Interesting, effectively each radiator becomes its own thermostat so no longer needs a main one? Doesn't that mean you can only measure temperatures next to the source though?
Yes as you say each radiator valve would in effect become an independent room thermostat. The hub would replace the main programmer.
Whilst nest and hive are interesting to really save money you would want more granular control.
I would also imagine that using such a valve you would be less likely to get stuck pins. Since you could ensure that each valve was opened and closed on a regular basis (eg maybe open and close all radiators once a day in a single cycle of 2 minutes as a preventative measure to stops pins sticking in the body of the valve)
Using something like the above you would be able to create many different zones and control the heating according to your usage of the house. Let’s face it you can only use one room at a time.
E.g you might decide something like the following.
- on weekdays heat the bedrooms and bathroom from 6am-730. Heat the kitchen from 7am-8am. Heating to lounge and dining room off at all the above times.
- in the weekdays in the evening turn on heating to the lounge at 6pm. Start heating the kids bedrooms and bathroom at 7pm. Heat your bedroom from 9pm
- at the weekend during the day turn off all upstairs radiators but enable heating to kitchen and lounge. heat kitchen from 11:45 - 1pm and again from 5-6
Etc...
