My parents run a wood fired boiler that supplies radiator heat through the house. I.e. it heats the water/antifreeze solution and it's pumped through the house into baseboard radiators. The boiler could easily be converted to propane or some other means of heat source. Best of all, it's in an outbuilding about 50' away from the house. Piping goes underground.

It's kept their house pretty warm through Ky winters over the last 10 years or more. They're getting to the point where they're not able to stoke the fire 2x daily so they're looking into heating/cooling via mini-splits (heat pump) and maybe converting the wood furnace to propane and supplementally heating with that in the winter.

They're living in a 150 year old redone log cabin out in the middle of nowhere.

It depends on how long you're going to stay in the house, but there are lots of options for heating.
