It is a little known fact that the majority of heat generated by

It is convected.

It is another little known fact that heating things does not dry them.
It is heating the air moving past them so that it can carry away the
moisture, that dries them.

It does 3 things
1. It lowers the RH of the air, since maximum absolute water vapour content rises a lot with increasing temp. Ie it dries the air
2. It causes the air to move past the wet thing
3. Higher temp also increases rate of evaporation


Now apply those facts to towel rails..

If what you really want is towel drying, a small fan is far more effective, and not a total waste in summer.
