  • depending on the outside temperature, there’s a limit to what the heat pump can do, which an internal electric heater inside the water tank takes over to reach usable shower temperature.

    That is also true for solar heaters when there is no sun. and there are not many places that have climates where heat pumps cant operate these days.

    Also air source heat pumps can have a COP of 3.5 so or higher. so even with a lower efficiency from the PV you might get ahead. You also get gains from the high COP on cloudy days where you might need resistance heating on the thermal one

    I dont think you can claim any of them is better without doing the math.






  • does this apply only to the internet? e.g. are you against laws that prevent stores from selling tobacco to minors because it’s their parents responsibility that they don’t smoke?

    Im not saying Texas’ solution is a good idea, but also I feel it is at least weird this contradictory situation between the physical world and the internet







  • Unfortunately most western states have completely ignored for years the atrocities committed against the people in Palestine. Not allowing these kinds of protests also prevents people in those countries from voicing their rejection of their governments position, making it more difficult for those governments to change their postures.

    Putting pressure on Israel’s allies is for most people the only way they have to support Palestinians
