This past weekend, we left our hot water tank turned on all weekend. Our old TT just had a gas hot water tank but the new one has both gas/electric. Was much easier to leave the electric element on instead of using up my gas and turning it off and back on when we need it. Who leaves their tank turned on all the time?

Waste of electricity to leave it on all the time. Plus sometimes they get a bit too hot and if the overheat censor fails it will start hissing out the relief valve. Plus wasting your element.

On when I set up. Off when I break camp. Always have, always will.

Well.......for 7 yrs. of full timing the water heater was ON (except on travel days)I like/want HOT water when I want HOT water.....not 20-30 minutes later.Just like my home water heater......ONAnd just like home water heater it has a normal temp t-stat, a high temp t-stat should normal fail and a T&P Relief Valve should both normal and High temp t-stats fail.Redundant safety measures...........just like the one in house. Dang if they haven't thought of everything :B

Hi,At campground with electric the water heater is running. For boondocking I'll turn it on when I'm using other heavy draw appliances. It seems to 'coast' quite well for about 12 hours.

I turn mine on as soon as I'm hooked up to shore power. Turn it off when I pull the plug.

We turn on the water heater (either from solar/batteries combo or propane depending on insolation) as hot water is required. We place a container under the tap and let it fill until the water is hot. We use that water for tea/coffee/cooking or just put it back into the freshwater tank via siphon hose.

We are generally boondocking when not mootchdocking (staying in the backyards/mountain sites of our kids. We seldom boondock less than two weeks and then only come in to wash clothes, replenish foodstuffs, and drain tanks. See a lot of wildlife with solar autonomy aka no use of generator in two years.

Had I known how dangerous this RV thing would be I would never got my family into this. Refrigerator fires, exploding water heaters, self destructing china tires, and the risk of who knows what disease at the dump station.

I think we are going back to a tent and 5 gallon bucket this year. :)

Old Biscuit you have it!Before retirement had Ga master plbg lic,also helped operate boilers (steam generators) for a short time in my young days.Charles. PS I think most if not all water heaters have an ECO if all else fails(energy cut off)

So......then do you turn your Water Heater off at your sticks snd Brick...?????..and just turn it on "when you use it"???????:h

Essentially, yes. I have an on-demand water heater in my home. Electric went down by about $20 a month, and we never run out of hot water (a nice thing, with 5 people).

I often boondock longer than two weeks... And water is a lot further than an hour away at a lot of places I go... Why would I want to go where there is water and people anyway? Boondocking that close to services hardly qualifies in my book. Might as well have FHU and neighbors.:B

We only turn heat with propane as required. It only takes 10 minutes or so to heat the water and can see no reason to leave it on overnight.

We do run the Dometic fridge on AC from battery/solar 24 hours a day on these great solar days at our older son's place in mountains of northern NM. Was not sure about using the solar/battery suite to heat the water but decided to try it and as Pianotuna noted, it does not take that many kW-hrs to do this. The power rate is fairly large, about 1.7 kW but it does not take more than 15 minutes to get to temperature.

Running both water heater and fridge, plus extensive use of microwave runs us 7 to 8 kW-hrs a day. If days are not sunny (it is supposed to be thunder storms tomorrow) than we change back to propane. Propane is not expensive but it means 1 1/2 hour round trip to Las Vegas, NM to fill tanks (we have 6 x 20# canisters) and photons are free.

Life with solar means changing energy management to suit the sun.

Boondocking is whole different animal. You have to manage your electricity quite diligently.
I boondock 100%.
Electricity is easy. Water is not. That is the limiting factor for us. Sooooo, I like my water heater on all the time. This actually conserves water.

We boondock/drycamp/mootchdock 95% of the time. We have only tied into line power once in two years and have not used the generator once. We have been in a couple of RV parks in past year when visiting relatives near big cities. We only tied into line power the one time when we were in shade and it was 103. We can use a/c for 3 to 4 hours with solar/battery suite

Dry camp - Forest Service/BLM/COE CG with possible table and now water except a possible water point

Boondock - dispersed camping on public lands, hopefully, no one else around but wildlife

Mootchdocking - set up in one of our kids' yards when visiting. Do not hook up.

We have lasted six to seven days on battery suite in heavy tree cover on Olympic Peninsula and in Cave Creek (Stewart Campground - dry camping) in the Chirichahuas. Changed energy management to: inverter off except to use microwave or watch Mystery Theater on our DVD, and ran water heater and fridge on propane.

We did harvest 8200 W-hr today. Tomorrow will be storms and power management changes.
