Nothing ironic about that. Using an airco to cool a house is often (not always) a luxury that humans did without for centuries. So people are used to seeing cooling as luxury. Without heating you die.
A heatpump is more energy efficient than most other forms of heating. A heatpump is not always the most efficient way to cool a house.
- ProfessorLayton 1mo agoNotice how you switch from "more energy efficient than most..." when talking about heating, but then switch to "is not always the most efficient..." when talking about cooling. Both are active temperature control, and both are much more efficient than previous forms of heating and cooling. There's also the fact that cooling uses much less energy than heating because the temperature differential is usually much less extreme. It takes less energy to go from 100F/37C > 75F/23C than it does to go from 32F/0C > 65F/18C.
- maybewhenthesun 1mo agoThere are ways to passively cool a house without airco. People have been building cool houses in hot climates for centuries. It doesn't always work, true. Once it is hot 24/7 and you don't have a source of cold anywhere you need airco. But it does explain why people consider airco a luxury item when used for cooling and not when used for heating. I'm not saying people are always right when considering cooling a luxury while considering heating a necessity, but there is a historical reason for that mindset.
- m463 1mo ago> that humans did without for centuries. I think building design/thermal mass and population density/location has changed quite a bit over the centuries.
- maybewhenthesun 29d agoTrue. And it's going to bite us in the ass pretty soon. Already does, actually.
