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

It’s totally fine if you have a good seasoning on there. The soap thing is largely a myth. I wash mine with soap every time I use it and it’s still slick as ever

Thank you for sharing the link. Here’s the relevant bit from the article:

Most gas stations don’t want to install new tanks just for E15. Instead, they’re installing blender pumps, which mix the ethanol and gasoline together in the right proportion depending on which one you want. But there’s a problem: if you pump E15 into your car, about a third of a gallon remains in the fueling hose when you’re done. If someone comes along, switches to E10, and buys a single gallon for their lawnmower, they’ll get a third of a gallon of E15 and two-thirds of a gallon of E10. That comes to about 11.7% ethanol, and that might be enough to set your lawnmower on fire.

So the EPA produced a new rule: if you sell E15, you have to require your customers to buy at least four gallons of gas regardless of what blend they’re buying. That’s a big enough purchase that the residual fuel in the hose is too small to matter

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

How is it punishing customers? The rest of the article suggests it may improve things

“It speeds up the process at entry and speeds up the process at the checkout,” he said. “That’s what we believe and we’re going to pilot it.”

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.

Geo heat pump install is indeed very high. But air source heat pumps (both heat pump water heaters and heat pumps for heating/cooling) don’t have that issue and have similar performance, except in extreme climates where geo outperforms.

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.

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