Its not always piped in/outside. IIRC mine the refrigerant never leaves the outside unit, instead hot water (and a shitload of glycol) is pumped around between the unit and the inside of the house. My heat pump only does heating in this configuration though but because of that I got £7.5k from the UK government towards the install, more than half the total cost and that included getting all new pipework and radiators. I assume the idea is they don’t want to be giving people AC as that is seen more as a luxury.
Well it also provides my hot water for the shower, I had a completely new hot water radiator system installed with the heat pump but they are by far the most common form of system in the UK anyway. Convenient to be able to hang clothes on them to dry and the cat loves sleeping on top of it when its on as its warm.

I suppose that makes sense if you’re retrofitting a heat pump onto an existing hot-water radiator system. The unit replaces the existing boiler.
