It is a decent amount of air that needs to be exchanged, but in a passive house, it is done through a heat exchanger to recover some of the heat being exhausted rather than just letting it leak out various openings. On Thu, Jan 20, 2022 at 3:34 PM Jan-GAMs wrote: > The rate at which outdoor air

Not when you talk heat pump. If the outdoors is 60 degrees F and you want 68 degree indoor, you can probably multiply your heating ability by a factor of 10 with a heat pump. Many residential heat pumps can give you 6X the heat energy they consume via electricity. All depends on the

3.41 BTU per watt for resistive heating. Heat pump gives you way more heat per watt. That is why most of the electric cars have gone to heat pumps for the heater. The heat pump Tesla will run the heater for 36 hours and still leave you with enough battery to get home in many cases. Chuck

Mini splits are not manufacturing heat out of the electrical input ( ie resistance heating ) they are moving thermal mass from one side to the other.  So they are making the air outside even colder and the air inside warmer, why the efficiency goes down as it gets colder.  You have to wrap
