    Default Heat loop at water heater, other ? too

    many sites say to put a heat loop on the tank style water water heater to stop the rise of hot water from the heater.
    1. do I need it on both the hot and cold connections?
    2. how high must the loop be (how much of a loop up then back down)

    3. Are there advantages/ disadvantages of flex copper vs stainless steel mesh flex lines other than cost - which is more reliable?

    4. Is there one fitting- not two or 3 that I have to solder together- that will screw into the female IPS hole in the heater top, that the flex connections will then screw onto?

    Thanks.

    The connections to a water heater/storage tank are always thread connections (unless you have a copper tank w/solder conns). The only thing you may need to solder is a male adapter on your cold water supply, and one on the hot water dist. line.
    I reccomend using brass nipples out of the tank holes w/flex connectors to Hot and Cold.

    Good Luck.
