Date: 2024-03-30 01:42 pm (UTC)I can see that putting thermostats on ducted-air vents will be more complicated than radiators, but the answer to over-heated south-facing rooms is not separate heaters in each room.
I do fear that moving away from a building-wide system is a mistake.
If the furnace is in the basement, ground-source heat pumps would be possible, though not cheap, and would use the summer heat in winter.
If the existing heat outlets/radiators are central, I hope they consider how the air-flows will change with the heat coming from the windows.

Date: 2024-03-30 10:52 pm (UTC)Zone heating is increasingly popular for fuel economy, with specialized thermostats and ordinary furnaces. The reasoning being that it's a waste of money/fuel to heat the bedrooms when nobody is using them. Or when everyone is upstairs in the bedroom and upstairs bathroom, you might as well keep the living room cool. What am I missing?

That would still be a building-wide system.
Agreed. It might still be more efficient to generate the heat centrally. Tradition says that economy of scale beats transmission losses, especially when you can use waste heat from some other process.
With a heat pump, which usually has cooler "heat" fluid, it is significantly more efficient to keep a room warm than to reheat it when you want it warm.
Any heating or cooling system works best when the building is well insulated. If you turn the heat off in one room, then heat from the warm rooms around it will migrate to the colder room, so you are effectively heating the same space with fewer radiators or air vents. Or do you have well-insulated internal walls ?
Having said that, since heat pumps have cooler heat fluid, the transmission losses probably mean that they are not great for whole appartment blocks.

Date: 2024-03-31 11:30 am (UTC)It cools, its heats and it doesn't block you view. A condensate pump is par for the course for aesthetic design. Three times the price of an inexpensive window AC unit sounds about right.
They don't mention that you cannot *lock* your sash window with the unit in place, but I suppose that is true with all window AC units.
