So I just installed an AO Smith signature select 50 gal electric 5500.model E940R55DV110. It has an Apollo MVBLF mixer on it and piped in with PEX. Running 10-2 MC to it on a 30 double. I have turned the thermostats on the unit up to about 130-135 and got “hot” no steam water. I made sure the lower was higher than the upper also. I then opened it up all way on the mixer, counter clockwise, for hot water and took a shower after about an hour. When the water was turned all the way up, all the way, it was what some would call a hot shower. If I turned it down to where it used to burn the hell out of me it was now warm, bordering cold. A couple days ago my 15 year old GE unit went so we had to replace with this one. It had no issue with making water hot enough to skin a cat so we got used to hot water in our house. I waited about an hour after bathing and got a cup, let the water run full hot and temp checked it with 4 different thermometers ( don’t ask why I have that many lol) all read 106 degrees. That is lower, much lower than what the thermostat is set at. This unit was installed at 3pm est and all of this took place up until this morning post. I checked both elements for continuity and beep beep they are good. Can anyone suggest why not hot water isn’t peeling my skin on full bore all of a sudden...and what I can do to fix? It s so frustrating!!!!
