Tankless 120V water heater for family of 6

My daughter's family is still having problems with their 6 gallon Atwood propane water heater working inconsistently (less than 3 years old). Now they are talking about a tankless 120V water heater so the family can actually take showers in their TT.

Has anyone found such a water heater that can heat water fast enough for multiple kids to take a shower ?
  • Is it just propane? Consider a 10 gallon that runs on both propane and electric. And yes you can use both heat sources.

    Like a lot of other Jayco owners, our 2016 Jayco Class C came with a Girard tankless.

    For every person that likes it, you'll probably find three that do not.

    We do like it. It was a learning experience how to use it - the Girard does NOT work like a normal water heater. But once we dialed it in - we've got unlimited hot water.

    You need full hook-ups obviously.

    But the point is - there are a few of us with Tankless water heaters in our coaches that like 'em.

    I don't think I'd recommend Girard, however. If I had to do it from scratch, I'd probably look at Truma. Atwood and Suburban also have tankless water heater products.

    We've got one child with specific needs - and the tankless has been a blessing for us.


    Does your tankless rely on electric to heat or does it use propane?
    Thanks!
  • Forget about electric instantaneous water heaters in rvs. Even at 50 amps 240 volts you would only get a moderate flow of hot water. At 120 volts it just ain't gonna happen.

  • Search this Forum for descriptive words like `tankless' and read the reviews. IMHO a tankless heater does not belong on an RV.
    Before I would spend that kind of money I would have a tech look at the present heater. 6 gallons isn't very much with kids taking showers.
  • So they won't shower unless hooked up? Seems very limiting to me.

    I seriously doubt any 6 gal hot water heater is going to be enough to support 6 showers in a row.
    The feedback I have gotten from some members in my local club is to get the better one as the cheap ones didn't work as well as advertised.
