Technology Connections has a good video on heat pumps. (Actually several of them, I link the newest one.) https://www.youtube.com/watch?v=MFEHFsO-XSI
That channel is fascinating. They have created some incredibly interesting projects.

Re: How a heat pump works
#12What is going on? Is there a global push to get everyone to switch to heat pumps. It seems that there is heat pump content everywhere. Clearly there is a push. I understand that its for climate benefits but it feels very coordinated. edit: didn't realize the attention I would get. Let me add someone answered my question -- a good product market fit and people talking is probably where the push came from. That said HV…
Wait till we have Heat Pumps built with Rust!
But seriously i think it’s just that awareness hit a critical threshold so the hysteresis kicks in and articles proliferate. In both cases.

Heat pumps are the opposite of AC. AC industry is behind this for sure. It is like a paid PR campaign. It is not more economical then gas. So now gas is going to be punished for factors X,Y,Z.
It is coordinated. I wish there is more investigative research into who and why they are doing this.

The reason is that suddenly everybody understood that Russia is an unreliable partner for their countries energy needs (at least in Europe).
For consumers it's also became clear that being slightly more independent from centralized heating and/or energy infrastructure is a good thing

That and gas stoves bad.
The 'gas stoves bad' movement isn't a push, it's a pull.

> Is there a global push to get everyone to switch to heat pumps. I mean, yes. They're much more energy efficient than the alternatives and will play a key part of removing our dependence on fossil fuels. > I understand that its for climate benefits but it feels very coordinated. That seems like a good thing?
They are not more energy efficient than burning gas.
Edit: since i am getting downvoted to oblivion, let me fight back here. I genuinely wished heat pumps would be more efficient and in theory they can be. I would love to not generate heat and just use the outside heat energy and compress it down into a smaller location.
But compressing and decompressing is not an energy efficient task. It takes a lot of work. Mechanical inefficiencies are a huge energy consumption. Gas is simply burning fuel. Yes, we should save gas for rainy days. But I hate to say that it is more efficient and cheap. There is no comparison.

A more plausible explanation is that the we HN-ers are a bunch of nerds and heatpumps are excellent nerd-bait
Re: How a heat pump works
#18The heat pumps are one of the means of heating (and air conditioning) in the heart of the news. What is their principle of operation. You can ask questions here if there are points to clarify in the course
I'd like to get a heat pump to replace my existing baseboard hot-water system (currently powered by an oil furnace) without converting to a heated air system. From what I've read, that's not quite feasible yet, since current systems can't produce a high enough temperature. What are the prospects of that technology becoming viable in the next few years?
It partially depends on your climate. I’m in Portland, Maine, so for us, we have a natural gas furnace with radiators, but they’re heavily supplemented by a few heat pumps. For us, the temperature frequently gets very low in the winter, sub 10°F, and this is the point when heat pumps aren’t as efficient. An ideal set up in a small home could be heat pumps running off solar and a woodstove for when it gets really really cold.

It's a great way to lessen the demand on fossil fuels and the power grid.
Manufacturers are obviously pushing, but many utility companies and municipalities are too. Basically the electric car or solar panels of HVAC. It's one of those things where there are a lot of incentives for everyone involved all the way down the line.
