Dad-gum-it, this thread has been on my mind all day. I have been ciphering on what DAZ wrote in post #9, about the hot water line having a cold water intake.....I think he was referring to the bypass. I posted later that the bypass should be completely closed, as many of us know it should be.
For those people with small children that want to make sure they don't get burned by the extremely hot water that comes out of an RV water heater.......what would be wrong with leaving the bypass cracked open ??
Hear me out, here. Having a little cold water introduced to the hot water line before it gets to our faucets might not be a bad idea. I don't see where there would be any reduction in total time for a hot shower.....you still have 6 gallons of water in the water heater, so being premixed before it hits the shower should not be a problem. Washing dishes and such, you might not even have to mix with cold water.
The problems that I see would might be some water "creep"...hot water backing into the cold water line, but could easily be solved by a check valve in the cold water line before the bypass valve area.
Am I missing something here, or could this work ??
