Wow, I just saw a great place to live..

3011 Teller County Road 1, Cripple Creek, CO 80813 - Zillow

1200 sqft of south facing roof?? The very first thing I would be thinking about is PV panels!
Have you given PV any consideration?

The problem I have with snow and lack of sunny days most of the heating season,
makes me reluctant to say what I've done helps with the heating bill..
Mostly the impact is on the Radon in the basement.

However, this is my first 'spring' with the system in place, and so far I like it.
Since the basement is uninsulated, I'm pleased to see the 49F move up to 52F in a partly sunny afternoon.

Even today, when it was mostly cloudy (but got into the low 50s), we had the blower running a few hours. And, that's with the differential setpoint at 15deg F..

One other thing I noticed today. Since the A7 hotwater heater in the basement was really
pulling the basement air temp down, the warm attic air worked very well,
in counteracting the cold air coming out of the A7 ASHP..
Within an hour after the A7 shut down, the basement temp was recovered.

One of these days, (in May?) it's going to start warming up the basement like crazy.
I hope! And I'll have to add a top limit to basement temp..

Of course, that might be wishful thinking on my part..
