On the one hand, I'm geekily interested in how tech can monitor and improve these devices.
But on the other hand the info here (e.g. 1% are undersized and 10% are oversized) seems to demonstrate that just rolling out more heat pumps is the important thing and everything else is fiddling around the edges.
Ways to improve financing and the install process and customer journey are the real low hanging fruit.
The idea that construction has low hanging fruit is premised on a belief that 10,000ish years of human construction experience has failed to produce efficiency.
Or, when it comes to installing heat pumps a LLM is unlikely to crawl around a hot fiberglass filled attic cutting holes for air ducts or installing hangers for a mini-split.
To a first approximation, each and every heat pump installation requires a bespoke solution starting at the beginning of the sales funnel and ending with building department sign off. It's local and site specific.
The attraction of construction is the just-one-percent-of-all-Chinese fallacy.
The construction market is mature, liquid, and efficient. It just isn't as cheap as ninety-nine cent apps. Most people can't afford construction. They can't afford sports cars either [I didn't make the economic system and am not saying it is good, just that it is as it is].
