"Americans bought 21 percent more heat pumps in 2023 than the next-most popular heating appliance, fossil gas furnaces." Quietly, the way we heat our homes is changing - and it has the potential to make a big impact.

Because heat pumps use around a quarter of the energy of a conventional furnace, and don't necessarily depend on fossil fuels at all, the aggregate energy savings could be really significant. Anecdotally (I have a steam furnace that I hate with the fire of a thousand suns), it's also just a far better system.

It might not seem like a particularly sexy technology, but there's scope to spend a little effort here on UX in the same way that Nest did for thermostats and make an even bigger impact. #Climate
