    Default Insulating a PVC hot water line?

    Is it worth it to insulate a PVC hot water line? I am in the process of insulating the copper portions of my hot water lines, but I can not decide if I should do the PVC parts. Obviously the copper parts loose a lot of heat, but I do not think the PVC has anywhere near the same amount of heat loss.

    I don't know what kind of insulation factor PVC pipe has, but I don't think it's high enough. If I were in your position, I'd insulate the pipes. They still experience heat loss, which insulation will help prevent. And heat saved is energy saved is money saved.

    Be sure to insulate cold water pipes, too, if they are in unheated areas (even unheated areas unlikely to freeze -- you never can be sure they won't).

    If you're in a part of the country that gets extended periods of subfreezing weather, it's a good idea to insulate the drain pipes in unheated areas, too, especially any traps where water might sit.
