Take a look at https://www.climatemaster.com/commercial...plications . The systems work just like a normal heat pump/AC system with an outside air heat exchanger, except that it takes/rejects heat from/to a building water loop, which is kept at a more neutral temperature. They're quite common in new buildings, for example 100 Victoria.
There is still a central boiler/chiller to keep the water loop within the temp range, so it's not as totally independent as having units on the balcony.
OK, I see that now. More flexible than a conventional two-pipe system, although the in-unit heat pumps will be more expensive than conventional air handlers. Shoulder-season operation will be less expensive.
So, you are saying that almost all new multi-residential construction in Canada is using water-source heat pumps now?
