    It being summer here, I’ve stripped the inside walls and insulation. It was built in the 60s and had terrible insulation. I did have to wear a respirator because that era of gyproc used asbestos and mine tested positive. But now I’m furring out the walls on the inside with 2X material to get an R20-24, and I’ll probably add a reflective layer for added heat retention/reflection. I also have to re-do the siding, so I might add a 2" closed-cell layer under that for another R8. I’d like to have it competely passive, with a greenhouse on one side to gather winter heat and circulate. Winter here is pretty much 8 months so I have an uphill battle there.

    I have woodstoves as well, but I’ll run the furnace fan to distribute the heat, so there’s a bit of use, and it’ll kick propane in if the fire burns down, or the heat pump if it’s above -15 outside and I have capacity. I tend to be around 10KW of usage but 23KW of panels struggles some days. After about 5 days of poor sun I’ll be out of reserve, and I fire up the genny for 5 hours to top them back up.

    I’ve considered building a woodgas source for the genny, that would take me pretty much completely off the teat. I’d love to get a groundsource heat pump but those are mucho dinero.

    I’ve also considered melting urea for a cooling source, since we farm and need N for the sprayer. It’s amazing how much heat the endothermic reaction takes, and using a sprayer for topdressing is much more precise than spreading dry fert.
