    doing the math, tankless heaters use insane amounts of electricity. we were gonna use one for a detached guest house so we could skip the insulated pipe, but holy shit the cabling we’d have to install

      Depending where you live, the tankless heater might run on gas.

      Which is sometimes better for the environment than the electricity, if the grid is coal powered.

        i don’t think those are approved for installation in buildings here. and i wouldn’t want gas in my house anyway.
