You’re getting the hang of it!

I’d expect more humid though, which helps with heat pumps. Keep in mind that there are cold climate models that are necessary if you want to heat in a true winter climate, and that the technology has advanced significantly in the last 5-10 years. We’re running 2019 Mitsubishi HyperHeat units, fwiw

I'm in Vermont and it's pretty darn cool here. -7F when I woke up this morning

We have a Rheem HPHW. For outages we have battery backup but in winter it wouldn’t last us more than a day so the real backup plan is the wood stove, same backup plan we had had with our natural gas furnace. That said, the longest outage in the last four years has been 6 minutes

Sorry to hear that. We’re on our sixth winter with them and quite happy with the results

They’ve performed quite well for us:

Air source, Mitsubishi HyperHeat (MSZ/MUZ) mini splits specifically

Efficiency, and therefore range. In the winter I basically always pre-heat, especially on the cold days. Good question about determining the breakeven point; not sure, probably less so for really short drives

According to the data sheet from the manufacturer, it's 2.24 at 5F. Mitsubishi HyperHeat units, MSZ/MUZ specifically

I'm just getting back into doing some home automation / IoT after a few years off and I'm pretty excited by Home Assistant and ESPHome. Sure beats hand coding all of these projects like I've had to do in the past

One thing I appreciate about our Model 3 is that it will warm the battery without being plugged in. This does consume charge, obviously, but from what I've seen it's a net win. Our Rivian only warms the battery if you pre-heat it while it's plugged in. Not sure how other EVs handle pre-warming

Agreed, there is much work to be done to ensure equitable access to at-home charging. That said, with the majority of EV owners being able to charge at home (at least based on reports I’ve seen), pre-conditioning does make a pretty big difference
