Questions:
Do you have a heat pump water heater? I'm especially interested in either of these models (Geospring or Voltex X), of course, but they're relatively new and I assume not widely deployed yet. I'm curious to hear anyone's experience with a heat pump water heater, what went well or not. Has anyone seen these split heat pump water heaters (with outdoor compressors) in the wild?
How would you choose between these two models, aside from price? /🧵

Second, A. O. Smith's Voltex X:
https://cleantechnica.com/2026/08/10/a-o-smith-partners-with-panasonic-to-bring-a-co2-split-hpwh-to-market/
https://www.hotwater.com/products/split-system-outdoor-heat-pump-voltex-x/hpaco-45-100/100397647.htmlIt's a split heat pump water heater, with the compressor outdoors. It uses #CO2 #refrigerant and therefore has a GWP of exactly 1.
Pros:
* Can use less indoor space, house is small
* Does not cool house in winter
* No need for resistance heatCons:
* Uses outdoor space, yard is also small
* More expensive, outdoor unit needs 240v
* Outdoor water lines could freeze#HeatPumps #WaterHeaters #AOSmith #VoltexX

First, #GE’s #Geospring:

https://www.geappliances.com/appliance/GE-Profile-GEOSPRING-Smart-Hybrid-Heat-Pump-Water-Heater-80-gallon-120V-FlexCapacity-PF80S10FPYThis is a unitary water heater, using HFO-1234yf #refrigerant, which has a GWP of <1: https://en.wikipedia.org/wiki/2%2C3%2C3%2C3-Tetrafluoropropene
I haven't been able to find a local source, but it seems I can order it online and have it shipped for a plumber to install: https://www.wayfair.com/home-improvement/pdp/ge-profile-geospring-smart-hybrid-heat-pump-water-heater-80-gallon-120v-flexcapacity-ghro1041.html
Pros:
* Can run on 120V, can avoid electrician
* Cools basement in summerCons:
* Cools basement in winter
* Resistance heat backup🧵

Heat pumps, solar and wind could cut EU gas use by a quarter and blunt a next energy shock, a study finds.
Hitting EU targets for heat pumps, solar and wind could slash gas demand by roughly a quarter by 2030 — a saving twice the size of the LNG volumes Qatar could potentially supply to Europe by then, according to new analysis by the think-tank Institute for Energy Economics and Financial Analysis.

Very interesting video from @TechConnectify on #heatpumps and #airconditioning
- Fire based heating systems are often way oversized
- Heatpump = Fridge = Air Conditioning (Same working principle, same device)- Even on very cold days, a few KW of heating is all you need in a reasonable insulated home.
Summary: Heat pumps are highly recommended and often can be of far lower capacity than the existing heating system.

Even in Vermont. “Even in cold weather, electric #heatpumps are more #energyefficient than the gas or oil #furnaces that heat many homes. Heat pumps don’t generate heat. They transfer it. That allows them to achieve more than 300 percent #efficiency in some cases. Because they are more #efficient, using heat pumps to cool and heat homes can help homeowners save money on their #utility bills.” https://www.nytimes.com/interactive/2023/02/22/climate/heat-pumps-extreme-cold.html
