Heat loop at water heater, other ? too

edwardh3 · Mar 10, 2008

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.
