Does a 6 gal. Suburban SW6DE HWH take a lot of LP

First of all thanks to all who contributed to solving my brake problem a couple of weeks ago. Now I would like to know if using my hot water heater on LP only is going to be costly. I know it will matter how much hot water I use, so here is a typical scenario. Initial heating of cold water at campsite>>>washing my wife and my dishes three times>>>one shower each>>>a few washes of the hands during the day.

It's totally your option, but I've never noticed that my water heater uses much propane. The furnace is the big gas hog.

Here is also a link to using the SWDE, if you aren't too familiar with it:

Iíve lost my scapegoat.
I have nobody to blame but myself.

Doesn't use that much. Furnace yes, a few 30 degree nights in a row can deplete a whole tank of propane.

Thank you lbrjet and wmtire for your insight.
My new to me 2006 FR Surveyor SV210 came with all the pertinent manuals with the exception of the hot water heater. With the link from wmtire, I now have all the info a manual would give me.
Thanks very much

I use electric with my water heater. No need to waste my propane.

When it is shower time I supplement with gas, otherwise I run mine on electric only.

In the 30 years I been camping I have never used electric. I camp an average of 60 nights a year and have never use a full bottle of propane. Maybe if your full time I can see folks using electric. Later RJD

We almost always use electric for hw. If it's included in your site rental why not? Oh and I normally only wash dishes once per day. Paper plates most of the time cause mama's on vacation too.

We got rid of my LP only heater and replaced it with LP/ electric because we are on a seasonal lot paying for power.

We use LP only for hot water.

1) Much faster recovery time on propane;

2) Wattage delivered to water is voltage dependent; the lower the campground voltage; the less watts the electric heater delivers to the water. In the heat of summer, older campgrounds using aluminum supply wires have large voltage drops in their circuits when under Air Conditioning Load.

3) If you use both at the same time, even faster recovery time.
