Heating systems for new home

After learning more about how efficient mini splits are I’m reconsidering them for a new house.

The new house is gonna be on a 4 ft crawl space, due to ledge.

I was leaning towards a forced hot air system with a heat pump (heat and cool)

Probably a direct vented propane stove for back up.

Some pro’s and con’s of each:

The forced hot air system:
would cost a lot more. Probably double or more.
Would turn the 4ft crawl space into a 3ft crawl space for duct work.
Would allow integrated humidifier
Would allow integrated air quality control (fresh air intake)
Not sure how close to a mini split efficiency you can get.

Mini Split:
Super efficient
Probably easier to control “zones”
No way to humidify with them.
No way to manage fresh air (that I know of)
Kinda ugly wall units.
Ever so slight fan noise.
Need to get plumbing to each head unit.

You have to be careful with tight energy efficient homes these days with indoor air quality. Need to pimp in sone fresh air. I could put an independent system.

The new house will be a post and beam an I would like to manage humidity some in winter to minimize to much beam checking. And health wise. I’ve not had the best luck with central humidifier systems. Assuming they have better stuff these days. Lots of issues with these. Types that make steam are expensive to run. Cool mist type systems are prone to mold.

I also plan to add Solar. And I think we have ruled out geothermal (which is basically a heat pump).

Any thoughts on this topic.
