check your water pressure and then make sure it is not to high or all the problems you have had were not the answer. it is a pressure /temperature valve not just . temp.

If you have overheating, the elements are working fine and are not suspect.
Also electric power and circuit breaker are eliminated.
ECO reset is not tripped, so that points to faulty TP vlave, but water temperature has to reach 180 degrees F for ECO to trip.
Open link to see ECO located on upper thermostat.

Remaining suspects are 1) bad thermostat or 2) faulty TP valve or 3) Stacking or 4) combination of the 3.
Raise TP lever and gently let back down and see if something was lodged in the valve.

1) If you are certain that water feels hotter than normal, then replace both thermostats:

2) If water seems normal temperature, then replace TP valve:

3) If TP releases water after frequent water use, then Stacking could be part of problem:

Which type of tankless water heater do you have? The Rheem Professional Prestige gas tankless water heater gives error 11 if the gas valve isn't fully open. See the manual here: https://s3.amazonaws.com/WebPartners/ProductDocuments/C5D97959-73D7-4482-9242-83DCE78310C8.pdf . For this water heaters, the first option to check that the gas valve is fully open. If the valve is fully open at the water heater, you may need a technician to check the regulator for your gas line. Every once in a while, I have to contact the gas technician from my local propane dealer to adjust or replace the regulator. It's time to call when the gas appliances have ignition problems due to dirt in the regulator.

On another model, https://s3.amazonaws.com/WebPartners/ProductDocuments/7E641D99-EAB1-49E9-8F8A-53AA99F8E0BE.pdf, the error 11 indicates that the unit could not ignite after 10 tries. This can result from low gas pressure (the regulator issue I noted above), a problem with the igniter (power or oxidation on the spark igniter), an issue with the gas valve wire, an issue with the flame detection sensor or the main control.

I hope this helps. Note: I've found a number of appliance repair technicians who don't handle gas line problems.

Rheem fault code 11 - No ignition. Check to make sure there is gas to the unit and that the pressure is correct. Ensure the ignitor is operational before calling for service. Rheem fault code 16 - This is an over temperature warning which could indicate a possible clogged heat exchanger.

It is unlikely to be the hot water heater causing the smell, it is more likely the input (the well water) having excess sulfur, bacteria and/or organic material

Because it sits in the tank longer, the smell accumulates. If it is a bacterial source, the hot water tank may be a breeding ground for anerobic bacteria. Draining and doing a disinfect with Hydrogen Peroxide (H2O2) is the easiest and safest step

i don't know. be very careful when working with propane.
if this happened to my freezer, i'd guess it was the thermostat. if safe and accessable, consider turning off
fuel supply. if adjustable, mark where thermost's setting is.
turn thermostat down and up or hot and cold a few times.
set the thrmostat at a few degrees lower than the mark.. restart the heater and see if tank will now provide constant hot water.

any plumbing or maybe even an a/c supply should or can get it. there cheap

The 30 Amp breaker should be okay for the 5500W water heater. The Rheem Performance Plus 50 gallon water heater, XE50M09EL55U1, requires a 30A breaker for 208V and 240V electrical systems (single or 3 phase wiring). See pages 8-9 of the manual: https://images.homedepot-static.com/catalog/pdfimages/e2/e20f6bed-6a61-43a8-b7d9-d9dd2dae94e1.pdf .

You should check the installation manual for your new water heater, just in case. I hope this helps.
