I believe "mini splits" are also heat pump technology. A year ago I replaced an old propane furnace with traditional "forced hot air" (heat pump technology) both for ac and heat. It works ok, not 100% impressed in real extremes either hot or cold the system seems to run, run, run.. Also mine (most I believe if not all) do not go below 50 degrees in the winter. For 30+ years the cottage has always been kept at 46(ish) all winter without an issue I ever recall. At the end of the day I guess that's not a huge difference, just sayin... We did finally incorporate a wifi thermostat which is great for adjustments on the road so the place is ready (warm/cool) when we arrive.
