Want reliable, fast hot water upta camp? Worried about pilot lights blowing out, or some bug getting in and roasting itself? Have limited space but big dreams? If so, this is the heater for you! Seriously, this thing was a breeze to mount and install. Water in, water out, and connecting the heater to the propane system was simple. It tucks right into an alcove on the outside wall. Now we have hot water for showers... a game changer! And boy does it get hot, if you want to. Temperature options range from tepid to thermonuclear, and you can control the output right down to the degree. If you want hot water fast, buy this thing. It's well worth the price. It's given me a summer of hot water so far, and I expect many years to come. Buy a pair of D batteries now and then, and it should last for years. I include photos of the front, fittings, and vent because the stock images are a little lacking.

This little heater is awesome! Super easy to set up — I had it running in no time. The water gets hot fast and stays hot, which is perfect for camping or outdoor showers. I was honestly surprised by how powerful it is for the size. I’ve used it for camping trips, rinsing off after working outside, and even hooked it up for an outdoor sink. Works great every single time and doesn’t burn through propane like I expected. If you want something reliable and portable for hot water on the go, this is it.

Works great. Had unit over a year with no issues. Used about 300 days a year. Very good temperature control. Even with temperatures in the low 40’s. Unit installed in an outside shower. Eco mode sips fuel in the summer.

Doesn’t hold up with time Had it a little over a year and it’s bombed out. There’s too much electronics in it for a hot and humid outdoor environment ( Florida). For the price point I expected it to last longer than this. We had it plugged in as a shower next to the pool. It worked well while it worked but it’s simply not durable enough. We ended up getting a new starter kit for it and installed and it didn’t work either. Now it’s trash or disassemble it and find a way to manually start it and bypass all the electronics.

Located in Mesa Arizona. Product seems good on initial quality. I give it four and a half stars on the second day. My name is Lee. I'm a plumber buy trade. I just bought this Forest river 2010 travel trailer and the furnace and water heater failed the first week. So i disconnected the old 6 gallon tank heater that sprung a leak. I purchased this 2.62 gallon per minute unit based only on its rating and plenty of videos on you tube to check it out before purchase. it took a lot of labor the remove the old system and re pipe it for the outside use with this tankless heater. Unit functions / works well. its a little touchy to get the proper gas flow and water flow to the correct setting. Be sure to be careful the unit will produce extremely hot water140 degrees and more. the conditions i installed the unit is 70 pounds of water pressure which is very high. Due to high water pressure when you increase water flow towards high setting it would turn the unit off. You would have to reduce water flow and it would turn back on. If you had lower water pressure this would most likely not happen. The original travel trailer propane system was used to supply propane. I had to buy a 3/8" flare hose to connect to the trailer propane system. A separate bottle would have worked just fine. I wanted it to be a part of the original system of the trailer. Shower head was very good I replaced the shower head in my shower with it. To the plumbing aspect. I have pex 1/2" piping and cut out all the piping and valves for the old heater. I piped both hot and cold water with a hose bib / silcock which has mounting a flange and mounted them through the wall of my trailer. I purchased standard washer and dryer flex hoses for water connections and the 3/8" flare hose so it was a permanent installation but easy to disconnect and remove for travel or replacement. Unit mounted easy. I did have to install wood under the unit to make wall stronger. My travel trailer wall was just a thin piece of metal. One factor of note is that if you are trying to use two fixtures like the bathroom and kitchen sink at one time the unit cant really keep up with the higher demand for water. So temperature and water flow are reduced, but that's no big deal. In the end I like the unit... In Mesa Arizona we don't see freezing much so when its in the 30's cold and windy unit functions without issues. A noteworthy fact, there is no pilot flame its electronic ignition. I like 120 degree water. Unit takes 13 seconds to produce hot water at my kitchen sink in very cold conditions (30's - 40's). My sink is about 15-16' away. Its only 4 or 5 seconds for my bathroom which shares the wall the unit is installed on. one thing that that made me second guess the unit was the digital display. After I put the batteries in the display did not come on. I thought it was broken. The display will not be on until the heater is active and producing hot water. All in All the unit produces very, very hot water. Its propane efficient, again no pilot flame its electronic ignition. Unit is very quiet during combustion in comparison to other tankless heaters. Tankless heaters are the future of water heating. So as a comparison of the 6 gallon original heater and the Camplux heater, it's a no brainer. The original heater had a pilot and ran all day long to maintain the 6 gallons of water. The 6 gallons of water lasted 4 to 5 minutes when taking a shower. that's horrible and way to short. the original unit was really heavy, this unit is half the weight and much easier to work on. the old heater was a pain to work on being on the inside of the trailer. So, if your old system has failed just say good buy to it and put a modern tankless replacement for it and never run out of hot water. I got the unit and the needed materials for around 400.00 dollars. I did the labor so that's not factored in. the replacement for the 6 gallon heater was north of 600.00 buy itself. UPDATE: After using the heater for a few days, it had issues in my shower. when tempering the hot water with cold water in the shower somehow the unit turns off and stops producing hot water, but what i have realized is that the shower head that came with the unit greatly reduces water flow. so, I took of the shower head that came with the unit and replaced it with the one that was in my shower previous to my purchase of the tankless heater. this head dose not force the water through lots of small holes, so it doesn't affect the flow rate at the unit, thus it works properly. The unit is working well. You need to change the gas flow and water mixture when the outside temp changes but that's no big deal. Best of luck to you. Lee.

Only used for a weekend. Very nice for camping- game changer for roughing it. Shower head and line a bit short and shower head a bit flimsy and occasionally leaks but that might can be changed out later. Water heats super fast and can use lower settings. I would buy again. We have 2.64GPM.

I purchased this unit for an outdoor shower setup as I'm currently living in an older RV and the shower is very cramped. I'm 6'3" and barely fit in it. This thing has been fantastic for four months. It has great water flow and I love that you can see the real time temp on the display. After a brief snowfall and a couple of days of freezing temperatures, I noticed that the plastic shower head had a significant crack and the internal burner flames were bright yellow instead of the bright blue flame I was used too. There was an issue with the propane regulator and a couple of error codes displayed. I contacted Camplux technical support and they attempted to walk me through a fix for the unit. Even though with their help it became functional, it still was not working properly. They offered a new replacement unit without any hesitation and it shipped to me within a week of contacting them. Thank you Camplux for standing behind your products.
