Red face What electrodes to order

I have an old, oil boiler (domestic HW & heat) and I want to replace the electrodes. The metal ends, opposite the nozzle, take a 90 degree turn to connect to the transformer. I did not watch the technician last time the electrodes were installed so I don't know if the electrodes came with the 90 degree turn or it was something he had to fit. So what electrodes do I order? Thanx in advance.

Without the burner name or a pic of the electrodes and length it is hard to say. There are so many different ones out there. What I can tell you those 90 deg. copper pieces are removable. Just remove the nuts on the ends and they come off to put on the new ones or you can buy new ones if they are pitted but they do not come with the electrodes.


Go to above sight and scroll down until you come to the electrodes to see if this helps.

Hope this helps a little.
