How would having crossed hot/cold inputs on my electric water heater affect my bill. Has an on/off peak timer.?

by Water Heaters on July 1, 2010

I have been having hot water issues for years and I finally got rid of my old tank. The plumber that is replacing my tank realized that the previous set-up was wrong and the hot & cold pipes were hooked up incorrectly. I am just wondering if anyone would know how this would impact my bill. I had an electric water heater and Im on a time of day (on-peak/off-peak) rate with a timer.

I have no idea how it would impact your bill but if the domestic cold and hot a are reversed you will get more of a tempered water rather than the temp you set the thermostat(s) at . as on the inlet side (cold) of the water heater there is an dip tube the takes the incoming cold water and forces it to the bottom of the tank. and therefore pushes the heated water out of the outlet side ( hot ) and out to the various faucets in your home . If the connections are reversed you will get cold water coming into the tank from the top and than out through the dip tube on the bottom of the tank ,of course unless the dip tube was removed than you would have the water coming into the tank and going across the top of the tank into the outlet side and out to the various faucets give you much less hot water in volume . As for the on off peak timer , i guess it would heat the water just the same as always basically only making hot water in the evening and overnight.

your cold water side has a tempering tube ie it runs to the bottom of your w/h tank,when reversed you are not drawing your h/w from your full tank a short circuit if you will.
