providing an additional safety feature to your heating system. It is compatible for use with burners, making it an essential accessory for central heating.
