    Posted: 05 Apr 2019 at 8:50am
i have a 2017 179 and have not used the water heater yet. I know it can run on propane. We do off grid camping and my questions are:
Do I leave the water heater on (propane) while camping or turn it on and off throughout the day?
How long does it take to heat the water up if it’s shut off and we come back and want to shower?
Thanks,
Woody

We leave the water heater off unless we want hot water.  It doesn't take very long to heat it up; maybe 15 or 20 minutes.  There's little point in keeping it on all the time when boondocking as it just uses up propane unnecessarily.  
Never leave footprints behind.

+1, leave it off till a half hour or so before you want to use it. Turn it off immediately when you're done so its not heating another 6 gallons for nothing.

Exactly like lostagain. We don't use hot water all the time & turn it off and on for the periods when we need it. It heats up fairly quickly, and we will batch our hot water use to minimize the number of cycles.

Do yourself a BIG favor since you haven't used the water heater in your Pod yet. Take the camper and hook up to your city or well water at your home. Then make sure your whole water system is filled with water and that you are sure that hot water heater fills. Turn on your propane and bleed the system using your stove and once its bleed and the stove lights and runs okay turn it off and hit the hot water tank switch and walk outside by it and open its access panel and make sure its running! In about 10 minutes you should feel warm water coming from your faucet and you will know your good to go! There is nothing worse then finding out after the fact when your on a camping trip you have a problem with your hot water heater.

Nothing wrong with turning the hot water heater off and on as others have suggested, but I don't worry about it.  The propane only comes on as needed to maintain the temp on 6 gallons of water, so not very often.  You'll have a hard time measuring the cost of leaving the of leaving the WH on vs. turning it off and on.  If you leave it on the water will be hot and ready to go when you want it.

Some people are concerned about the safety of leaving the gas on.  The WH is very safe though.  Cost or safety, the concerns are about the same as with a home water heater.  Most people don't turn them off an on all the time....

I might turn the gas off when I think about it unless I'm worried about running out of propane when I'd be more careful, but that's almost never. It may amuse someone else enough to do the math, but it's hard for me to imagine cutting off the gas when not actually in use would save more than 2 or 3 dollars a week.

When dry camping, and if it's just one or two people taking showers every other day or so, I'd only cook water when I will be needing it. Remember, the water heater uses a bit of electricity to fire the DSI and open the gas valve, plus the stand-by losses, which means using a bit more propane and a bit more electricity than you need to, especially if you dont have solar and don't have a reserve tank of propane.

If you are hooked up to electric and city water and you will be showering every day and heating with electric, yeah, just leave the electric element on.

Amen, podwekz!

I believe one of the best mods you can do to your camper is to install a hot water on/off switch some where inside your Pod. This way you can just leave the outside switch on the water heater in the on position and not have to fool with opening the heater cover and finding that little on/off switch it has.

Couldn't you just use the 120v breaker inside the converter that controls the water heater element? I have not actually verified it is the only thing on one of the breakers, but I will do that tomorrow.

Yes, you can certainly just use the dedicated water heater breaker. It is in series with the switch located at the water heater tank. No need to add a third switch in series unless you don't like using the breaker to disconnect the ac to the water heater. Some folks don't, its a personal choice.
