camco 2500w ULWD vs LWD

Just checked with a multimeter and the ULWD element is slightly lower resistance than the LWD, 23.5 vs 24.8 fwiw.

Can you take a magnet to the base of each? Just to check if the ulwd is stainless or if it is plated (stainless should be much less magnetic than normal steel)

The base will rust. I have some of these and I am always careful to drain water out of the hlt or next time I brew there will be significant amounts of rust.

Just did the magnet test and both bases are magnetic with no noticeable difference between them.

I've also got the 2000w HWD element which has the same finish as the 2500w LWD element and its base rusted heaps with water in my HLT overnight. I've since added a chunk of aluminium as an attempt at an anode can't say if its fixed it since I haven't left water overnight.

Just to follow up now that I've used both, at about 230v the 2500 ULWD draws 9.7a (2230w), 2500 LWD draws 9.0a (2070w), and the 2000w HWD 7.5a (1700w).

So the ulwd is probably actually slightly higher density than the led.

And a aliexpress 2000w @220 draws 8.8a @230v (2024w).
