Just wondering

1-1.5 years. A friend had one that crapped-out and cooked the tank, killed everything. U can still use your old ones for making water.

 

I replaced my first titanium heater after almost 6 years use and it still looked like new. I was more concerned about the controller and temp sensor than the heater itself.

 

No, no copper.........

"Besides chromium, typical alloying elements are molybdenum, nickel and nitrogen. Nickel is mostly alloyed to improve the formability and ductility of stainless steel. Alloying these elements brings out different crystal structures to enable different properties in machining, forming, welding etc."

 

Why?

 

The clamp was out of the water, however, I found this;

3. Can stainless steel rust? Why? (I thought stainless did not rust!)

Answer: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface. If the iron is embedded in the surface, you can try a solution of 10% nitric and 2% hydrofluoric acid at room temperature or slightly heated. Wash area well with lots and lots of water after use. Commercially available "pickling paste" can also be used. See "The Care and Cleaning of Stainless Steel" for more information.

 

There are so many different grades of stainless steel its hard to describe it in general terms. Some are only slightly "stainless" while others are very resistant but get very brittle due to their alloy makeup.
