Auxiliary Hot water Idea

[getsum]

So I've been toying with how to get more hot water when we need it and not endlessly heating water for now reason.

I'm thinking of adding an electric tankless hot water heater for on demand usage. I will keep the electric/propane 6gallon unit that came stock. However, I want to plumb in the unit (with the ability to bypass it when not in us and revert back to stock heater, or even stack them to reduce the heating load on the tankless unit)

My trailer is only 30 amp service, so I'm never using the 50 amp supply from the pole. We don't plan on traveling with this trailer, if ever.

My thought is to run the 50 amp service to the entry side of the trailer via 50amp extension cord rated at 12,500W. Then install a matching receptacle on the outside for ease of connection. Then plumb in the aux heater inside above the stove unit. Add valves to bypass or place it inline.

I'm an electrician so it doesn't scare me to do this myself. Doable? Thoughts?

Why don't you change out your normal tank to a 12 gallon .
I think it maybe cheaper and less work.

Not enough room behind the current tank.

You might want to use the 110 volt heater.

FWIW, I have found that if I use BOTH the electric element AND the propane at the same time, I can keep the water hot enough for extended showers with a 1 GPM head. You might want to try it before doing the add-on.

I'll give it a go this weekend. But I just can't seem to ever have enough hot supply for my family. Just gets old waiting for the re-heat times.

Have 6 gal gas / electric in all trailers we have owned, 3 kids, DW and I have all showered 1 after the other with a 5 minute or so wait between and have had plenty of hot water.

Submarine Showers.
Unless you have an endless supply of water from a hookup, it is time to teach the kids how to do a submarine shower.

What you can do is get rid of your electric/LP water and install a LP endless hot water heater in. Cedar Creek is starting to install propane endless hot water heaters in. That way you never run out of hot water. Look at adventure.net

Attwood makes a on damand hot water heater that is a direct replacement for your RV unit and about the same cost as a electric unit. And will use less gas in the long run. I am thinking of changing mine over.

Has anyone installed the Camco hot water electrical heater unit to be able to use 120V to heat up the hot water instead of LP? I see it for sale at Walmart for $65. I just viewed a couple of YouTube videos of guys installing them without fail.

At that price it sounds like a single spigot unit for a cup of tea, coffee or instant Soup.
