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!
600 gallons for 17 dollars? That’s very high to me. We pay about 1€ per 1000L, so 600 gallons would cost about 2,20 euros.
America has a lot of desert and water starved areas, so there are higher costs in parts of the states.
