I would like to install a tempering tank to increase the first hour rating on my water heater.
I was thinking about using 2 4" dia PVC piping lengths. If I raise the water temp coming in building from 50 to 70 deg. F, then I just have to heat the water from that point to 125 deg.
My questions are can I use PVC with potable water?
Up to what pressure could i use PVC to?
Does anyone have any experience with this?
Will it work?
