Should I buy a Tado system?
I am thinking of getting a smart heating system.
I have a quite a large house and three teenage children.
The children are all coming and going at different times.
My eldest child has a bedroom on the front of the house which has a bay window. The wall is very thin in the bay, and the window consists of 14 double glazed units in aluminium frames. Her room and the "TV room" below it are noticeably colder than the rest of the house.
My other daughter also complains that her room is cold and that the radiator "doesn't work", but of course it does but only when the thermostat in the hall gets cold enough to put the heating on.
I did try to put a second wireless thermostat in the front bedroom (with the bay window) so that if it got really cold in there it would override the one in the hall and put the heating on, but this makes the rest of the house too hot.
The boiler is a modern condensing combi boiler.
Downstairs there are four radiators, on in each room, one in the hallway, a small one in the kitchen and a fan based heat exchanger under a kitchen unit that blows into the dining room.
Upstairs there are three rooms each with a radiator and a towel rail in the bathroom.
In the loft there are two radiators in my office that turned off and two in another bedroom. This bedroom is quite warm as it seems well insulated and we like it quite cool to just sleep in there anyway.
All of the radiators have thermostatic valves with only the towel rail being unregulated (you have to have one unregulated so at to not overload the pump in the boiler).
Ideally I would want to be able to turn on heat in individual rooms, probably the two girls rooms and maybe the downstairs cold TV room. Another option might be that the girls rooms only cause the boiler to come on for their rooms when they are actually in the house. I don't see the point of pouring heat through the bay window upstairs when no one is in the room but equally I don't want my daughter to feel so cold; she seems to suffer mostly at night.
Everyone in the house has an Android phone with a data plan.
I can see how a Tado system might know whether people are in the house or not, but I don't see how it would know what room they are in, maybe that's too much to ask.
I guess if each child can control the temperature of their room (within limits) but only if they are actually in the house then that would be pretty good.
Would Tado work in my scenario and what would I need to buy? or should I get something else?
Installation is not a problem. I am an engineer and installed most of the heating system originally myself anyway.
