I'll see about half-closing the upstairs registers and monitor temp/humidity downstairs.
I am curious to run some numbers to see cost of heating from an HVAC vs natural gas. My baseline understanding is that resistance heating is 3x more expensive than NG, but heatpumps are 3x more efficient, so about even in cost? I'll look at my utility costs and do the math.

Here's a link to some of the new units. Output wise it looks like one of these will finally work for me. Below like 2.2 cop though its more expensive to run electric for me so i would really want some sort of european wood stove (ultra efficient with variable cfm output as well).

Interestingly i did see that the outdoor pump is variable output, but the blower fan indoors is single speed. I wonder how converting to a variable speed indoor fan would go.
