  • And what is the problem with a gas hybrid heat pump? It’s an ideal solution for places that get very cold, use the gas furnace for the weeks when it’s below -5 and use the heat pump for many months around that. It’s one of the most efficient ways to use a heat pump as you don’t have to bully it through the coldest part of winter with very bad COPs, you’re only using it when it’s most efficient. And when your heating period is very long, that will only benefit your seasonal COP. So of course it’s more expensive than a simple furnace, but it will also save loads of energy and redeem itself after 5-10 years.

    The best part about this is you already have an AC, aka a heat pump, but you don’t use it for heating?


  • Lightning doesn’t have near the capabilities of USB C. … pretty clear that USB C is superior.

    Are you talking about the capabilities of the USB protocol 3.x, or the mechanical design like I was? I don’t know a single property where the mechanical design of USB is superior to Lightning, but I’m ready to be enlightened.




  • People think that’s a killer argument against heat pumps when it absolutely isn’t.

    In that sort of climate you get a hybrid system or just leave your old furnace in as backup. You’ll use the furnace for the couple of days/weeks when it is below -25c/-13f and use the heat pump for the 6 months around that time window and save huge amounts of energy because you only use the heat pump when it’s most efficient. A hybrid system will improve efficiency because it combines the technologies at transition temps while just keeping the old furnace as backup is obviously much cheaper, since you can also get a smaller unit than you normally would because you don’t have to worry about the coldest period.

    The number of registered cars has risen considerably, even in the last 10 years or so, and cars are getting increasingly bigger. IIRC registered cars in Berlin for instance has risen from 1.2 to 1.4 m in the last decade or so without the city expanding or gaining any meaningful parking space. Law enforcement is typically fundamentally carbrained, so they are lenient on such violations, thinking you can’t punish the poor people who have to park their car somewhere. With modern technologies it could be battled quite effectively, but it’s simply not politically desired in the Autoland. Instead, privacy and bureaucratic overload are made up as excuses on how it’s impossible to get a hold of it.

    I think it goes past mildly on the concern scale. Car centricity in German cities already starkly reduces the quality of life there, and we still haven’t even collectively recognised it as a problem, instead it is still getting worse in 2023.
