Kal, given so many people are having this issue it might be appropriate to recommend the anode by default rather than as an "if you have a problem" kind of scenario.

FWIW, we've sold many hundreds of heating elements (in both kit form and pre-assembled) last year and we rarely get any emails about it. Searching my emails for the word "rust" comes up with 4 customers who mentioned they saw rust.

I checked the numbers for those that purchased from Amazon using our links to built their own and the amount of heating elements sold is 12.0 times higher than the number of anodes. Only 8.3% of brewers who built their own also purchased anodes in 2013.

Maybe not the most scientific approach, but it appears to only be a small percentage of people that seem to have the issue. Recommending that everyone install the anode by default may be overkill, as you can always do it later.

Is there an Amazon link to purchase these all-stainless elements?

I have rust on both my camco elements. I just bought and am about to install all SS low density elements I bought from brew nation. They cost more for sure but I prefer this route rather than using an anode.

Mine was purchased through you (technically Mike@Spike). I updated my previous post with a picture (one page back).

So, I'm curious, if the BK element doesn't seem to be impacted that much, what's the reason? Is it the acids from the hops? Does it etch the face somehow to effectively provide a permanent barrier? If so, would it be practical to just go ahead and boil some hops in the HLT 1x/2x to get the same effect?

Some reaction in the boil probable passivates the metal ont he element that doesnt happen in the MLT. why not just passivate your elements pre-installation?

Im thinking that the element is coated copper but the base is whats rusting, not sure what thats made of might even be nickel alloy,

a thin layer of high heat silicone might be the easiest thing

Silicone tends to have solvents in it until cured, id be worried that would leech into the beer.

I used a food-grade silicon to seal a heating element in my old plastic HLT. That worked.

These are stainless steel elements with standard base after about 10 months of brewing - 26 brew sessions.

Kevin at Brewmation is the only one offering stainless steel elements with stainless steel elements that I could find.
I've replaced the elements in the above post with Brewmation elements.
I'll post a picture up of the Brewmation elements once I install, calibrate, brew, clean.

Both elements I received from Brewmation and High Gravity were APCOM elements. However, Brewmation orders a large special batch of elements that have stainless bases from APCOM.

I'd be curious for someone who doesn't have rust to list the manufacturer of the element, and to then disassemble their element connection and see what they find.

Just clean it, put a small coat of Dap all purpose silicone on the face of the base and put it back in, no worries!

I too had rust on both my HLT and BK heating elements. I bought and installed the Camco 11553 RV Magnesium Anode Rod. They are 1/2" just like the other bulkheads we have installed so familiar with the install procedure using the SS shims and silicon rings. I have no more rust issues.

+1 on the magnesium anode. I only installed it in my HLT, but it seems to be doing the trick for the most part. The key is to dry out the face of the element after you're done for the day I believe, and leave the lid off so the HLT can dry out completely.

Here are my new all stainless steel elements and kettle connections.
I left water in the boil kettle over night and no rust.
I am very happy with these alterations so far but I haven't ran through a complete brewing session yet.


Note: On the comments about the boil kettle element not rusting and having a dark patina.
My old element had this as well, but I took the element out of the kettle and saw rust under the patina and on the threads of the element base. See my other pictures above.
