Running Water heater on Gas vs. Electric

The ease of delivery on electric will win hands down.

Electric:
Assuming you meant $0.124 dollars per KWH!
$1.00 buys 8016 KW (100 / 12.4); 8016 watts * 3.41 BTU per watt = 27419 BTU per dollar.

Propane:
$1.00 buys .23 gal of propane (7.1 gal in 30 lb. tank / $30.00 per tank); .23 gal * 95000 Btu per gal of propane * .75 (guess of efficiency) = 16862 BTU per dollar.

In your case propane is significantly more expensive than electric. Where I am, last tank I refilled was about $20 for 30 lbs. just about a wash between the two for me.

Depends on the site I am parked on.

Where I am for the next year or two I pay flat rate per month,, This includes water, sewer, electric and Wi-Fi but NOT propane.. SO, ELectric it is.

11 miles away are two more parks I considered, Less per month but I pay for power..... In those parks I'd use GAS.

I might add, the park I'm in (Cathead Creek Ranch RV Park) is only 24 sites, no trees, and frankly has little to recommend it.. But I really like it, Like the owner (A preacher) like his Cowboy Church (Which IS an attraction worth attending often) and like some of the people here and nearby.

The other parks are closer to my daughter though I pass them on my way to her place.

The answer for which is cheaper depends totally on what you're paying for each fuel type, and the efficiency of the water heater. According to a web site I use, the energy content of a gallon of propane is the same as 26.667 kWh. I'm fairly confident the efficiency of an RV water heater on electric is reasonably close to 100%. On propane I'd start with a guess of 50% because a lot of the heat exits to outside the RV. Based on all of this, if electric is 10 cents per kWh, the propane would need to cost 1.33 per gallon to break even. I'm assuming a DSI water heater so a pilot light isn't a factor. Personally, with the ignition sequence sometimes being a problem, soot buildup issues, and the heat on the outside water heater grill, I'd use electric whenever it's feasible.

I don't worry about it. I run electric when at the campground, unless I need a quick recovery, then I run both at the same time. At home, in my driveway, I usually use gas (when we need hot water.) Only because it heats faster than electric. I don't know which is cheaper. Doesn't matter to me.

One does not have to refill electric therefore thats how we run 100% of the time but we do not full time.

If electric is metered...then it depends on what electric costs per KWH vs what propane cost per gallon.

I agree. Remember that at home you're probably paying more of a bulk price.

If we're in an RV park then we leave it on electricity. If off in the sticks, it's of course on gas when we get up in the morning. Let it heat until hear the burner kick off and you've got at least warm water all day.

I'm metered at 0.124 cents per KWH and per gallon not exactly sure I know I just paid just over $30.00 to fill one of my 30lb LP tanks.
