Hey everyone, it’s pinned comment time! And there are some corrections and clarifications here. Exciting!
First, heat pumps part 1:
https://youtu.be/7J52mDjZzto
Second, refrigerants! Sloppy script-writing me didn’t catch that I implied CO2 as a refrigerant was the only other option, but it’s not! There have been many climate-friendly refrigerants in use in lots of applications such as isobutane and propane, but the main trouble with these is they go boom sometimes. In larger systems the quantities needed can be dangerous which is why R-1234yf and CO2 as refrigerants are important!
Third, heat pump dryers! My explanation into them is, um, well not right. It’s better to think of them as giant dehumidifiers that recirculate air through the drum. Heat slowly builds up, but it’s not really being taken from the room. Instead it’s just the heat created by the compressor being continually recaptured, and a sort of thermal feedback loop forms. The cold surface of the evaporator also pulls the moisture out to be collected. Here’s a video from This Old House that has a great diagram (though the refrigeration cycle’s magicalness of latent heat is pretty much skipped)

Fourth, I regret saying it's a "myth" that tankless heaters provide instant hot water. More fairly I think it's a misconception.
Fifth, I dunno! I’ll add stuff here as we go along. Aren’t pinned comments neat? I love being able to put information right up at the very top for you so you don’t have to waste your time commenting!

Kk. Im tired of you complaining about greenhouse gases.. did you know that that causes more trees and plants to grow? Did you know that this is exactly what happened to the planet prior to the current ICE AGE that we are currently in? Did you even know that its cyclical that we go from ice age to greenhouse? Like wtf, research more kid

Here in the UK the price of natural gas is going up significantly, which is driving up the price of electricity now we depend on gas to generate it. Heat pumps sounds like a great idea until you see the cost of replacing an existing central heating system. Unfortunately, it's not feasible for most families that don't own a reasonably modern home. The place to start is new builds.

Thank you for a detailed information about geothermal heating!
Our housing cooperative in Finland just finished drilling 42 holes, totalling more than 10 kilometres into the ground to switch from district heating to geothermal heating. We have 138 flats and 9 buildings. We also installed 250 kWp solar panels. At least so far electricity is cheap and fossil fuels very expensive here. Every heating system is required to operate at -29 °C (-20°F) here.

Waste heat from power plant might be better used to warm commercial greenhouses that grow food. They could be located near these power plants. I doubt most people want to have their homes close enough to one of these power plants to benefit—and only for the winter months—from its waste heat.

Regarding the cost of installing a geothermal heating system in your home, I feel like a point worth mentioning is that a lot of that money will go directly into the value of the house.

(re: When you add the alarm/warning graphics) As a Canadian, it's so hard to imagine being this hesitant to criticize the free markets role in creating awful energy-cost incentives.

But I understand, I think we do better to stay out of the arena of politicians.

Fantastic video, btw.

Heat pumps of either kind do not produce heat at a sufficient, or necessary, temperature. Gas based boiler systems produce washing and radiator water at 60degree Centigrade. Heat pumps struggle to get to 40degreees centigrade. This makes space heating inflexible where it can take a day or more to bring a house up to a tolerable temperature. It also means that when a householder wants to quickly increase – or just as importantly, reduce – the temperature in their home, it can't be done. Heat pumps can be effective adjunctive heating but gas boilers will be necessary for a long time to come. And they do already cover all possible contingencies.

First, as to the idea that slamming a reversing valve while the compressor is still running might not be bad for the system, @PracticalEngineering has a couple of videos that explain fluid hammer and why slamming valves with fluid still flowing through them is generally not a good idea. Second, I appreciated the "Pull Up! Pull Up!" easter egg in the Too Deep Alert. Had me laughing so hard that I was afraid that I might wake people up!

What’s the environmental impact on the variable frost line and earth/soil displacement when there are 100 million plus homes and work spaces (just here in the US) utilizing this technology?

As an aside, the current ground installation reminds me of a septic tank drain field, at least in concept, and certainly purposed differently.

I just saw a video clip of VP Harris announcing a partnership with private companies to develop electric heat pumps.

She also might've mumbled something about you being brilliant, I dunno, I'd started to walk out of the room to go get more coffee.

You said something early in the video – "Ideally we'd have some sort of pricing structure where the cost of each energy source is related to its emissions".

How would a system like that work? Prices are based off of supply and demand of a resource – changing that to be related directly to emissions kind of undermines that supply/demand system, and I'm curious how it would work.

In the Twin Cities my gas bill in December, January, and February is around $150 per month, and I keep my house warmer than most people do. In the summer my gas bill is maybe $20.

I get to NOT live like a caveman for well under a grand per year, closer to 6 or 7 hundred.

Until Brandon showed up gas prices were decent and supplies were plentiful.

Your take on this reminds me of people who put 25 grand worth of dopey-ass solar junk on their homes to get out from under a $100/month electric bill.

Gas is cheap and simple and so are furnaces. You can dick around with this nonsense but compressors require a lot of electricity to run, and the lukewarm air coming out of these wastes of money only gets more lukewarm as things get dirty in there- it runs longer and you get less heat.

I don't like running my A/C in the summer because of the cost, so expecting me to like running it in the winter for piss-poor heat (at best) sounds rather absurd. I'll stick with my delightful natural gas thank you.

I don't have the time to read through all the comments to see if anyone else has brought this to your attention yet (I would hope so, but just in case) many if not most water source heat pumps have hookups where they can also heat your homes hot water (I would assume mostly in the summer when the system is in AC mode). This saves even more energy costs as the hot water heater doesn't have to run as much if the water going into is already warm/hot from the heat pump.

Great job on the video's I've been enjoying them.

My town actually does district heating from trash incineration, and the town one over does it from fermentation in a sewage treatment plant. There really is an exciting number of options beyond just yeeting mains voltage across a resistor.
