Trump's team backing down in front of Harvard should embolden EVERYONE to stand up to them. Do not comply in advance. Instead say "Fuck you, make me."

Most ground source heat pumps (GSHP) use simple 1-stage or 2-stage compressors and typical 24V thermostats/controls. Any of these could participate through a “smart” thermostat VPP…no need for it to be a specific VPP for GSHP

What’s a “sedan”?😉

Hatchbacks 4EVr

Also, no…none are sedans

FWIW, GM has 5 or 6 cars that can do V2H, including the relatively low-priced Equinox…and likely, later this year, the still-lower-priced Bolt re-vamp.

A whistleblower's disclosure details how DOGE may have taken sensitive labor data A whistleblower tells Congress and NPR that DOGE may have taken sensitive labor data and hid its tracks. "None of that ... information should ever leave the agency," said a former NLRB official.

It certainly looks like Elon Musk’s henchmen stole all the data from the agency which protects workers rights, tried to cover it up, and then threatened to kill the guy who blew the whistle on it.

Trump to Bukele: "Home-growns are next. The home-growns. You gotta build about five more places. It's not big enough."

Some personal news: the Department of Homeland Security has given me, an immigration lawyer born in Newton, Massachusetts, seven days to leave the U.S. Does anyone know if you can get Italian citizenship through great-grandparents?

I say this as a pretty rare American who can sew: we don't have the skillset and among those who do the labor costs are beyond what countries like China and Vietnam can charge.

Yeah…that Energy Star page is confusing…but that’s what we get when whoever wrote the tax credit language in 2022 very intentionally assigned responsibility for the efficiency level required for the tax credit to a non-gov’t org (CEE), rather than just refer to Energy Star

Side note: Energy Star is *not* a requirement for the tax credit

Energy Efficient Home Improvement Credit | Internal Revenue Service If you make home improvements for energy efficiency, you may qualify for an annual tax credit up to $3,200.

I don't think she can get the tax credit, since it's a rental. Perhaps it's a grey area if she also lives in the building.

See the "Who Qualifies" section here: www.irs.gov/credits-dedu...

This is going to get worse, not better. Never underestimate the American public’s thirst for performative cruelty towards The Other: defendants, foreigners, anyone they’ve been conditioned to see as less than human. We’re the country that made lynchings into picnics.

Caveat: this would only apply to heat pumps with variable speed compressors. Generally, almost all ductless heat pump systems have variable speed compressors...but the vast majority of heat pumps installed in the US are ducted, and are single speed with no ability to modulate output/efficiency.

36,000Btu/hr for how many hours is the question...

The controls will likely allow DHW to take priority over cooling. With a buffer tank for chilled water, and a reasonably high capacity thermal storage for DHW, it could be pretty seamless for many households. Smart controls would make it even better.

Thermodynamics doesn't really see eye to eye with "where there's a will there's a way"!

15,000Btu/hr is 15,000Btu/hr...though I'm sure Harvest boosts that temporarily with thermal storage

100%

Clean Technica and PV Mag Int’l reprint press release content all the time without investigation. They are not good benchmarks of quality.

Al up to no good again...

Al covering all the bases...

What make/model # do you have? There might be a setting that could be adjusted…

The vast majority of heat pumps will turn on automatically in their previous mode/setting after power outage. Your minisplit is an outlier.

Home furnaces require electricity

For ducted central AC (as well as central heat pumps), the federal rules already changed for units with a Jan. 1 2023 manufacture date or later. Can't roll that back.

I think DOE is supposed to revisit the rules every 6 years

Daikin is already switched over 100% to R-32 at their Houston-area factory as far as I know...they're something like 20-30% of the US market, I think.

Are there announcements on intended efficiency rollbacks? I hadn't heard of anything yet...

Not legit

Got our ground source heat pumps up and running yesterday. Operating at a paltry ~650% efficiency! PS we had two installed (and are 3-phase).

Try Solar...but don't try me
