Given how easy it is to waste energy by leaving a heated towel rail on for too long, because it is upstairs and you are now downstairs until you go to bed, I think every heated towel rail should have one of these as standard.
Although I am very happy with the performance of the product, it only got three stars for two reasons.
Firstly, the wiring in was tricky because of the terminal sizes compared to the twin and earth cabling.
Secondly, if used in a location, other than brightly lit and at light switch level, the LCD readout is not that easy to see and actually requires the use of a torch whilst sat on the floor.
It was also disappointing to see that the wiring diagram inaccurate. The installation instructions contain a sketch of wiring for a low voltage installation, but a wiring diagram for a mains voltage circuit. This has been corrected on the website, but obviously not in shelf stock items. Suppliers should be given a correction sheet to send out with these switches.
