Adjust temperature of water by turning down hot and turning cold on. Hot water will last longer.
Bingo. Best answer.
Good answer to a point. In a former MH despite adjusting the temperature, when taking a Navy shower and turning the handle off to conserve water, when turning it back on, for a few seconds it was all hot. Now this was probably a cheap mixing valve, but that's not the point. If you didn't remember each time you turned it off to direct the water away from you, you got blasted with water that had to be well beyond 120. I forgot once and ended up with burns on my chest and blisters. A WH that only heats to the legal 120 would have prevented that. Why aren't RV water heaters confined to the same specs? So while correct water mixture is a reactive way to prevent scalding, it's not preventative.
1. I always wonder where people think there is a "code" or "Legal Limit" for things. THERE IS NO LEGAL TEMP LIMIT FOR WATER HEATERS. There is a 125 psi PRESSURE limit in most codes for water heaters.
2. The REASON for 130/140 Auto set Tstats on 12 volt DSI RV water heaters is simple. To get the MAXIMUM amount of hot water(mixing cold with hot) they use the 130/140 auto set Tstats.
3. There are RV water heaters that have a 160 degree tstat and that model has a auto-mixing valve on the exit on the back of the water heater that drops the temp to about 120. BUT, it is adjustable and you can fiddle with the adjustment to get hotter or colder output water.
4. Pilot Controlled RV water heaters do have an adjustable Tstat.
5. The BEST solution for the OP is to buy the aftermarket Adjustable Tstat kit. Doug
