Thermostats work - both come on and off normally depending on how I
set them and they properly apply voltage to the heating elements.
Both heating elements show 15 ohms and draw 17+ amps.

Anybody got an idea what the problem could be?

It wasnt like this last winter with the cold winter water temp and
everything else is equal, maybe a dip tube. 2 showers and cold
incomming water is a lot of immediate load on electric, was water temp
output as hot last winter.
