Tankless water heater

Hello friends.

Our new to us 2007 Fleetwood Revolution LE 40E has the standard 10 gallon water heater. This spring we are going on some long trips and I am wondering is there is a value in a On Demand Tankless Water Hester?

Opinions? Models? Success or Failures?

Thank you.

I'm thinking about the same thing...

Looking forward to hearing some ideas.

From everything I have read the Truma seems to be the best "on demand" hot water heater. That being said, I have a Truma in our coach and to be honest, I'd much rather have a 10 gallon DSI. The reason for my opinion is, I just don't see the Truma having a trouble free lifespan of 15-20 years like you can have with a 10 gallon DSI.

Thank you Paddler for the feedback.

Thats fine, but does it work? Does it provide uninterrupted hot water?

Heck...we may not last another 15-20 years either.

No idea if the mentioned tankless heater will work but one thing to check is the temps it says it will achieve based on the ambient temperature of the water coming in. If you do a lot of camping up north where the water temps will be lower it may not have enough BTU's to bring it up to a hot enough temp.

Just built a new house and decided to go with a tankless. The one I finally installed was +190,000 BTU with +98% efficiency. My wife does dog grooming and sometimes runs bath water 6 hours a day plus loads of laundry. We've had 6 guests, 3 taking showers at the same time and have never run out of hot water.

One thing to think about also is the required service on a tankless, I flush mine with vinegar every 6 months. I also have a 200 mesh screen on the outlet of the hotwater heater to capture all the calcium that drops out, which would go to the faucets without the screen.


Also, when I pull the front cover off to do a service there are numerous intricate circuit board, sensors, etc for safety purposes. I would assume that all new water heaters have this, no idea how they would hold up in an RV with the bouncing etc.

We have had an Atwood tankless for 5 years and have been very happy with the ability to have endless hot water at any time and would not want to go back to a tank type heater. The Atwood hasnít been without itís problems and it has finally developed a leak and we are going up to San Antonio on Thursday to hopefully get the Truma system installed. I really doubt that we will have this coach for another 10 or 20 years so we will let the next owners pick their favorite water heater.

Not in a motorhome but my experience with tankless hot water heaters is unless you have soft water it will be a bundle of trouble.

I may be speaking of old history since this was 3 or 4 rv's ago, but we had a tankless in that fancy 5'er and it was actually dangerous... we wouldn't even think about putting the grandkids in it when they visited. It would go from cold to near boiling in an instant!
The mfg volunteered to come to Fort Worth to add a rheostat for us to adjust the temps, which helped a bit, but still the temps have so many variables, incoming water temp, pressure must be consistent, etc... ended up replacing it with a 10 gallon that worked fine...
I will say this was maybe 10 years ago and the technology has probably improved a bunch, but with variable pressures at campgrounds, I'm sticking with the tried and true.

Hi Pete,

Who/where in San Antonio installs the Truma?

Thanks.

Chuck

Yes, our Truma will give multiple people a shower one after another. But...
Our Truma has been very sensitive to water pressure and water flow rates. Where we are currently camping both are good but even so if you take a long shower the water temperature will do some 20 degree swings on you. Prepare for a blast of cold water if someone else in the coach turns on a faucet. Doesn't matter if they turn on the hot or cold faucet, the drop in water pressure will give you a blast of cold water.

Our Truma is a Plus model so it has electronics that monitors the flow through the Truma and will notify you when you need to de-calcify the unit. Truma sells de-calcification tablets to use in cleaning it. I clean ours annually as we are not full timers and therefore we haven't triggered the Truma's time to clean warning.

One caveat for a tankless is that you are forced to maintain a constant water flow. This is problematic for extended boondocking when trying to do conserve water. A Navy shower would be quite the adventure with a tankless, I'm thinkin'.

I've not actually used one, just going on anecdotal evidence from folks that do quite a bit of boondocking, particularly with a class b.
