For anyone whose world view tends toward the 530nm
wavelength, Girard (the maker of what some consider to be
the finest RV awning in the business), has introduced an
induced draft LPG tankless water heater.

I saw it at their booth at SEMA yesterday, and it's an RV
specific product - i.e., no cobbling up a bunch of parts
intended for another application, looks to fit into less
space than SOTI Atwood models.

Here's their info on the Web:

http://www.greenrvproducts.com

(Oh yeah - almost forgot - the guys from RareParts.com were
there, and they are familiar with the GMC front suspension.
Mike Miller mentioned them in a post a little while back.
They supply the suppliers like Cinnabar, Golby, etc. From
talking to them, they could be persuaded to do more if they
had a more complete idea of the kinds of things needed. Not
just ball joints, and tie rod ends, and relay arms - that
kind of thing. They might be interested in developing a
weld-in-place lower control arm reinforcement part, or who
knows what else. Mostly a matter of the size of the market
potential.

The GMC suspension parts are not listed on their Website nor
are they in the general catalog. They said one has to ask
for them specifically.)

Looks like a great unit, but at ~3x the price of EcoTemp, and Girard doesn't quote any gpm specs, kind of makes you wonder what you're paying for other than bragging rights to having a new technology...

The installation/owner's manual says it requires a minimum
delivery rate of 1gpm per faucet it is supplying to operate
properly. That seems to mean that it can heat all the water
you can feed it at normal RV pressures and flows, forever or
until the gas runs out, whichever comes first.

The manual clarifies things that the brochure/cut sheet
doesn't get into.

Pricey? Yeah. But nobody ever said going "green" would be
inexpensive.

Their literature also says "available exclusively on new (2010)

Still, their biggest claim to green is that they only use gas when water is demanded. But all tankless heaters do that. So that's just hype. The only valid claim they might have would be in the efficiency of their combustion design, which they claim as over 90%. Fine, but would need to see similar specs for other models on the market to make a fair comparison.

Lets not be so negative. I like it, I want one, and I need one.

Now to the less positive. Aside from cost and availability, my concern is the 1 gallon per minute minimum.  I take low volume showers at much less than 1 gallon per minute.  I use a small stream of water due to limited holding tank capacity when dry camping.  Two showers ago I found myself standing in water as the holding tank was full.  Then when I flushed the toilet to empty it of shower water, did I get an unwelcome foot warming surprise! 

Cost might not be as big an issue as low volume.  I would want to know if my warranty voiding modifications to keep it running at less than a gallon per minute would work without creating a boilover or fire hazard.

Well I positively want a tankless heater too. It's been on my list for awhile. But the research I've done shows the Ecotemp L10 seems to be a much better buy. About $230 discounted last I checked. Specs I've seen online have been contradictory. I've seen one site that claimed it was 75Kbtu, another said 69K. Both lots more than 27-34K of the Girard. Even cheaper is the EZ101 at $135 for 42Kbtu. Gotta ask yourself how paying 4x that for less performance could possibly be worth it. Then there's the Marey 10L at 69K for $220.

Here's the photo site for Ray's installation of an Aqua which I think is also about $250 or less.
http://www.gmcmhphotos.com/photos/showgallery.php?cat=5266

I'm just sayin there are lots better buys for our GMC's out there than a product positioned for new RV's where they can pull a price that just doesn't look justified for the performance.

Hi Toby and others,

You can compare the flow performance yourself with a few simple
calculations.

The heaters are rated in BTU/HR input, you multiply that by the efficiency
probably 70% to 90%, (the remaining 10% to 30% goes out the exhaust) then
divide that by 60 to get the BTU/MIN.
1 BTU will raise the temperature of 1 pound of water by 1 degree F, a gallon
of water weighs 8.34 LB
Multiply the GPM flow by 8.34 and divide the BTU/MIN by that figure (the
weight of the water flow in 1 minute), this will give you the temperature
rise at that flow rate at a specific BTU/HR input.

Example: 34,000 (BTU/HR input) X .9 (efficiency) = 30,600 BTU/HR / 60 = 510
BTU/MIN

Example: 1.5 GPM flow X 8.34 (LB/GAL) = 12.51 LB/MIN Now divide 510 by
12.51 this equals 40.76 degrees rise, so if you started with 70 degree water
the heater would be capable of producing 110.76 degree water continually at
a flow rate of 1.5 GPM

If the flow rate was half the rise would double, if the flow rate was double
the rise would be half.

Hope this is helpful information.

J,
We just got an Aquah 6L for $160.00, and will be installing it this winter like Ray and a couple of others did.

Tankless water heaters:

There is one feature? of a tankless heater that is not in the advert literature and that is how much flow must occur before the burner lights.

The all tankless units will flow unheated water for some period of time meaning that if you stop for a "soap up" and then restart you will get a surprise! Yes, there is some heated water retained in the core but it cools very rapidly.

Also the controls are much more complex and fragile than in a traditional heater, something to consider in a wilderness machine.

The good thing about them is an unlimited supply of hot water once they are fired up, but that really may not be a good thing when your dry camping.

I installed a tankless unit in my house and I would have removed it in the first week but my pride forced me to keep it! I installed a 10gal electric water heater as a buffer after the tankless so that I could have hot water immediately when a faucet was turned on and now the wife is happy with my $2,500 water heater. Let's see, 150 year payback!

I put a 6gal Suburban gas unit in the GMC.

Good luck

Gil

I installed a tankless unit sort of following Ray's model. The installation went fine, but showers are an issue. If the flow is too low, you can end up with cold water. I'm still working on it, but haven't got it solved. The shower shutoffs designed for homes tend to leave a small amount of water running, but it isn't enough to keep the water heater on and when you push the button to turn the flow back on -- WOW -- what a surprise until the pipes get full of hot water again.

Recirculating loop with pump and check valve? It would keep the flow rate up, the burner would cut back because of the input temp to the WH. That high input temp may not be allowed by the WH specs. Just a thought without much background.

You guys are a lot smarter than I am but I will say, I have never had a "surprise" after soaping up in the shower. Water is always warm. We installed it for dry camping and only use it for showers. We have the electric heater for when we are plugged in to a/c.

Considering the Girard is a direct retrofit, PPL has it for $560.....not bad if
a person doesn't want to jag around and just do a replacement. If I recall the
last one that was a retrofit that I saw was a Precision Temp and those things
sell for around $900.

J,
We just got an Aquah 6L for $160.00, and will be installing it this winter like
Ray and a couple of others did.

It should work Jack, we have a switch on our shower head that shuts if off
completely and when we turn it back on we never get cold, always steaming hot
water. Play with the adjustments more.

I installed a tankless unit sort of following Ray's model. The installation
went fine, but showers are an issue. If the flow is too low, you can end up
with cold water. I'm still working on it, but haven't got it solved. The
shower shutoffs designed for homes tend to leave a small amount of water
running, but it isn't enough to keep the water heater on and when you push the
button to turn the flow back on -- WOW -- what a surprise until the pipes get
full of hot water again.
