When it comes to boiler repairs and replacements, having the right parts is essential. That’s why we offer a wide selection of boiler electrodes designed to fit different models and systems. 

Ignition electrodes are essential for igniting the burner in gas and oil boilers. Built to perform, these components ensure reliable start-ups for heating systems. 

Sometimes called flame detection probes, ionisation electrodes play a key role in maintaining safety during boiler operation. If the flame is lost, these components ensure the system shuts down properly. 

Heat-detection leads include an ignition electrode to generate the spark to ignite the burner and a flame-detecting electrode that ensures the presence of a flame. Having both in a single package helps reduce potential hazards and ensure reliably safe performance.

NTC probes are critical for precise temperature control. Designed for accuracy and reliability, these probes help regulate boiler performance and improve energy efficiency.
