Heat Pump vs Traditional Gas system
 
Is there a time when you dont consider Heat Pump, say like a poorly insulated house?

or does it boil down to something else?

Thanks

Depends on how airtight the home is. You can have a home with no insulation in the walls, but have every crack sealed, and the system will work as good as if the walls were insulated.

The heat pump won't know what kind of house it's in any more than the gas furnace.
Deciding what kind of heating system to use is a choice driven by efficiency, cost to install, comfort during operation, cost to operate and personal preference.
Sizing of a system into a home with poor insulation may eliminate a heat pump system simply because you can't buy one big enough or don't want to put more than one system in.
If it comes down to spending money, in most cases I suggest you spend the money on insulation and tightening up the home first. After you have the home efficient you can put in a system that should never be too big. Being too big for the home makes a system short cycle with costs more to operate, makes the home less comfortable and in most cases will seriously shorten it's useful life.

When we do an oil furnace to hp conversion we do a whole house analysis of the house. Included in our quote (through a partnership with a local insulator) we include bringing up the insulation to current code.
