I'm pretty sure the best of these was made from chromed brass tubing.

Now I'm looking at electrically heated towel rails. I did think that
these were generally oil filled but it seems that most are made from
chromed steel tube and are water filled. Even with a rust inhibitor in
the water is this the best I can hope to find theses days?

Slightly surprised to hear this, but provided they are adequately sealed
it shouldn't matter.
