Hmmm - this data center pushes out a lot of heat. I wonder what it could be used for? How about heating homes!

Data Center in Denmark shows how to turn a cooling problem into a heating solution for thousands of households.

Water from the city’s district heating network is run through the data center’s cooling units, where it is warmed. The water then goes to a nearby plant full of heat pumps, which boosts the temperature before the water goes out to heat homes.

Here is the KEY to making this work. The tech involved is simple.

The hard part is having a pipe network already in the ground and being relatively close to the houses to be heated. https://scienceblog.com/m-a-data-center-in-denmark-gives-away-heat-that-data-centers-often-waste-it-runs-water-from-the-citys-heating-network-through-its-cooling-units-and-into-heat-pumps-that-raise-it-enou/ #DataCenters #DataCenter #Cooling #Heating #Electricity #ElectricGrid #HeatPumps #ElectricPower

Why Google is helping homeowners buy heat pumps

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.html

It'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 heat

Cons:
* Uses outdoor space, yard is also small
* More expensive, outdoor unit needs 240v
* Outdoor water lines could freeze

🧵

First, #GE’s #Geospring:
https://cleantechnica.com/2025/07/10/ges-new-heat-pump-water-heater-takes-the-technology-to-new-heights/
https://www.geappliances.com/appliance/GE-Profile-GEOSPRING-Smart-Hybrid-Heat-Pump-Water-Heater-80-gallon-120V-FlexCapacity-PF80S10FPY

This 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 summer

Cons:
* 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.

Naomi Klein:

"That’s why I talk about things like public transport, the price of heating, the price of food, and so on. The less we get into abstract debates about the causes of climate change, the better."

"The left has become very academic and elitist. Its message is out of touch with the people. When you mention carbon trading, people don’t understand what you’re talking about."

@dmoser Interesting PR campaign to discourage #heatpumps in UK. Home heating/cooling costs are borne by residents while UK government enables #gas promoted technologies including #hydrogen. Effect of #Brexit?
