It takes a few minutes for my tankless water heater to warm up, so we end up wasting a lot of water in our shower. Is there a way to avoid this? A friend mentioned a “comfort valve” or something? What is it and how does it work? Or is there another solution? Thx!

    turn on the shower before you use the toilet

    It’s not actually about the toilet, it’s about turning on the shower earlier.
