Hot water too hot.

Post by porchdog on 10/7/2011, 5:44 am

Hi folks: I have a 2006 29 RLBS. My problem is that the hot water is too hot and I don't know if there is any adjustment to lower the temp of the water. I use the water heater on elec power only. Like everyone else, my outside switch is frozen in the on position so I use the breaker inside the camper to shut off power to the hot water heater when not in use.
Any help would be appreciated.....Thanks.

welcome to the forum.

I believe there isn't a way to adjust the water temp. It doesn't bother us because we only turn on the water heater just before our showers and to wash dishes. Being adults, we mix hot and cold to get the right temperature.

BUT, if you have children, handicapped or old folks using water in your trailer you definitely have a problem, as they might have difficulty adjusting the water temp.

We don't use our breaker anymore to turn the water heater on or off. As have several members of the forum, we put in a switch right above the drawers in the kitchen counter - next to the gas switch.

They do offer higher temp snap switches. Maybe they offer lower temp ones?? Also if ur not the original owner, someone could of put in a higher temp switch. Each source has its own temp snap switch. So there's one for electric and one for gas.

Doesn't the electric heating element have a wattage on it? I'm not sure where it is, but hopefully someone that has replaced theirs will chime in and tell you where to look and what wattage they have or replaced theirs with.

thanks Mr Mix, but being an adult, my concern is getting the plastic piping too hot coming from the hot water heater to the faucets. The hot water is smoking hot. I have replaced the element at one time with the same type element. I am the original owner and everything else is the same. Maybe a new element with lower wattage is the answer as suggested.....Thanks.

Doesn't matter what wattage element you use, it will still heat until the water reaches the temp of the snap switch. Lower watt element will only take longer to reach temp and have no effect on the water temp.

thanks earl, not knowing about snap switches, is it possible for you to tell me where it may be located.

Wow! That really is HOT! Good luck in finding a solution. What you have sounds dangerous.

I hope you don't think I was implying that you are not an adult.... certainly didn't want to offend. I was saying that since we, Scruffy and I, are both adults and are able to adjust the water temp - as would you or any other able bodied adult. But, if you had young children or adults who aren't able to adjust the temp, then it would be possible for someone to get scalded badly.

My apologies if my intent didn't come across correctly.

They're behind the square black plastic cover behind the access panel. One will be for the gas side and one for the 120v side. I checked one site, you can get the 120v snap switches in 130°F and 140°F. They might be marked and if not, should be a part number on it and you'll be able to find out which temp you have. That site only listed two choices, so I don't know if Suburban has more options or not.

Also maybe your snap switch has lost its calibration and is causing the water to get hotter than it should?? If you have a thermometer that goes high enough, I'd measure the water temp.

Have you tried the water heater on gas only and see if it gets as hot?

One other thing to look for when you locate the snap switch.

To read temerature correctlly it relys on having good contact with the steel tank...

in my world of work, the older Bock hotwater tanks suffer from this. the cheap holder does not always allow for good contact...

I have not looked at mine to see what type of holder it is, but make sure it is tight to the tank and there is no corrosion on the tank...

what I do also is use heat sink compound its like a silver paste that conducts temperature to the snap limit...

you can usually buy that compound at a plumbing/heating supply outlet...

like others have said, it may just have gone bad...they do that...but good contact is a very common problem as well.
