Changed everything on HW heater but still hot water runs out fast...

[homeby5]

Ok...I had a thread going earlier about changing my dip tube. I finally did it and the old one was ok. Installed new DT anyway.Thanks for your help on that one.

Anyway...I have now changed every component on my tank. Both new elements, verified 19 amps across each element when in operation, both new thermostats and a new dip tube. Also drained all the sediment from my tank. But my HW seems to still run out after 10 min or so in shower. It's a 50 gal dual element electric HW tank.
I'm dumbfounded. What else could it be? It's an 8 year old tank.
Thanks guys.

How many gallons per minute does your shower flow ?

What temp do you like your shower ?

What’s your cold water temp ?

What temp is your hot water ?

I live in Key Largo Fl so my ground water temp is usually consistant at around 72.
Not sure about shower gpm but nothing has changed from before.
We have HW set at about 135.
I dunno...shower not steaming?
I do knownthis. Until about 6 months ago I could fill a standard 5ft tub with HW with no problem. Now...I run out with the tub half filled. As I mentioned, I changed everything on the tank and cleaned tank but still, not much HW.
Weird...huh?

Sorry to hear you spent $$ and time on something but didn't get results. Let me ask you this does everything else get hot water or is it just the shower having temperature issues?

FYI 8-10 years is how long these water heaters last nowadays.
A few things to take into consideration. One is water flow into the water heater.
Two is temperature lat the WH and leaving the unit. If those are good then I think you have a clogged/bad cartridge within the shower fixture.

Turn the cold water off to the water heater. Then open a hot water faucet and drain the residual pressure off.

The water should stop. If the water is still flowing then you have a cross between hot and cold some place.

Post a picture of how the thermostats are wired.

Check for a hot water leak.

I checked that. Thanks.

UPDATE:
I found the issue and I apologize for my false alarm with some misinformation.
My new Tstat stopped working. I just checked it two days ago when I changed my dip tube and between then and now it stopped sending 240v to the lower heating element. When i wrote this thread i had just checked it a day before but then it stopped. This is brand new one that is less than a month old. Sooooo...back to Lowes I go to buy another Tstat kit.
Thanks again guys.
