Hi, my parents are going to install a 400w heated towel rail in their bathroom soon, I thought it would be a good idea to get an "energy regulator" fitted outside of the room, for the purpose of saving energy during the summer months etc.
Am I overlooking something, or are these just overpriced dimmer switches with a crude scale drawn on the front?
