Tankless water heater

For those who dry camp I have done field testing on a new tankless heater for Truma corp. Test unit was installed in the spring and I used it several times throughout the summer. They are on the market now. In Nov they installed the production unit. This is one of the best mods I have ever done to a toy hauler. It has saved me approx 50% in propane use. I have taken showers as I do @ home letting it run continuously for 10/15 min and there was never a change in temp. No more reheating the tankful of water over & over. No more waiting for enough hot water. It is propane only and is absolutely wonderful for dry camping.

Cost effectiveness is a relative term.
Just my 2 cents and I'll put away my soapbox.


X2 ...... and very well said I might add.

I have my tankless for boondocking but a real plus for me is it's weight, much lighter than a tank unit.

Camping with hookups is like being at home. Dry camping you get wet, soap up, and rinse. Conserving fresh & waste water. Also dry camping water heater is on propane only. The Truma is propane only. I dry camp 99% so I do save some on propane.

That is why I installed it. Had nothing to do with any ROI but rather a lifestyle choice. We simply did not want "camping showers."


Just curious - what's with the "camping showers"? I heard this from friends who also had a camper. We just started RVing back in June and I've yet to take one. And I shower once a day in our unit with the standard 6 gallon heater. I'm usually in and out in under 10 minutes, and I like a hot shower. Not run out yet so I'm not sure what the big deal is. My only real issue is low water pressure but that seems to vary campground to campground.

HERE is my test report on the Truma water heater.

While this heater may not fit everyone's circumstance, it does perform pretty much like you would want it to. Would I use it for boondocking? Sure, that would be no issue. Would it use more water? Maybe, but not much (if any). Of course if you take a 15 minute shower then you WILL use more water....

If you have questions feel free to ask.

I think that since we all have different circumstances, wants and needs, getting info like this from actual users is very helpful. There are very few things in RVing that are right for everyone but what bothers me are the blanket pronouncements that a thing is bad or wrong based on the responder's circumstance. Electrical line filters/surge protectors are not needed by the majority of campers staying in resort type accommodations but I sometimes go places that aren't 5 star so, for me, they make sense. Water softeners, ice machines and washer/dryers all have a place for people who would like to have them. No one can argue that a dishwasher is more efficient and less costly than a dish pan. My point is that we don't need to denigrate a poster or make statements that a thing is useless based solely on our particular needs.

I agree, but I don't think you will change people. Some people have to justify what they do.

My thoughts don't concern cost,wants, or needs. But more on the advantages of a tankless heater vs. a typical DSI LP/electric heater.
In the end I see no advantage of having a tankless. My 10 gallon heater delivers all the hot water I need, no fuss no muss. No LP needed when at a electric site. Maybe if I were running out of hot I'd consider something different but the 10 gallon heater keeps up with my family's use without issue. I simply would not benefit from the tankless.


I have only camped in a campground 4 times in 16 yrs. Elec is not an option. Propane is sometimes 50 miles away. I like my Truma

Love this!^^^^^^^
May the Mods grant me the serenity to accept the opinions of those I cannot change,
the courage to offer input to those who are open to another way of thinking,
and the wisdom to shut up whenever I get too caught up in my own misconceived brilliance.

I like the idea of tankless I have one at home. But with my 10 gallon gas electric heater in my RV I never run out of hot water. I can take as long of a shower as I want to and realistically not run out. I'm not sure I see the advantage of having tankless maybe to save room? I would not benefit from unlimited capacity because I currently have all I need. Is running out of hot water really an issue for those with 10 gallon or larger heaters?

Very good report. I am not as articulate as you are but I experienced the same during my field testing before it went public Thanks for the backup. Maybe I can post again without being flogged.
