Adds no value over the old systems and has twice the problems
This is the worst heating system I've ever used, and I've lived in 4 different countries in very cold climates that require these systems to work properly.
It doesn't do any more then the old battery operated ones do, but it has a lot more problems. I've only been using it for 2 weeks and I've had to contact them 4 times now. Their customer service leaves a lot to be desired as well; with no acknowledgement of my name in the responses and I was even told off for resetting it when, after 2 hours of waiting for a response in winter and not getting one, left me with no choice but to do just that.
We've given up on this now and booked an engineer to come in and change it to something more reliable - who echoed the sentiment btw.
