When designing a hot water system, specifically one with a hot water loop, what is the max distance for each type of fixture to still be considered instant hot water?
Looking at the EPA water sense guide they tell me no more than 0.5gal of water from source to fixture. They then give us a nifty chart that says how much water is in a foot of x pipe. Great, but that means I can have 50’ of 1/2 pex. I know It takes a long time for hot water to travel 50’ just to wash my hands. Is there a better max length for each type of fixture and pipe size?
