hot water heater

[2008FX4]

I was wondering if there is a way to make the hot water heater stay on longer? I run it on LP.and we turn the water off while washing hair and body. But by the end of washing off the water is coming out cold.

Hum,,, I never have a problem. You say you have been RV'ing for a long time. Have you had this problem in the past with other water heater on other RV's? Or, is this a recent issue with a new to you RV?

By the way he worded this, I think the OP is under the impression that his hot water is timed -- that the water heater turns on when there is a demand and then turns off after a certain amount of time, giving him cold water. I am not sure he understands there is a finite amount of useable hot water, whether 6 gallons, 10 gallons, etc.

Is this the case, OP?

No.

Since you've run out of hot water so quickly, it may be due to having the winterizing valves turned the wrong way. That causes the cold water to enter the top of the tank and almost immediately mix with or replace the hot water. So, check your valves.

Second, most experienced RV'ers take "Navy showers", where they turn on the water, get wet, turn off the water, soap up, then rinse off. This reduces the amount of water used considerably.

I think I have them right. There's no arrows saying off or on. So I have to guess.

And we take navy showers. I've been rving my whole life so I know that's just part of camping.

It is a Water heater BTW. The old ones you could set the temp hotter but the new ones are factory set there are a couple of way to pre heat your water like the other poster stated. They make a 110volt on demand water heater that pipes in line it helps or what we have up at the lake on our permanent camper is a roll of pex on the roof of the camper and I put a bypass in and quick connects so it runs through 50 foot of pipe on the roof the sun preheats the water and with a 10 gallon water heater I can take a shower for as long as needed.

The water heater should be plenty if you preheat the water.
