Review on 🌡️ Atwood 93105: The Ultimate Adjustable Electronic Thermostat for Optimal Temperature Control by Jon Thompson

Our new Dometic water heater (formerly Atwood but Dometic bought them) often got hot enough to blow the pressure relief valve. Not too much blood; and almost every time we only used it in electric mode. So I reset the headroom (everything was fine) but no luck. I changed the pressure valve. but still it boiled over. So I bought and installed this adjustable thermostat and good luck! I finally found a setting that didn't allow the heater to slam the safety valve - A/B. This variable thermostat should be a standard issue as I believe this common boiling issue is due to stock pressure valves built for larger units (hence different volumes and heat convection in the tank).
