Can anyone explain the recent fascination with heat pumps? I first noticed it with Technology Connections. Here in sunny Western Australia heat pumps have been the norm for a long time. Our climate has historically been dry enough for evaporative air conditioning to work as well, but for some reason (/s) the climate is changing such that this is increasingly not the case. That said IIRC these units have been common in my life for decades, so I assumed that the rest of the world had cottoned on.
- sokoloff 5y agoIn a heating dominated climate, heat pumps have been slower to catch on due to declining efficiency and performance exactly when the heat loss of the building is the highest. (The same effect happens to an extent in heating dominated climates, but it's more rare to have 72 straight hours of outside air temp 20°C hotter than desired inside than it is to have 72 straight hours of outside air temp 20°C colder than desired inside. Even when those conditions exist, having the inside noticeably cooler and drier than outside is still relatively comfortable, while having an inside temp of 15°C is somewhat more uncomfortable.)
