Can an electric towel radiator be installed anywhere or are they dependent on a water supply? I’m thinking of putting one on the landing as our current bathroom is falling apart and we are frantically saving up to replace it. So I don’t really want to waste time and money putting in a new radiator by a plumber hence my idea for a smallish electric towel radiator on the landing which we can use to dry towels after showering. We recently stayed in a holiday cottage that had some which were on most of the time at a low temperature but they were brilliant at drying the whole family’s towels.
