Same here. I save a lot with a variable speed heat pump, supplemented with electric heat strips. It’d be cheaper to supplement with a natural gas furnace if I didn’t have solar and battery storage usually having enough charge to power the heat strips through most of the night.
During the warm half of the year I save more money by directing the cold air output from my hybrid water heater to an intake receiver of my central HVAC. This allows my variable speed heat pump to stay in low speed for more hours of the day.

Yep...they’re pretty efficient and can produce about three times the heat for the same amount of energy that the strips would use within their efficiency range.
For colder weather, we use a propane boiler, low-speed pumps, circulate water thru PEX up under the floor joists (properly installed, insulated, etc.) to create a radiant heat floosr, and we do this in 3 different zones throughout the house.
It can be 20 below outside, the house (6” exterior walls with R23 and R30+ in the ceilings) will stay at a nice 72 degrees with minimum use of fuel. That boiler could easily be changed out to utilize a wood pellet boiler should FJB really go off in total insanity.
