Thanks for all the responses.
I tend to be cautious about the electric models -- electric heat is simply a controlled short. Also it is a plug in appliance with a life span, I'll eventually end up with some funny holes in the wall where it was mounted.
A hot water system on the other hand is completely passive. Now, if it isn't effective I'll want to reconsider the electric models.
Actually my interest in the "towel warmer" is more practical than comfort. We live where it can be rather damp and towels left on the rack go "bad" rather quickly if hung up damp. We are presently throwing them in the dryer after each use. This is a bother and an expense I'd like to eliminate. Having the towels heated after the shower is the goal.
I have read some of the consumer reviews, etc for the electric models. There are some complaints of singed towels and electric models going over to the dark side.
So, I'd like to hear about any recommended models.
It is true that lacquer can deteriorate with heat and moisture. The present towel rack from 1979
still has its finish intact, I presume it is a lacquer-based finish.
I had thought about having it chrome plated.
