How well does a mini split heat pump work in a LEED or Passive House certified home?
Really well as it happens, see a great example of a split system heat pump installation in the Edelweiss LEED Platinum V4 Home below:
The Edelweiss House has a radiant floor to keep our feet comfortable but we rely on a Mitsubishi Mr. Slim ductless mini-split air source heat pump to heat the air of the house. This gives us air that is heated on average three times more efficiently (and three times cheaper) than had we relied on electric resistance heat in the form of baseboard heaters or our radiant floor boiler.
We also have an air-to-water hybrid electric heat pump hot water heater that borrows that efficiency and significantly cuts the energy required to meet our domestic hot water needs.

I really don't get why a house needs two kinds of heating. If a small bunglaow in Quebec with 8'-high ceilings has in-floor heating, won't its radiant heat warm up the air as well?
Building code requires it.
i want to build a tiny home with 15cm of flooring and air heated inside) with ducts that come from an industrial AC go through the floor and exist top of the walls, this way i can heat/cool the rooms and circulate that air through the floor - all ducts made of special treated pipes for air flow.
I stil did not find why this would not work :) with the exception of the wrong placements of the exiting air, i want it on top of the room but might be best at floor level
in heat mode - air is heated by the heat pump in the AC forced through the floor and exit at the floor level in the rooms
in cool mode the same
although in cooling mode it should exit at the roof level to cool from top down.. that is the issue
