    I’m not sure that’s true, because coal plants themselves are not very efficient - they’re on average about 30% efficient which isn’t much better than an ICE.

    Take that, transmission losses and the higher resource cost to build an EV, and… It doesn’t look great for them. Sure they can be 90% efficient but that doesn’t matter as much as it should unfortunately.










  • Idk about that unit specifically, but dual-fuel setups do generally have a way to set their switchover points and contractors are basically always very conservative with where they set them… I think largely due to them not wanting callbacks on someone’s house not heating up fast enough.

    You’ll have to research your whole setup and figure out where that is.








  • I recommend doing 3 single head units. Each one can operate at peak efficiency, and they are baseline more efficient too with greater modulation capacity.

    I’m in MN too and have been leaning toward a Gree Sapphire setup or an air-to-water heat pump with a backup boiler. There’s a lot of different kinds though, are you trying to meet your entire house load with the system?
