Tankless Hot Water

[mmc100bb]

I have a 2014 Keystone Sprinter. I am interesting in replacing my hot water heater with a tankless one. Does anyone have recomendations on the best model ones to buy?

I have a Suburban tankless in our fiver. We love it. No maintenance, nothing to winterize. On our second season with it, trouble free. As long as you have enough water flow to keep the burner going it works fine. If not it will go from hot to cold. There is a learning curve with them. You run the hot wide open to keep the flow high enough and control the temp by mixing the cold in. If you boondock you may not like it.

Good idea.

I engineered a hot water recirculation system for mine that helps.
With what I know, I would stay with a conventional tank water heater.

I remember that!
It would have been a great mod for our last TT that had the WH and shower at opposite ends of the RV.
New TT has them next to each other so hot water is almost instant to shower.

It never fails with these tankless water heater threads, the vast majority of comments are from those who have never had one. Opinions are based on misinformation.

We have a Precision Temp unit in our RV. It works extremely well and has proven to use less propane than the tank style units. These units are dependent on water pressure/flow and incoming water temperature. Any tankless system can only raise the water temperature by a certain amount, so if the incoming water is real cold then the max temperature output will suffer some.

These comments are based on actual first hand use.

I've had 3 RV's 2 with tank system and the latest one with tankless. I was lucky and didn't have any problems but they require yearly service and most other people had a lot of problems. They are way more complicated, on other forums there have been many complaints of problems that people can't seem to get fixed. If I get another rv it'll have a tank system. Much simpler and easier to repair. But at this point in my RV life I can say that about most things after owning a high-end coach with all the bells and whistles. Great when they work a REAL pain when they don't.

Tankless water heaters perform best when water volume delivered to the input is robust and reasonably constant. In RVs this may not be doable, and the result is temperature fluctuations and general bad performance. The one in my house is great, but knowing how they work (and what they need to perform well) I would not want one in an RV.

“Smooth” is a subjective opinion, CMC.

I bet you Diesel pusher rides a whole lot smoother than my travel trailer.

Shocks are a wonderful thing.

Some appliances can not withstand the jarring.

when we had our store people thought the tank less way was the cats meow but it turned out to be an expensive mistake. sure you save space and weight but they don't work that great in a RV

[Lwiddis]

Tankless is thankless. RV manufacturers are discontinuing tankless water heaters. Swim with the tide.

Best water heater for RV....

Small tank one like Atwood or Suburban

as stated, do a search, not a great item in a RV

Do yourself a favor and search here qnd on the other RV forums on tankless water heaters. There are lots of comments, not many very good.
