Cooling BTU's

[addicted56]

I know most people that build yurts live in climates that require

heating

. I on the other hand need cooling.

I will be placing a couple ductless mini-split units and I do have the

insulation

kit on my

Colorado yurts

.

I will be running a heat pump water heater in the pantry of the 30' yurt (approx 150 SQFT) and we have a 110V 6K AC unit that is filling an old gap that was cut in the yurt from the last owner that had a evaporitive system. This is mainly there in case we have a power outage I can run the 110V unit on the generator and keep at least one place in the house that is not boiling, though I doubt it will actually cool anything in that space.

So I was thinking an 18K BTU unit would be plenty for the 30' yurt and a 12K unit for the 24' yurt. Thoughts or does anyone have any experience in this department?

The 24K BTU unit is only 80 more bucks but I know systems are not as efficient if they are over or under sized.

Also thinking about running one of the portable heat pump units in the bathroom to keep it dry in there and to have something in the 12K BTU range that runs on 110V in case we have any hurricanes this year and we lose power in peak summer. 100 with 90% humidity is not fun.
