This is an interesting unit. I found one one www.productsthatsave.com for $102. There are at least two other posts about the Marey units here on the forums. My concerns (same concerns outlined on other threads) are:
*This unit is not rated for permanent RV use.
*At the price, it must be made in China. Do we really want explosive gas traveling through something made in China?
*It does not say it is waterproof but it is shown being used outside. Installing this thing inside the aluminum envelope and venting it somehow sounds risky to me.

I like the product and am thinking of ordering one just to see what it is all about--and to have around the house since we are in a hurricane prone area where a hot shower after a week without power is a good thing. My Atwood is on its last leg--old and rusty and about done. Tankless is a great idea if only avoid the freeze problems but making this thing work on an Airstream is chock full of challenges that would have to be overcome in order to operate in a guaranteed safe manner.
I, too, am interested to know where you go with this and how you work out these challenges and will monitor this post for your progress.
If I do order one, I will poke around with it and give you an update relative to its quality.

I'm really appreciating the replies and concerns being posted here. Actually, the tankless unit I will probably end up with is not the Marey, but the EccotempL5. It has production ties to the US (can't get to the details right now-will try to post later) and I have talked to the originator of this one. Plus they sell it at Camping World. I would love anyone who gets this done to post here with results, pics, any problems, etc. I would have loved to already be using one of these, but had to weigh out all and this project got put on hold.

As I mentioned in the beginning of this- I, for one, will not be putting the unit inside the trailer when in use. My plan is to connect to all existing water lines and propane, but to attach the actual unit outside (could have an extra outdoor shower that way, too). We want to be able to remove the unit during winter. I have been told the unit can be on it's side when not in use, so storage inside the trailer while moving is not an issue. I am thinking thru any contingincies regarding rain/hail/snow while unit is outside and how to deal w/wind. Those might be issues to address after they come up?! I am sure my plan is duable w/precautions taken.

Keep the ideas, questions and thought coming...that's what makes this forum so great.

PS Cantrell- the unit in "productsthatsave" is the Eccotemp. It seems the better of the 2 to me!
PS WMarsha - so, you got one? if so, which model? love to hear more!!!!

Even though I am a good ways from installing the plumbing and water heater back into the gutted Airstream, I purchased the Eccotemp L5 via the web today so I could see it, touch it, and figure out a way to make this concept work.

Wish me luck.

Leigh.. I have a couple of thoughts... to actually plumb the heater, I'd just use a "bypass" system that is sold for winterizing the Atwood water heater.. use the bypass feature when not connected to the portable unit, and then turn the valves to divert water to it when in use. I'd also connect some "quick connect" ends to the lines that go to the heater to make it work. Water pressure shouldn't be an issue with the RV water pump... infact, one might find it works better using the pump vs. the land line. With higher water flows from land, the water may not have time to heat properly... the faster the water moves, the harder it is to raise in temp when in contact with the burner.

A termination valve at the end of the propane line with a quick connect would be great... the problem would be finding the proper fitting that wouldn't leak. Maybe a plumbing supply store would have a fitting that's used to hook up a outside BBQ to a house gas line?

I'm intrigued as well! I might use this concept when I get to the systems part of my '63 TW. I actually think one COULD mount it inside, as long as 1) it had adequate air supply and exhaust routes... 2) it needs to be REALLY well sealed from the interior to eliminate CO release inside.... however.... I like the space saving thought of having a pole or stick to mount it too outside.

Good luck!
Marc

cjohannesen - I am soo excited for you (and anxious to hear what you think!!) This will be our next project, altho we may have to wait till Spring now.

Marc - you are on the track that we are. We have a Bypass system in place already, and had it in use when we winterized the old Atwood, which is why we were very surprized when we opened up the trailer and found the Atwood tank split!!?? We are looking to take the old split water tank out this weekend, do a temp. seal on the opening for now and get started next Spring after looking into supplies we will need to make it happen. Now that somebody has purchased the unit we are looking at, we may all end up w/a blueprint to go by!!!

PS I have actually seen a couple of these units mounted w/in some traveling campers. One was a converted bus that had it vented up thru the roof and mounted back on the wall w/a clawfooted bathtub!! Crazy,huh!@!

Leigh,
I ordered the EccoTemp L5 and it arrived Friday. Although have not hooked it up and run it, I took the front panel off to examine the construction and quality. It seems fairly well made and engineered. A concern of mine was that it was made overseas in cheapland. As it turns out this unit is made in Summerville, about 30 minutes from our home here in Charleston. There appear to be some imported parts on it but overall, I am pleased, especially for the price.
Our old Atwood is still functioning for the time being so will probably ride it until it drops but I am definitely interested in how you and Johannsen make this fly. I will go to school on you two!!
My initial thought is to go off the tracks completely and mount it above the tongue area so that it can be outside but with in a protected place. It only weighs 11 pounds so weight not a problem. Means some serious waterline rerouting, though but wouldn't be chancing anything by having it inside the trailer. Just an idea worth fooling around with.
We will keep on with this until we have a good solution.
Good Luck.

Bill - I am really excited that others are looking at this possibility~~
Yes, as I mentioned in an earlier post, I had talked w/the owner/manufacturer/distributor?...all of the above? - a nice guy who gave me alot of info about the Eccotemp and its build. Made me feel that issues could be addressed just a phone call away. Of course, that can change with time, I guess, but I felt that he was in this for the long run. And having it available at Camping World seemed a somewhat good sign. Anyway, I too, am looking forward to others' thoughts and ideas going forward. Our thought is to somehow fashion a bottomless box/drawer that could be fastened/slide into the side of the trailer where our WH opening is and hook the Eccotemp to that. The box may be bent aluminum w/rubber along the edge to protect from sharp edges (I'm thinking along the lines of that yard edging that many use that has a rubber edge that fits over the top to protect a mower edge or someone stepping on it. We are throwing ideas back and forth at this point. I'll just throw this out to you, you might consider taking the Eccotemp out for a trial run just using it on a post and doing an outside shower as the u-tube video shows. Then you can get a feel for temp control and water usage?? You might be able to do it w/your trailer w/out unhooking everything as I understood it comes w/the shower head and some way of attaching to the propane. Might be fun!!

One thing I do remember reading, tho - and this is important...it SHOULD NOT be attached to vinyl as the unit puts out heat and can cause some serious damage. I'll see if I can find and post the warning. I'm looking forward to the creative genius of this group!!

I'm also interested to hear what others are doing

Hey -

I was also considering this idea a while ago.

http://www.airforums.com/forums/f445...dea-54396.html

I didn't get a lot of encouragement but I would love to pursue it. probably next year.

btw interesting to see another 78 Argosy considering the same thing.

thanks for the discussion!

Yes, also considering using the spot where the Atwood lives now with some sort of drawer slide operation. The Eccotemp is a couple inches taller than the current exterior opening (without any slide apparatus) so it would have to go in on its back and then be raised to the vertical position once out which further complicates the engineering--but it is do able.
We have a Rinnai tankless water heater for our home that has been in use for 4 years. It is a great unit--works flawlessly but these creatures make fire and the exhaust heat is pretty warm. Vinyl siding or any plastic stuff near any of these type units would be a bad idea and that information does factor in on how to install this unit best.
We will get it figured out--no real rush but the input from you all will certainly make the end result for all of us better and I thank you.

Hi,
I'm Foiled Again's sister. We don't own any trailer yet, we tent camp and have used the Eccotemp and a Marey. They work very well for conservative water usage. Skimpy showers, dishes etc. but DO NOT use it in a confined space. It makes carbon monoxide just like any other gas fire appliance and the 5 liter is not ventable. It is for outdoor use only.

There are somewhat larger units that can be vented, not sure how you would do that on a camper, but taking your life in your hands to save a few bucks is a bad idea.

Ebay has a bunch of sellers who have multiple types of tankless units. There might be something there to send you in the right direction.

Hope this helps,
Prudence-pb

I found an Ariston point of use water heater at Home Depot yesterday. It's 110v, 1500 watts. It holds 4 gallons and is small enough to go where my Bowen is located. Does anyone have experience with 'point of use'? Will it be enough to take a short shower? Will it tax my Univolt too much if I've got a TV and microwave going? Thanks for the help!

prudence-pb - thanks for the interest in safety. Believe me, that is on the top of the list when dealing w/replacement items for our trailer. That is why I keep saying our usage of the Eccotemp will be outside. When talking to the originator, he indicted that it would be very unlikely to have a CM buildup if the unit was inside, but doors and windows were open. Even so, having vinyl walls in our Argosy would prohibit any kind of attachment inside as I understand the venting up top can get very hot!

If you don't mind my asking since it sounds as if you have been using both the Eccotemp and Marey - do/did you have a preference of one over the other? And, second, did you have any issues when using outside w/wind,rain or snow while in use? If so, how did you correct the situation!

Ag71 - I have not seen or researched that particular unit. We are looking at either the Eccotemp on demand or just a replacement of our Atwood. I prefer the Eccotemp, if doable, to eliminate the hassle of another possible frozen hot WH. We still cannot figure out how ours split as we had a by-pass and thought we had the Atwood emptied. A costly mess!

Hi,
We have the Eccotemp and friends in our group use a Marey. They're nearly identical. They both use D batteries for ignition and heat the water in a coil as you use it. The heat rise is pretty good unless the incoming water is REALLY cold, then you get warm water not hot. Tent camping in the snow is NOT my cup-o-tea so I can't speak to freezing weather issues. (Freezing weather...showering in a 4 x 4 privacy tent...no heat...hmm, not!)

I think the ignition might also be a problem for trailer use. It doesn't stay on unless water is running through it. I don't think the small units were designed for continuous use. Don't know about larger ones.

If it's blustery the wind can blow out the fire but light breezes don't cause any trouble. We try to shelter it from the wind as much as possible but if it's really windy we just don't to use it.

You are correct about how hot the top venting gets. It would very likely melt your vinyl into a slab of goo!
I suspect that heat-wise they really aren't all that efficient but because they're only on during use the net gas usage is reduced. No holding tank to heat.

When we were in Ireland in 2003 our B&B had an electric "point of use" in our bathroom that worked fairly well but again, we had to be very conservative in water usage for both of us to shower one right after the other. Europe also uses 220DC power. I don't know how well 110ac units work and you'd need one for the bathroom and another in the galley.

It will be interesting to see how your adventure in water heaters comes out!
Good hunting,
Karen

BTW, if you store/move your tankless inside your trailer during tranport, place it in a plastic bin. Even though it doesn't have a tank it leaves a little puddle where you set it down. We leave it on it's side in the basement with no trouble but it does have a little water in the tubing so that could be a freezing issue too.
Maybe you could blow it out with compressed air?

Prudence
