Water heater question.

[NHcamper]

I have a 2010 Starcraft 175rk. This is my first TT. On our second trip I fired up the water heater and my wife and I took showers, no problems. About 5-10 minutes later we were about to go for a walk and I noticed the burner on the water was still going. I waited another 3-5 minutes and it was still roaring away. I shut it off fearing it blowing up. Is this normal? Its doesn't hold much water I wouldn't think it would take to long to recover from showers. I also assume most people light it and keep it ( the pilot ) lit during there stay.
I've searched but no luck. Thanks in advance for your reply's.

The burner will shut off when the water reaches the thermostat setpoint. It takes 15 minutes for me to get 2.5 gallons of water to boil on my 29,000 btu stove so if your 6 gallon water heater takes 25 minutes it's probably doing ok.

If you haven't done so already - check your temperature setting. If you can live with a lower temperature setting it may significantly reduce the run-time and conserve propane.

It takes a while to heat up the 6 or so gallons in the heater. The thermostat should shut it off when it reaches temp, and it has a relief valve which should open up before it would explode. Leave the pilot light on or you will have to keep re lighting it every time you want hot water.
