I have some water heaters with heavy useage. The well water quality is good by tests and within norms.
I have used several brands of elements, usually 3500 and 4500 watt, of all density types. I used to get about 2 or 3 years + from an element. Lately, I am changing elements like batteries in a kids toy.
Heaters are drained regularly and I recently vacuumed out the calcium debri in the bottom of one. Installed a Camco mfg. lime life ripple super low watt density element. Blew out at one of the sharp bends in 2 months. Looks like the metal was stretched too thin there. Almost no calcium-lime build up on the element. Quiet in operation. Another went zonkers and blew out in a few areas and bent itself up into a pretzel.
NO dry firing. A mediuim density fold back element also blew in 6 months.
Do anode rods protect the heating element as well as the tank? Any ideas?
