Al up to no good again...

Al covering all the bases...

So much “low hanging fruit” still to pick from the demand response “tree”:

This evening, Dominion called an EV charging DR event, but just for 1 hour. Program rules say event can be up to 4hrs. Result: after end of event, Dom is paying close to $1/kWh (until prices go ⬇️) while my car charges 🤦‍♂️

Dominion Energy (via the PJM Now app) is projecting an all-time winter peak* for tomorrow morning of 22.8MW

Our all-electric house and attached apartment will contribute ~2kW to this load during that hour w/o any special controls or battery system

Ecobee still giving bad advice on the outdoor temperature at which you should shut off your heat pump.

Hint for Ecobee: especially at thermostat setup, the thermostat knows nothing about the house and nothing about the heat pump…therefore it should give zero advice on this topic.

These are from the US...but installed at a 3-story building of flats (apartments)

Heads up: Someone / thing is impersonating @jessedjenkins.com I reported and blocked them.

Heat Pump Mythbuster (#1 of ?)

Myth: New England electricity prices are too high for heat pumps to be competitive on operating cost!

Reality: ~60% of NE households (~3.5 million) use heating oil, propane or electricity (mostly electric resistance heat…not heat pumps) for primary heating fuel.

This is an approximation of our stress level waking up to a 3rd very cold* morning in a row with 100’s of heat pumps installed at our clients’ homes.

*~20F is very cold for us here in central Virginia…wake me up if it gets close to 0F.

New “Heat Pump Hero” t-shirts coming soon for our staff…

Newsflash: the song is actually about heat pumps! Check out the quick glimpse of a heat pump on the brick wall in the video!

Nope.

Now that our kids are 16 and 12, it’s time to finally get rid of the homemade toy kitchen with induction cooktop.

Thanksgiving = peak water heating day in our household. ~18hrs continuous runtime on our heat pump water heater, yet never w/o hot water due to the large tank size (“80” gallon).

Also, remarkably consistent w/ 2022 energy use for the day:

2023: 6.20 kWh
2022: 6.14 kWh

Unauthorized and unofficial Daikin Fit heat pump testing lab is now operational at our office/warehouse in Charlottesville, VA.

What would you like to know about these variable capacity heat pump systems?

Nice to see Daikin has "onshored" assembly of its "Fit" variable speed heat pump outdoor units to the US (air handlers were already made here).

Presumably, the recently launched identical / nearly-identical models under the Amana + Goodman badges will also be made here.

I didn’t do it.
