> I'm not sure how you can say that without knowing the heat loss for every room. I can say it because houses are fairly typical and if the heat loss for a room is greater than the minimum head size for a minisplit, the room probably needs some work before you should be putting a minisplit in it. This is all just math, and 6,000 Btu/h (the minimum head size) happens to actually be a lot of heating for any normal room.
