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!

Idk the specifics, but probably. I've watched many videos on rainwater harvesting and they have storage tanks and pressure tanks.
