Furnace vs mini splits

[stoveliker]

Just as an anecdotal data points, I'm running the mini split now in addition to the basement stove (stove does fine at 0 F, but 5 F and 40 mph wind is tough).
This is not a hyperheat.
At 10 F.it was blowing 110 F air quite consistently.
At 5 F it was blowing 109 F air (max; it depends on the cycle towards defrosting, other times it was 100-105).

It raised the temps inside the home easily by 2 degrees. (Despite multiple defrosting cycles).

I think the cop of this one at 7 F is 2.1, so I did likely use quite some kWhs (but I have plenty of those in my solar bank so I don't care).

I have a 12k BTU mini split and an Emporia energy monitor. The power use depends on how hard it's running which depends on the delta between room temp and set temp. When it's really cranking it pulls about 800-900 watts. When it's closer to set point and dialed down it pulls between 200-400 watts.
In heat mode the defrost cycle draws close to 1 kW for 3-4 minutes.

But on the sprinter forum they telling me everyone in NE is freezing because heatpumps don’t work when it’s cold😉

I need to add a mini split or two. The kitchen is the longest run. It’s too warm in the summer. And the basement is to cool in the winter. It’s either a dual head or two singles. I need to they won’t ever run at once so a dual head 12k unit with two 12k heads is what I want. But they don’t like to sell that as a DIY kits.
