Geothermo is great if you have it, but it takes a lot of money to install for the few days you need backup heat. A regular gas furnace is a better backup.
If you have geothermo sized right for your house and climate you don’t need a backup at all. However at the expensive of installing it you can get a modern air source heat pump for a lot less $$$, and so overall that is the better plan for most people even though in many climates you will need some other backup heat source for the days that it gets too cold for the air source heat pump.

isn’t geothermo the primary?

Ok I think I see what your saying. All the same I would love geothermal with heat pump but I can’t even afford a stand alone property to begin with.
