Hot water

Mods, move if needed.

Spent time this weekend mounting my on demand hot water heater. The price was right ($116.00) and the temp and water flow are adjustable. It runs on propane and the heat shuts off when the water shuts off and heat goes on when the water is turned on again. No burnt out heat exchanger or water too hot or cold. Mounted it under the storage unit and it slides no drawer glides. I hinged it to stand up and reinforced the back with a strip of stainless steel. Stainless hardware and wire rope to make it stand straight up. The shower head fits great in the open door window and with the Kelty car port the showering will be completely private. Water tank goes on the other side of the storage unit and I should be able to get at least twenty gallons in there. I will also run a quick connect line to the rear to plug into my camp kitchen for hot running water there. The pump will be installed on the opposite side of the storage unit and be wired into the rear power with one of the available switches. It looks like it is close to the door and storage unit in the photos but is really quite safe as it only needs to be one inch from other surfaces. It is about six inches away from everything. Tons of fun.

Propane tank like a gas grill. Up to 18 hours on a 10lb. tank

I picked it up local so I saved a bit. You can Google Eccotemp L5 and get a price as low as $116.00.

Finished install

Photos of the instal. Pump in place, plumbing done except for a vent that won't leak, hose to the heater unit and to the rear of the truck to hook into my camp kitchen for pressurized water there for dishes and such, water tank in the storage space, filler hole on top of the storage rack. Last photo is of the inlet on the backside of the camp kitchen.

1.5 gpm flow should be good enough for all my needs except to pressure wash the dirt off... kidding. The 3 gal. tank is a bit small for now but another custom made nine gallon is on the way to take the place of the stubby. I was originally going to put the 3 gal in the camp kitchen but the thing is really heavy as it sits now so water goes in the truck.

Comments welcome as usual.

I used to work for the Walmart SuperCenter in Auburn. Those coiled hoses stayed on the shelf and collected dust for months maybe even years. I'm glad somebody found a good use for them.

Looks great! Is it an inline/on demand style water heater? Or does it need to heat the entire 3-gallons to temp? And if so how long does it take to do that?

On demand water heater that shuts the gas off when the water shuts off.

Can you install a Y valve in the intake (supply) line for using external sources of water? Would the pump have enough head pressure to pull water from an external source?

Looks good.

You have to keep the door open to use the system so there is no build up. If I feel faint when I use it I will know I have to rethink the system.

It works very nice. Not to much pressure to empty the tank and the on off feature for the gas is really nice. Don't have to worry about burning up the heat exchanger. I have not done a real field trial, just the usual driveway test but it does exactly what I wanted it to do.

You know, I never even thought of that! I was so consumed by the onboard thoughts that I got tunnel vision (Unusual for a person with ADD). The pump directions mention the pump should be mounted at or below the tank "For best results" so I never even gave the suction thing a thought. I will now have to reconsider the thought and give that a try. It is self priming so it might very well work.

If not I might have to go to a 1/2 horse shallow well pump...

Thanks Fly Rod!!!

photogod, slick set-up there.

I second the external water source usage question? I know a member who has a on board shower thingy and he can drop a hose into the river/stream/creek/lake/pond whatever, suck water up into the system and shower that way.

That would be the real ticket and not have to carry water with you.

My thought would be to conserve on board water for situations where external sources are not available. Even if the external source is a 5 gallon bucket full of water. That is better than leaving the on board supply with an unknown amount. I am very good at forgetting stuff....

Well, now you guys are making my project last longer. I have a canvas bucket that I have used before when camping so I will have to go get a "T" with a shut off valve and see if the little pump can handle the job. I'll report back tomorrow on the results.

Hang the bucket from your rack and it will be a non issue. One of my water filters is a Pur Camp filter. Scoop up the water and hang it where ever, works great.

That is an amazing price for such a sweet little unit! Great install too!

I'm going to have to get that instead of the heat exchangers that hook up to the engine's water heater hoses. The price is amazing once again.

I'm thinking about mounting mine where the spare tire used to be on a slider to pull it out when it is time to use it... that is dead space anyway under there... or maybe on a hitch with a shower curtain setup to simply "plug" it into the trailer hitch area when you need it.

2 thumbs up for your project!!

Once again, Mr. tunnel vision.

Thanks for solving that problem. That was way too easy. I'll have to start giving you harder problems!

I too have this heater mounted on my m416 and have to say that after spending 5 days camping with it I love it! the exhaust is a lot cooler than I expected but still hot!(dont read i am saying its cool) The best part is my fiance says its the best thing ever. Now she has no hesitations to camping. Nothing like a hot shower thats easily adjustable after a long day of hiking out in the middle of no where. I highly recommend this little unit. Its quiet and ignites using 2 d cell batteries. I originally wanted to install a heat exchanger in my truck but am much happier with the silence of not running my truck to take a shower. I have a 20 gallon water tank I installed under my trailer and 3 people were able to use it for most of the trip but we take quick showers We did have to refill the tank beacuse my fiance liked it so much I couldnt get her out of it. Next time I will just turn it off when shes in there too long I think we took 7 showers in total but that all depends on your water consumption per shower.

Oh yea and the hose they supply with the unit that connects to the shower head is ridiculously short...like 3 feet or something. I replaced mine with a longer hose.

Great job.

Do you think that unit would survive on a roof rack (mounted under a canvas cover) or would that be too hard on it.

Im thinking it would get added to the rig for excursions as one unit, roof rack, RTT, and hot water all in one. (maybe not one piece, but all at the same time).
