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.

Fascinating idea. Sounds like it will be nearly improssible to implement at scale and long term in our current world, but maybe some of the ideas could be explored further as options to support laborers and mitigate wealth hoarding. Thanks for sharing.

I agree lawns are dumb but from an environmental perspective they can be net carbon sinks, which I found surprising. Though they are still bad for other environmental reasons.

Some are parasitic, most are saprophytic (decomposers/recyclers), others are symbiotic and exchange nutrients with trees

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.

I can see how it’s strange on the surface, but ultimately the carbon emissions wouldn’t be there if the polluting activity was not funded. So to whom would the carbon emissions be attributed otherwise? Just the CEO?
