Hot water not lasting

For immediate relief buy an Oxygenics shower head. It has the pressure you will want but restricts the water flow. You just won't use as much of the hot water on the first shower,,,, making the second more pleasurable.

They really do work.

tell you what. I agree on the cold water thing because I have noticed in the summer time my water control arm on the shower faucet is closer to the middle of the pivot and in the winter it is more towards the hot side of the pivot. this is in my stick house not my RV, but same difference.

One thing is turn the propane on just before you get in the shower and then after you finish turn it off. That way you are not using your propane to keep the water hot when you aren't showering, but keeping up with heating the cold water entering the tank during your shower.

Just a thought but when I first came to Georgia last summer I had dang near unlimited hot water (Depending on the time of day) since the sun warmed it up to shower level while it was still in the hose connecting me to the park. Or so it seemed,, I mean I did not have to wait for the water to get hot in the shower.
(And that last is not exaggerated at all, I really did not have to wait, but I did have to add hot as the sun could not heat it fast enough).

OP well the water in the fresh water tank experiment worked just a bit -- had a little more hot water or so it seemed. Maybe I showered faster than the wife last night? -- using the propane and the electric works great so I think I've concluded the electric elements inside the tank are in need of replacement or repair. Thanks everyone for your assistance.

I was just looking at our hot water heater yesterday due to DW c/o not enough hot water... I could not see a switch to change it from LP to elec. Where is the switch? (1999 Winnebago)

Of course I do realize that a 15 year old anything is subject to quit at the most inconvenient of times...

So is this a fix or replace thing? :h

Some 1999 Winnies did not have electric water heaters. They were only propane. When we replaced our water heater, we got the duel heat one.

As a photographer who still does my own darkroom work I can tell the temp of water will vary by 30+ degrees from summer to winter. With our extreme cold winter last winter and a cool summer we never did get to 70F in 2014 summer and it is a lot cooler already when it comes in the house.

Possible that your electric heating element is wearing out. Ours did and was just keeping water warm, not hot. We replaced and now make it thru 2 showers with no problem. Just hot water should be hot enought you don't want to hold your hand under it for long.

Lucky for me I found this thread.

Whoever said the outside temp doesnt mean anything is WRONG.I can tell you for a fact....it does.Especially when heating by elect.Not as much on propane.My water going in the heater is VERY,VERY cold...Summer time...not so much.But that holds true in most RV parks.Water lines are not buried as deep as normal.
