How long to heat 6gal?

I just got this AS in the barn and fired up the H2O heater to take a shower.
I can hear it "whooshing" through the bulkhead and it works fine....flame is a nice healthy blue.
BUT it does not shut off in the time I think it should and the water is very hot and the red light goes out on the wall switch in the bathroom....
BUT it keeps going
I'm afraid of damaging it if I leave it on more that a minute after the shower.
Nothing in the manual.
Advice?
Thanks

The red light on our bathroom wall stays lit only until the ignition has effectively taken place and the HW heater continues to come up to temp. (ie, a couple minutes? more? less? not sure -- weather hasn't allowed us back into using our Safari yet).

We turn our HW heater off overnight to avoid unnecessary flamethrower sounds during the night. It's turned on first thing in the morning. My sense is that it takes maybe 10 minutes or so to come up to temperature.

I've had it take up to 30 minutes for the water heater to switch itself off. The water is usually "hot" in about half that time.

Our switch only lights for a sec until it ignites. Might have a stuck switch but Check the thermostat on tank, if it is like household tanks it could be turned beyond the normal 140 so that more hotwater was available for previous owner. Ours doesn't have a setable thermostat just wires connecting and no dial. They do have a blow out valve which would relieve pressure, but steaming water could be a health hazard.

on ours, red light comes on when you push the switch. red light goes out when water heater ignites. after that the burner cycles on and off as needed (from the thermostat). if, for some reason, the heater does not ignited the red light comes back on. so switch on, no red light is the operating mode. check the thermostat. some are actually adjustable. some are not. We run the heater for about an hour in the morning and about an hour in the evening. there is some deadband in the operation. the water overheats before the flame goes off. then it has to cool under the setpoint a bit for the heater to cycle. more deadband means more overheat at first but fewer on off cycles. I had to replace my thermostat.

Hello Bill. This is Howard Hodges. Thought I might see you at the state rally in Crossville a couple weeks ago. We are staying home this summer. Nothing planned except Jonesboro story teller this fall.

We only turn our water heater on as needed. In the summer it takes 25 - 30 minutes. In the winter it could take as long as 40 - 45 minutes depending on how cold air & incoming water are.

My water heater is gas only. Firing it up with water at ambient temperature of around 72 degrees it will run for maybe 20 minutes or so before shutting off. Never really timed it.

I've never had it kick on during the night or any other time I know of unless washing dishes or taking a shower. During those times the water heater only runs for maybe 10 minutes after finishing the shower or dishes.

I was surprised at how fast our's came up to temp, about 6-8 minutes. It does not continue to run after we shut it off.

During the summer mine usually takes 10 minutes, in the winter longer. Never turn it off during the winter. Saw a neighboring SOB get frozen Niagra Falls out the side of his rig because he wanted to "save propane". Betcha a new water heater costs more?!

If yours takes a really long time to heat, ask yourself "How long has it been since I drained the thing?" Pulling the bottom plug and letting the calcified stuff drain out about once a year can help the heating process. Of course if you have the 10 gallon heater it will take longer.

Hello everyone:
Problem solved with your help: First clue (I used to be an electronics tech) was the light staying ON until the thermo. told the circuit that it had reached high temp. (Obviously backwards).
I just paid some major bucks for a complete rewire of my barn (to run the well/filter/Septic field computer(no kidding),WD/kitchenette (AND RV 30A plug)
I assumed they did it right as it was permitted and inspected WRONG!
Plugged in the polarity indicator and showed Nutral and Hot REVERSED. Boy was I pissed off. Bunch of Bozo's Hope nothing damaged?? But everything seems ok....Glad I had'ent fired up the Furnace yet!!
Well there ya go. PS it takes 12 min. to go from 50F to cut out.

I hate it when that happens.
Usually, having the polarity reversed isn't going to hurt the appliances, especially the 12v ones like the furnace. The big concern is that your Airstream grounds itself through the outer skin and body, and having 120 volts on it (known as being "hot") could have had shocking consequences. At least it's fixed now.

I thought that our WH burner stayed on too long as well, so we had it checked out....

Everything checked out ok (although I thought the water was a bit too hot). We usually turn the WH on about 20 minutes we need the water, and turn it off when we are done.

I have found the water to stay hot for hours after the burner is off (for dishes ok -- not for a shower). One of the great advantages of the inside switch is that you can shut it on and off when you need it.

As noted on the earlier posts..... the light should only stay on if the burner does not light.
