Wow I had no idea, thanks for sharing the source.

I saw it on there among 20+ other chocolate bars.

Maybe need to get induction instead of radiant? Induction is much more efficient.

Really exciting development for the climate change mitigation toolkit. Let’s hope it’s not too challenging or costly to scale up and deploy.

The recovery time, aka first hour rating, should be in the specs for the models to find one that suits your needs. There’s more detailed research on them available as well if you’re so inclined.

You can, but not as a heat pump so you wouldn’t get all the efficiency gains and it will very often end up being more expensive to run than gas tankless in the near term.

Yeah, those are all good points and certainly factor in. There are objective studies about human comfort preferences used for building design. I expect OPs question is a roundabout way to ultimately ask about comfort preferences.

I do 80F during the day and 78F at night in the pacific northwest US. It usually gets cold enough at night that opening windows will cool my house to the low 70s overnight. In the winter I have it set to 68F. I use ceiling fans and appropriate clothing to stay comfortable within those parameters.

They literally need to meet airtightness requirements to meet the Passive House standard. It’s tested with a blower door test to check the air exchange rate at a prescribed negative pressure. You may be referring to a loose definition of passive house, instead of the standard, though. Airtightness is not “awful” as you suggested - mechanical ventilation provides fresh air

I can see why you would think that happens, but it either doesn’t happen, or it does and the shit water gets washed away by the continuous spray of clean water just like taking a shower.

I actually don’t mind it, especially in the summer. You can get heated ones that cost more. Maybe my anus isn’t that temperature sensitive?

How does getting in the shower save time over the 10 seconds it takes to spray your bhole?

A bidet. You can install it yourself in 20 minutes and enjoy a lifetime of cleaner buttholes and save on tp.
