Propane or 110 hot water

We pay for elec. at our rv park. Is it cheaper to run h/w on elec or propane?

Electric. Unless the park is padding the bill.

It might depend on what type of water heater you have. As an example, the PO installed a hot rod element in the water heater that only draws about 4 amps. heaters that are designed for electric draw much more.

At the end of the day the difference in cost I suspect is minimal.

Electric id say, most rv parks charge double or more the going rate for propane. What are they charging you per Kwh?

If you turn them both on the hot water reheats much faster. The difference in cost for electric or propane is not enough to worry about.

I use electric when possible. I don't like to listen to the jet blast propane heater day or nite.

Gimme' the nice quiet electric heat.

A rough rule-of-thumb is to multiply the cost of electricity X 18. If the result is over/under the cost of propane per gallon you have your answer. Propane RV burners are around 70% efficient, electric is virtually 100% efficient.
electricity_ 1kw = 3,414 btu
propane_1G = 91,890 btu
factor in your propane efficiency % for your water heater.

I run with both; as previous poster stated, the water recycles much faster. Plus the electric keeps the water hot without using any propane.

I suppose running the hot water on AC will preclude having to get the propane tank filled.

I'm certain that when both my switches are on the propane only activates if there is no electricity. I think the recovery speed is in your head unless your system works different than mine! Lol

I use both gas and electric-they work in tandem.Must be in my head as I can hear the gas operate when on.Recovery is much faster.

My gas doesn't operate when the electric switch is on unless it's unplugged from power. How do you get them to both work at the same time?

I do not have a copy of it but somewhere on the forum (All 3 of the forums I frequent) is a mathmatical formula that answers the question.

In some cases, Propane is cheaper.. In my case. it is not (I do not pay for power).

Home is where I park it!
