I got this one mainly because it had 1 day shipping that I needed, but I am happy with this unit. The Winter/Summer dial just changes if two burners come on, or just one. So in winter mode you will get hotter water, if you need water over 100 degrees, otherwise summer is nice to keep the water in the 90s range. This is attached directly to a camp sink, so we use summer setting for washing hands and stuff, and use winter setting to get hotter water for washing dishes. Beyond the summer/winter setting, you can change the flame height using the heat setting dial to get the exact temp you want. The digital display is something my old heater did not have, and it is handy to have that available. It has not failed to light for me when turning on the water pressure, and we used it several times a day for over a week when camping this year. I did not see how long it will heat, but I know my old one had a safety feature where it would auto turn off after about five minutes. Based on the reviews saying it turns off, I assume this heater has that feature as well, and that is not failure, it is a safety feature. It was easy to move my fittings over to it, and they supply the teflon tape for the connections. I used the tape for both the gas and water line fittings and I had no leaks. There is an adapter supplied to allow a garden hose fitting for the water in. They assume you will be using the showerhead, so they supply no adapter for the output to go to a garden hose, but I already had those adapters from my old heater that I moved over. All in all, the price was good at $100, since it was generally about $50 less than other camp heaters available. I don't see where the more expensive ones give you anything more than this one, so it seems like a good deal. I had paid almost $200 for my old CampLux heater when I bought it years ago. Time will tell, but I hope to get several years out of this one as well. Review: It ignited but doesn’t stay lit what could be the problem? - Had it for four months I know it won’t stay lit. Everything works as it should and once the tank is, turned on ignite, but doesn’t stay lit shut back off. What could be my problem to fix this?

Or does it have to hook up to a faucet?** A: No the water needs pressure behind it to work. So no to a bucket. **Q: Is the shower head removable so the heater can be hooked up to an off grid water supply and pumped into a kitchen and bsthroom shower?** A: Yes (used this as 1 month temp while waiting on new gas line install) but be prepared for the 1/2" outlet, flow (also effective pressure) will be drastically reduced going into the 3/4" pipe. Besides dealing with a lower flow, The first bathroom (10 feet away) worked preaty darn well! About 104 degrees. The kitchen (20 feet away) was adequate at about 99 degrees, the final bathroom (35 feet away) was a dismal disappointment at 92 degrees. In winter subtract 5 degrees across the board. This is set for max temp and max flow valves. Running 2 in parallel would be required for normal houshold pressure. Local individual inline units are better if there is distance involved. **Q: Does it use 1.5v d batteries? or does it need to be higher voltage because it is not turning on** A: Make sure your batteries are seated in the correct order. Make sure that the power switch on the bottom of the unit in in the on position. Unfortunately, when I did that it still didn't work until I opened up and found it was improperly wired. Hopefully you don't get that far down the check list. I would be more concerned about the seller. The unit works fine now. The seller, not so much. I would buy elsewhere. They offered me a refund, only if I removed the negative rating the product deserved it the state in which it was originally purchased. Good luck. **Q: New batterie and no hot water, no display showing?** A: Probably broken wire someplace. Power is not getting through. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as well as any other camp heater, and the price is good. *by C***S on September 3, 2025* My old CampLux heater I had been using for about six summers died this year, realized just before a camping trip.

Everything works as it should and once the tank is, turned on ignite, but doesn’t stay lit shut back off. What could be my problem to fix this? This was my second time buying what second different brand I am purchased with this type of equipment. The first one lasted for a year or so, but this one here only lasted for four months. What could be the problem so please share me some tips ### ⭐⭐⭐⭐⭐ Money very well spent. Works like a charm 😁 *by R***N on March 13, 2025* I'm currently homeless well actively camping lol. I bought this because you gotta shower and cold baths during the winter are terrible. Set up was a breeze and after installing the batteries required it fired right up. I don't have a source of pressurized water so l'm using another amazing purchase from Amazon the rechargeable camping shower kit the pump has more than enough pressure to satisfy the hot water heater. Couple fitting from Lowe's I was in business. The size is perfect for tent living and it's seems very well made but for $125 and the ability to have hot water and it can get very hot if you crank up the gas and lower the water flow I'd buy it again if it lasts a few months. All mounting hardware and even gas line Teflon tape are included. I've had no issues with leaking water or gas as of yet. I'm thoroughly impressed with the bang for the buck. Other camping hot water heaters are 3 or 4 times more. Also love it shuts off when you turn off the water to conserve and fires right back up soon as the water is flowing again ## Frequently Bought Together - Portable Water Heater Propane Tankless - 6L 1.58GPM RV on demand Hot Gas Outdoor Digital Display Water Heater for Camping,Boat,Cabins - SHURFLO (255-313) 1/2" Twist-On Pipe Strainer - SEAFLO 33 Series DC Diaphragm Pump – 4-Year Warranty! 12V, 3.0 GPM, 45 PSI, Self-Priming, Run Dry Safe, Built-In Pressure Switch | Ideal for Marine, RV, and Water Systems --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/456556688-portable-water-heater-propane-tankless-6l-1-58gpm-rv-on](https://www.desertcart.jp/products/456556688-portable-water-heater-propane-tankless-6l-1-58gpm-rv-on) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-02*
