hot water heater upgrade

currently we have an LP only suburban 6 gallon HWH
its only effective when your not around electrical service and don't hve a generator attached.

We have a seasonal which like everyone else we pay for power.

we recently purchased a Suburban 6 gallon HWH that is both propane and electric.

problem is that we have the propane hot water heater switch already integrated withthe tank level check switch.

should i keep that and pick up a second switch or bypass that integrated switch and try to locate the dual switch for the new hot water heater?

any one thats upgraded or has researched this please let me know what worked for you or someone you know or what you've found out.

so since i had posted this asking the question on what i need to do (purchase a dual switch and bypass the existing one or use the existing switch and order a single electric switch with light) I've had 91 views on the subject and no reply in my question.

either tells me that no one has replaced the LP only tank to a dual tank or ... two other options.
everyone has the dual tank already with dual switches
or
no one really knows what to do in this case.

Would it be to inconvenient to just use the switch provided on the new water heater?

No wires to run, the one there for the gas side would need to have a wire nut on the end and taped/wire tied out of the way unless you plan on using the gas side later.




Oh yah, in my case I did not see this thread till today......

Not quite sure what you're asking about. But I didn't want to have to go outside to turn on the electric heater, so I added an inside electric switch with a pilot light in my bathroom (where the HWH is located) so I'd know when it was turned on. Depending on where your HWH is located and where your gas switch is located, installing a dual switch could be a real problem, given you might have to run wire some distance. My switch is right by the water heater.

See pics in Post #4264 here:

Here's the wiring diagram:

you can use your existing switch for the new h/w/h then add another for the electric side a atwood is a 12v circuit to turn on the ele if your going to up grade get the atwood over the surburban it's aluminum over steel

Why not install a residential type switch and forget the RV electric switch? As others have done, I added one with an indicator light on the face of the kitchen cabinet. I did this so I wouldn't have to go outside or to the circuit breaker panel to switch the water heater on or off. You run a 120 volt AC circuit to the switch and from the switch to the water heater.

Be aware that if you use a switch with an indicator light, you have to run a separate neutral for the light to work. This means you need 14/3 with ground cable from the circuit breaker panel to the switch. You only need 14/2 with ground cable from the switch to the water heater, but it doesn't hurt to just use 14/3. You just cut off and tape up the unused conductor.

New one doesn't come with one lol
Which is our dilemma.

The existing switch is for the propane only and new ones are either electric only or dual.
Either way I will have to rewire a new plug and at least one style of switch

Since you'll need to put the electric outlet that you plug the heater wire into near the HWH, I'd still put the switch near there and forget a dual switch.

There is no dual switch. On the gas/electric, the gas ignitor switch is in the control panel and the electric switch is on the water heater. It is a rocker switch that you need to turn on and off, especially off for if you leave it on and don't have water in the water heater it just takes seconds to burn up the heating element. I know from experience.

wbonta: Look at posts 4 & 6 - installing your own INSIDE switch so you can leave the rocker switch on the HWH ON and turn the element off and on from inside.

Some folks have installed a dual switch where the gas switch and this remote electric switch are together.
