Thanks, that was very helpful.
I found from the chart you posted that A 29,000Btu mini split(with the same components)
would produce 22,420Btu's or 30% less heat (then its rating) on a 23F or -5c day.
It rarely goes below 23F or -5c Where I live, So I could use a unit with about 30% more Capacity then I really need. That should do it.
I could figure out my current use in electricity over the coldest months, convert that to Btu's and size the Mini split accordingly.
And its true rating is for a 43F or 6.1c day @ 29,000Btu's
&
On a warm day 63F or 17.2c it would make 34,000Btu's
Everything points to getting a unit.
