Stiefel’s aftermarket repair parts restore burner functionality to original equipment manufacturer (OEM) standards. Platinum electrodes zundelemente retain ignition sparking for more than 10,000 cycles, and ceramic-coated nozzles resist erosion by high-sulfur gas. For a London-based hotel, our replacement OEM solenoid valves limited leakages from monthly to yearly, reducing maintenance costs by £8,000. Essential components such as flame sensors and fuel filters must ship the same day while detailed troubleshooting manuals do as well.
