> I installed what is called a "heat pump" in the US for $2500 USD this last summer.

That sounds like a mini-split.

I'm in the US and to me a heat pump involves drilling a bore hole and installing a ground loop.

That costs anywhere from $1,500 to $10,000 depending on soil composition. Then you have the heat pump which ranges from $1,500 up to $10,000. Don't forget your home might have an older furnace, possibly gas or oil that probably needs to be replaced. Along with air handlers and any duct work. And that's only if your home is equipped with a conventional system.

For an older home equipped with radiators or baseboard heaters you're probably better off swapping out your oil or gas for electric but that comes at a cost.

You're thinking of a geothermal heat pump which I do not think is what OP was talking about. Heat pumps are ac/furnace 2 in 1 systems that run on electricity. https://en.wikipedia.org/wiki/Heat_pump

This just isn't accurate though, you're using a definition of heat pump that's personal rather than shared.

Here let me prove it: https://www.carrier.com/residential/en/us/products/heat-pump...

If you're going to insist that air source heat pumps don't exist then yes, heat pumps are very expensive. They do however, and especially in non-Scandinavian Europe, they will work fine.

TBH, that is the definition of heat pump that I grew up with. When people say heat pumps, I immediately think of ground source heat pumps.

Well then, I take it back that it isn't a shared definition in that sense.

But it's a pity, because the air source ones are basically AC units which can also run backward to heat your home, and if more people knew that, they'd install them.
