For real. Everytime I get in the shower I end up having to point the showerhead away and cower from the cold water and I could have just turned it on first?

      It’s just dumb engineering to heat up a pipe the entire day for the 0.8% of the day you need it to be hot.

        Insulation + retaining heat means it isn’t nearly as energy inefficient as you think.

        They keep the water tanks heated all day, and not heating the pipes means they have to do more work as they are drained of more water to fill the length of pipe to the shower which will then lose that heat over the course the day, only to need the water heater to heat it back up again.

        Heat pumps generally use a lot less power. Don’t need to heat up much if it is already slightly hot.
