(she/her) @susankayequinn@wandering.shopAre you solar-curious? With the #climate heating & Republicans driving us right off the cliff, you won't regret starting *now* to get more energy resilient.
How to get started:

@Sektorenkoppler@norden.social
Nach 64 Jahren ist unser Haus jetzt #FossilFrei 
Ein wirklich tolles Gefühl.
Ich kann jetzt in Eigenleistung die alte Gas Heizung gefahrlos demontieren
Gute Nachrichten: Laut den Monteuren von den Stadtwerken bauen sie aktuell nur noch Zähler aus.
Neue Gas Anschlüsse wurden schon länger nicht mehr hergestellt. 
@enobacon@urbanists.socialOur car user did not plan her excessive driving and range anxiety appropriately today, so I'm stealing the heater circuit from above the garage to get 240V 12A level 2 going overnight. Thanks to the $500 window #heatPump, (which is on a separate 120V circuit) now the baseboard resistance heater is only needed on the coldest days and nights below 40F.
@frubizym@nrw.socialWas ein Tag 
25kWh Anfang Februar.
Und nur 3 davon eingespeist, dank Wärmepumpe mit großem Trennspeicher.
@OpenSoul@mastodon.socialInvece su Wikipedia vedo che esiste la pagina su l'austriaco #PeterVonRittinger che ha anche lui innovato e creato tra le prime macchine a #pompadicalore (anche prima di Sumner) ma per uno uso di produzione industriale del sale, quindi per uso molto diverso che non per creare un generatore di calore per uso residenziale
DIY air-water heatpump.
No explanations, so let me: He took the exterior unit of an air-to-air heatpump (aircon) and hooked the refrigerant lines that normally go to the interior unit to a small heat exchanger.
There's a circulation pump in the bin cycling the water through that heat exchanger, warming it up. Fast.
It's pretty efficient (calculation in the description).
Given the idiotic prices of commerical air-water heatpumps, this is great!
New clean tech
"A team of researchers from the U. S. Department of Energy #Ames National Laboratory developed a #magnetocaloric #heatpump that matches current vapor-compression heat pumps for weight, cost, and performance."

Want government money for a heat pump? Time might be running out
"So what money is available right now for a prospective #HeatPump buyer? And how might a second Trump administration and a Republican-controlled Congress impact this money?
Here are the answers to your heat pump and money questions."

Outlook for adoption of #heatpump in US buildings: better than you'd think.
States are important -
Heat pumps slash fossil fuel use, and states in Northeast and West Coast have them as key to #climateaction
Together, those states are a big % of US population, so progress can still happen.
Also, market forces seem to be driving replacing electric heat/AC with heat pumps in South, despite little state action.
My neighbors installed a heat pump over the summer (yay, saving energy!) and the thing runs all night long (boo, I may kill someone if this constant hum doesn't stop!).
Anyone have any ideas for sound insulation for low frequency noises? The heat pump is about 10' from my bedroom, my 1958 house has crappy insulation and a raised foundation.
Should I just accept it and move into the living room until summer?
10°F/ -12°C
Feels like -7°F/-21°C
Aux heat (natural gas) overnight: 0 kWh
Heat pump: 100% contribution, only 2kWh used.
I wish i could give everyone a heat pump.
Basically,if we had a serious political party that wanted to tackle climate, and #COVID19, and equity, & workplace safety, & yet be profitable by reducing workers hours lost to illness,
At least one of the two major parties would have proposed a heat pump to anyone who needs one as a Engineering New Deal initiative that would stimulate the economy and return on its investment.
Instead, one political party ignores / denies, and the other suggests building another 3 million homes so Blackstone can buy them up to jack housing prices up.
Last year at this time I was consuming up to 38 kWh on a cold night to warm my home.
Installed heat pump, been significantly colder this year at the same time as last year:
Household consumption around 16 kWh.
or around 5 kWh more than an average unheated, uncooled day of temperatures around 50-68F in September. Easily offset by solar if the sun is out.
Rough estimates of course, and today the wind chill temperature will get down to -9F but we'll see how it goes.
@HunterAnton @quixoticgeek @Sustainable2050
I think, we're talking about winter cold outbreaks when the Arctic jetstream laps South. Such a cold outbreak lasts a week or even longer nowadays. It's a normal occurrence, happens when the polar vortex experiences a sudden stratospheric warming and breaks down.
Every 2 or 3 years, sometimes more than once in a single winter.
And with AMOC slowing down, even longer and more frequent really cold periods must be planned for.
So winter = less solar energy to charge batteries. And lasting extreme cold = home or car batteries can't cover it. The non-adapted power grid can't cope. People freeze to death – like 2 winters ago in Texas.
But I think, with the population density being so high in Europe, and in the Netherlands in particular, district heating should also be considered – and preferred over prolonging burning gas for heating homes.
All gas infrastructure leaks methane. All burning of gas emits CO2.
District heating doesn't have to rely on solar energy but can harness the wind.
#SSW #AMOC #Europe #Heatpump
#today I submitted my #LOCO2024 lightning talk slides, and worked on a #FOSDEM paper proposal (re funding open source)... I am still ploughing through #NewScientist articles, and really looking forward to storm #Bert to warm us up a bit tomorrow (it's about 12C inside) before our shiny new #heatpump goes in next week...
Somehow this year the reversible AC doesn't seem to be able to compete with 16C (weather app)/12C (private weather station nearby) outside. Any hints? I checked the filters and they're still clean from last year.
Also: WTF manufacturers don't leave their manuals online? It can't be that expensive...
(she/her) @susankayequinn@wandering.shopReminder: Trump has promised to roll back any climate gains and that means IRA and tax credits for green energy. So if you were thinking about getting solar, heat pumps, batteries, EVs, or any of the other things that IRA has been giving tax credits for, now is the time. Get it before it's gone.
Note: It's possible Trump will be unable to roll those back (they are very popular) but I wouldn't count on it.
Latest follow-up podcast is out! YouTube: https://youtu.be/Sg2tUn6v1tI Audio version: https://share.transistor.fm/s/5d2f397c Matt had an opportunity to talk to Tom Sahagian about retrofitting apartment buildings in NYC over to heat pumps and why they landed on the model of heat pump they did.
Looking for some #positivity to end the week? I have recapped 46 notable #positive #environmental and #ClimateChange articles from past month including beer brewed with a #HeatPump , the largest county in #Oregon who sued the biggest gas company for making people doubt climate change and #Plastic free #Glitter that is safe for the environment and more.

And after installation our HeatFleet takes over, and uses the device API to unlock even more benefits for our customers, such as
- monitor #heatpump status
- optimized configuration and parameters
And in the future, as we keep decarbonizing homes, we can combine multiple heat pumps into larger groups and help to stabilize the electric grid by slightly changing when the heat pumps start heating (you might not notice the 30 minute difference, but the grid will!)
