#3Interesting but federal tax credits for heat pump water heaters is ending next month [1]. It looks nice though.
For people wondering what's up with the "150 gal virtual" capacity, it's actually a 47 gal water heater but it heats water to a really high temperature (if needed) and mixes it with a thermostatic valve to output the desired temperature. For example if cold water was 15 degrees C and you want the hot water to be 40 degrees C, it can triple its "capacity" by heating it up to 90 degrees C and then mixing one part hot water with 2 parts cold water to give you three times as much hot water. Of course, this comes with a grave penalty to efficiency so you should only do it for "party mode".

#4Pretty cool. Reminds me of Impulse. I think there's a big market for home appliances that have more care and attention to detail than we're accustomed to. No one I know is overly satisfied with their water heater.

#5The pricing page does not make it clear how much the actual unit costs, just $6500 with installation. Never purchased a water heater, but going to Home Depot, I see traditional options priced $500-$2000.
Which says you are putting up a high upfront cost, hoping to recoup on increased efficiency. Which could be worthwhile, but you would have to run some simulations if the price is worthwhile. Seems potentially easier to get a dumb water heater to run extra hot using off-peak electricity.

#6A heat pump water heater seems like a no brainer way to improve efficiency.
They're not yet common, but there are many more options available over seas than in America.
This project seems emblematic of the challenges facing funding manufacturing initiatives in America. What's funded are the projects that appeal to tech investors, more of a focus on flashy presentation, luxury design, AI, and cloud app features, than the baseline functionality.
We get innovation as a side effect of convincing investors that the idea will disrupt industries and create app ecosystems that lock in consumer attention. Chasing the 100x unicorns and no longer training workhorses

Yeah this sounds disingenuous. I can also see my heater to 70C if I want, that does not increase its size...

#8The heat pump will pull heat from inside the house? This sounds terrible for efficiency in winter, as you will need to reheat the room

Big problem in the US is that in many regions natural gas is cheaper than electricity, causing heat pump water heaters to be more expensive for the consumer. So everyone ends up burning more.

It is a scalding hazard though. At 70°C skin burns occur in about a second or so.
The thermostatic valve makes it so that the water that comes out of the water heater is at a more reasonable temperature.
