So now you can enjoy time in the great outdoors without having to give up hot showers, washing dishes in warm water, or preparing a hot drink. A built-in lithium-ion battery, which can be charged from your car outlet with the included charger, powers the electric pump for reliably strong water flow. When you're ready to pack up, disconnect the hoses and store everything in the included mesh bag until your next great adventure.

Review: Had my Doubts... But no longer! - This unit is very helpful. That is the short version of what you are about to read. Since this is the first review for this item, I will try to be as in depth as possible. If you are familiar with Hot Water On Demand heaters, than you know they are just that. They provide warm or hot water in about 10 seconds or less. This unit is certainly no different and did not disappoint. I had bought this item when it was $325, and received a partial refund when the price dropped the next night. Then, when my father took it on a trip to keep the water warm on the 6 hour drive home, it quit. I was quite disappointed initially, until I discovered that I had missed a very important safety feature of the unit. What I did not know is that when the pump cannot deliver enough water through the heater, it will automatically shut down. It clicks a few times, and then shuts off entirely. Like I said before, I was disappointed, but then turned very pleased when I discovered this feature. Thanks!
Review: Wife had to take a cold shower!!! - I purchased this a while back in preparation for a trip. It was sketchy in the kitchen and worse out in the rough. Just finally got around to using it in the field and it was a fiasco! Battery wont stay charged and the pilot wont stay lit. I can hear the piezo firing and the burner running but as soon as I move it off of pilot the heater shuts down. Wifey had to take a cold shower and was not happy at all. Challenge now is that desertcart only has a 30 day return window and I am screwed. I would not recommend this product. Update: Coleman claims this is all due to a bat battery with the shipped unit. I am waiting for this to see if it fixes things. Still, the 30 day return window still sux pretty badly.

## Questions & Answers

**Q: How easy would it be to extend the shower-head hose?  Is it a standard-size that I could find an extension for easily?**
A: I bought 3/8th by 1/2 in diameter tubing from Menards. Swapped the hardware. And now I have a 15ft hose for my shower head. Was not difficult to swap.

**Q: can you turn the water flow off at the shower head?**
A: No the water has to be continuous running for the heater to work.

**Q: Coleman is avoiding the GPM on this unit. my question is what else are they not telling.**
A: I sent mine back.  Coleman, flow rate was sufficient, and is largely dependent on the input pressure. YOU are the igniter for the Coleman.
 I chose instead to return my Coleman, and purchased a Triton on-demand.  The Triton is self igniting (D cell batts) and has an internal flow sensor.  So, add batteries, hook it up to a water and propane source, and you have instant hot water when you turn the valve.

**Q: Does battery disconnect for easy charging?**
A: Only the elite model has the battery disconnect.

### ⭐⭐⭐⭐⭐ Camped for 9 days with and it worked perfectly!
*by J***. on May 9, 2016*

Once you get the hang of the safety cut off features, this thing is great! We are a family of 8 and we love to camp for weeks at a time. It sounds lame, but my pet peeve is having to boil water to do dishes. I felt so spoiled on our last trip because all I had to do was run my dish pan full of clean water, turn on the pump and submerge it (sometimes shake it around to get the air bubbles out), turn on the heater, and set the temperature! Hot dish water in just a few minutes! It only "failed" on us a few times in 9 days and each time it turned out to be user error. Once I forgot to plug in the power cord for the pump unit. Once the water level got too low for the pump so it shut off the propane. And once it just died... because I forgot to charge it. But we we found out that we were able to run it while it was plugged in to the charger! From then on we just kept it plugged in most of the time. This use hadn't occurred to me before this trip but it was a nice perk... The bath house wasn't too far away but we have younger boys and I wouldn't dare send them alone so, instead of waiting until my husband was back from the store, I just had the kids shower in their swimsuits right there at our campsite. They loved it! And each time, I had to turn the heat setting down because they said it was too warm. I hadn't expected to have the "problem" with a portable water heater. We did a youtube review: [...]
