Hot Water

[pddgm]

The water heater in my fifth wheel seems to get the water extremely hot, is there a way to regulate it? I have checked and I don't see a thermostat?

Getting the water that hot helps to insure the hot water is sanitized. They do make adjustable thermostats, but a better way to utilize the hotter water AND maintain sanitizing is to install a water tempering valve.
A water tempering valve mixes the hot water with cold water and limit the water temperature to the system. Once done, the amount of hot water available is extended AND you have more hot water that won’t scald you.
Depending on where you set the temperaing valve, you could double your available hot water.

I would go with the water tempering valve vs a thermostat you can control. If you go with a thermostat you will reduce the limited water temp you have in the tank. The result will be less hot water for showers.

Suburban uses a preset 130*F t-stat
Hi temp trips at 170*F

Suburban has an Optional preset 140*F


Atwood uses a preset 140*F t-stat
ECO/Hi Temp trips at 180*F

Atwood has a Mixing Valve model...t-stat set for 155*F & mixing valve controls hot out at 130*F
Same ECO/Hi Temp trip at 180*F

Atwood also has an Optional 130*F preset and an Adjustable one (110*F - 150*F)

Thanks for the info. I really need to check mine with a thermometer and see just how hot it is. I know you won't hold you hand under it very long..

Generally the water is hotter in a RV water heater because of the limited amount available. In a home unit, you might have 50+ gallons where a RV is 6-10 gallons. You have to mix more cold with it either with a mixing valve or at the tap to make it usable.

RV Hot water is not intended to be used by itself....end user must temper with cold water
