Honeywell evohome:
http://www.evohome.info/
The base unit isn't outrageous but the eTRVs are costly. £200 question: can we do the following?
Fit the base unit in the open plan kitchen/living room/diner then use the base unit to control that zone.
Fit standard TRVs in the two bathrooms.
Fit the honeywell eTRVs in the bedrooms such that each is their own zone.
Will a "call for heat" from the eTRV zones override the base unit's control over that always-on main zone?
Could we then fit standard TRVs to the main zone, set to say 21C, such that even if the eTRV zone did all for heat it isn't going to cook the main zone. (but if it drops below 21C the base unit can still call for heat for that main zone)
It's the difference between 4 eTRV heads and 8 eTRV heads. I guess if devious we could put lockshield valves only on all those downstairs radiators then pipe them through a single TRV with electronic head on it for 5, but that's a little kludge like.
