  1. Second, A. O. Smith's Voltex X:
    cleantechnica.com/2026/08/10/a
    hotwater.com/products/split-sy

    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

  2. Researchers at our university are developing reversible #heatpumps that provide both heating and cooling year-round using deep #geothermalenergy. This innovation improves #energyefficiency and contributes to sustainable #energysolutions: go.tum.de/988537

  3. Worth a read of the whole article.

    “If Canada is going to meet its #ClimateTargets, virtually everything will need to be #electrified. Gas guzzlers swapped for #ElectricVehicles and #PublicTransportation; #HeatPumps put in place of gas furnaces; and renewable energy moving to centre stage as coal, oil and gas power plants are phased out.” bird.makeup/users/jvipondmd/st

  4. @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?

  5. Did you know that #CO2 can be used as a #refrigerant gas in #heatPumps? And that it's very efficient at it.
    It requires significantly higher pressures than typical refrigerants gas but it doesn't require a chemical plan to fiddle with fluorinated products, and that seems to be a huge plus. Also, it is cheap, guaranteed not to have any undesirable effect we might discover later, non-flammable, non-toxic and has a GWP of 1.

    With a COP above 3, the global #efficiency of a combined-cycle methane power plant + transmission loss + point of use COP gives a higher efficiency than burning the methane directly even in the best furnace money can buy.
    And we know very well how to store hot water, so spreading daily peak heat demand without massive *electricity* storage is much more feasible.
