    While I agree that our windows are generally superior from a functional perspective, the Americans have us beat in the fact that you can’t install a window AC unit in our windows.

    Hence we get to just die in the increasingly common heat waves. Not great - we’ve got to figure this one out.

    Before portable ACs are mentioned - I’ll point out that they have terrible efficiency, and connecting the tube to blow out the hot air is still terrible with European windows.

      Mini split heat pumps.

      All you need is a 3cm hole in the wall to run a refrigerant line from the outside heat pump unit to the wall unit.

      Window AC units are pretty poor efficiency too, IIRC

        This is likely going to be the answer, yeah, but I believe we need to see some improvements in installability for the average person - a window AC unit does afaik not require a specialist to install, while a mini split, while possible to tackle for a handy person, is a lot harder, leaving the average person to have to pay for someone to install the unit.

        Window ACs are not the best from an efficiency perspective, but they do beat portable units by a large margin.

        EDIT: looks like it might actually not even be legal in the EU to install a mini split yourself - you need to be certified to handle the refrigerants.

        Installation is also more than 50% of the total cost of acquisition, so we’re hitting upon an affordability issue here as well.

          I’ve just been looking into this in the UK (so Europe, but not EU).

          You can now get split units that come pre-filled with a safer refrigerants that a DIYer is allowed to do themselves.

          I would still get an electrician to do the electrical side though. 1KW constant load should definitely be on its own circuit.

          Yeah that’s a good point about affordability. I guess I’d hope for government subsidies or at least supply & demand market forces to address that before it becomes an essential thing, especially if they replace gas boilers too as a move to reduce carbon emissions.

            In the world of theoretical wild policies, there’s a really good argument for subsidizing heat pump installation for places heating with fossil fuels or direct electricity at more than 100% of the cost of installation. I’d love to see that kind of project. One can mostly just dream, though.

        The quoted prices I saw for installation were a lot higher, more like 700 euro, but that probably depends on the cost of labour where you are.

        There are also non-monetary aspects to this issue - I’m not allowed to make any modifications to my facade on account of it being made out of asbestos, for example. I’d have to get a specialist to cut the hole to make that work. It’s also a bit tricky to fit in an outside unit - or inside unit for that matter - on my walls.

        I’m in complete agreement that mini splits are superior, but the downsides do exist and need to be acknowledged.

            Absolutely. I’m speaking mostly from a Swedish apartment-perspective, where ACs have been optional basically forever, but the climate crisis is quickly making them more and more mandatory each year.
