Not if you consider the whole "indoor + outdoor" referential, in that case you will always get below 100% efficiency.
- sokoloff 6y agoTrue, but no one cares if they make the outside air 0.05ºC hotter in the summertime or 0.1ºC colder in the wintertime.
- alacombe 6y agoOn an individual level for sure, multiply this by a state / country population, and you get non-negligible impact.
- sokoloff 6y agoDraw a boundary around a city and any lasting temperature change is solely an energy balance question. Any heat that you move into the house in the winter leaks out within the day (asymptotically), so this doesn’t become a localized runaway effect.
