I concur with Bazinga. Yes I recommend the system. If it saves me money as well then that is a bonus. Indeed from current consumption levels it does seem they have gone down. But it more than about saving money. It is about having a better balanced comfort and heat when and where you need it.
I am sure I have said this before but it does seem where one or two have problems, apart from the odd failed device, these problems are peculiar to their installation or indeed possibly incorrect installation.
I recommend it. Plus shorty I may even be able to operate my heating from my watch Honeywell having in the USA updated the app ready for the Apple Watch!
