Style: LP, 2.64 GPM
There are several brands of portable hot water showers available with different water flow ratings. The smallest camping type hot water shower unit from Camplux with a 5L flow rating will provide an ample flow of water for a shower or for washing the dishes when out camping. They can also be convenient for use around the home for a warm rinse after a swim in the pool, or for washing pets or washing down outside areas. They are designed to be purely portable, and so they can be quickly connected and transported on a two wheel dolly for immediate use anywhere hot water may be needed. This 10L hot water unit is somewhat dual purpose since it can be used as a portable under certain conditions but is more intended to be mounted as a permanent hot water unit with a professional installation. A propane regulator and hose connection is not included for this unit since the plumbing will be stationary. The piping will be more complex for permanent installations but when connected correctly will allow this little unit to behave with the same fury as a 150 gallon central water heater, all at a fraction of the cost. Just be sure there is an adjustment valve situated within reach so each individual using it is able to fine tune the temperature of the water to perfection. Otherwise, expect to be showered with a never ending flurry of complaints and gripes that your stupid shower doesn't work right. Not my favorite impression to be standing there wet and freezing and no hot water. Understanding the basic principles about what is required for these units to work properly will help achieve successful results. Operation is rather simple so many won't even take the time to understand fully just exactly what happens or what is needed when attempting to set up a hot water shower. 1. These units only have one water inlet for cold water and only one water outlet for hot water. There is a connection for a propane gas supply. When you connect gas and plug in the electric power (other units use 2 12V batteries), it will begin heating the water when it senses the water flowing through the unit. Thus, if either the gas or power is not turned on, the flowing water from the outlet will not be heated. 2. The heated water is relevant to the temperature of the water flowing into the unit. Very cold water flowing in will be heated sufficiently, but if the water flowing into the unit is already warm, then chances are that the heated water will be so extremely hot it may scald someone when attempting to use it if there is no means to mix cold water with the hot water. If the water flowing in is warm enough for a shower, then just leave the power off. 3. Gas fired hot water shower units mounted indoors must be vented to the outside. Understanding these three principles is necessary before attempting to plumb a tankless hot water shower that works well for everyone using it. By the way, Camplux no longer states on the Amazon page that there is an automatic 10 minute shutdown timer safety that cannot be disabled. Apparently people were getting freaked out at the thought of their showers shutting down before they were finished. At least I couldn't spot any such statement the last time I looked for it. There are some recent comments about it now being 20 minutes. I tried to contact their support for clarification about that by email and got back a message that said Amazon was at fault and they wanted to know the number of the part I needed, which clearly indicates how well they have perfected understanding English. If I didn't already have good results with my Camplux shower I think after that reply I would have just looked at another brand. In any case, after a year of using the unit, it continues to perform perfectly and the safety has never caused a shut down while I was using it. If it ever does, just flipping the power switch off and back on again resets the unit and the blessed hot water shall be wondrously replenished. The basic camping units simply provide one hot water outlet and need to be mounted in an outside area with good ventilation. With such a basic principal behind using a portable hot water shower, one has to wonder how things can go so terribly wrong for others when attempting to use your perfectly operating little shower. Well they do, especially when not really savvy about the principles that allow these showers to operate. Shower units like these are sometimes used as seasonal installations in hunters cabins out in the woods where some, but not all utilities exist. Having a little gas operated water heating device is a really nice convenience, provided there is a means of flowing water and electric power to run it. If not, then Camplux has a pump that operates on 12 volts or there are many others available that can also be powered from a portable generator and will provide adequate water flow from a tank of water. There are a vast number of simple to complex portable shower units specifically designed for this purpose available as well, so it is best to check some of them out as to which unit best serves your needs. My backup shower runs on 12 volts and pumps water from a bucket with about the same force as my Camplux. So simple. Regardless of the requirements needed to get the shower operable, the temperature of the water flowing out will always be influenced by the temperature of the water flowing into it. That may explain why there are suddenly complaints that the water is too cold as summer temps begin to subside. Although most water supplies have a consistent temperature year round, there are some cases when it will vary according to environmental temperature, and even depending on what time it is on a nice sunny day, especially when using a garden hose to supply a purely portable unit. Remember that more water flow tends to have a cooling effect even though the amount of heat remains constant. In a one outlet system then, the flow of water that may be too hot can be reduced in heat simply by increasing the flow of water without ever reducing the flow of gas. Placing an adjustable valve at the shower head will allow for variable water flow, and it works wonderfully. So if none of this makes any sense to you, then better have a professional install your shower with all the bells and whistles according to local codes.

I live off grid and previously had a tankless water heater that sprung a leak. I expected this one to be easy to install. The product specs listed 1/2” water connects. If you are plumbed with 1/2” pex, you will need a 3/4” to 1/2” reducer. I had to make a 30 mile round trip back into town for these fittings. Once installed it runs beautifully with great constant water temps. Another note, if you are using a pump of any sort, the heater does need a constant pressure feeding it or it will shut off and water temps will fluctuate in the shower. Off grid is a little trickier than municipal water. The fan and baffles in the exhaust area are great features as well. Very happy so far with the performance of this water heater.

Have been using this water heater for a few weeks now and absolutely LOVE it. We have used several battery started LP on demand heaters by eco temp and MArey, and finally moved to this electric started one. It is so incredibly superior that I can't believe I waited this long to try it! It not only heats water to whatever temp you want at the push of a button that is super user friendly; but it also mitigates the uneven water pressure that comes off of my well and gives great pressure with maximum control. Highly recommend! Can't believe the price, as it is sturdy and well made, well shipped...love it!

This is absolutely trash. I have had three of these now and they have all failed. At first they will appear to work quite well heating up water to around 150-160 degrees. Then after a few weeks it will barely break 100. A week later it will struggle to heat to 80. Also, the advertised protections against freezing ect are all blatant lies. These will absolutely freeze and break even when properly drained.

These things are very good for most part. Easy to install and when they work, they, they work great. There can be some issues. I've owned two, the 4.6 gpm and the 2.6 gpm. I use is for an outdoor shower and tub coming off a 60 psi well system which was originally a gravity fed system, so I've used them both ways . The biggest problem is the sensors they use. The manual says that you can have as low as 3.6 psi and still function. That's just wishful thinking on their part. I've got a calibrated pressure gauge on my system leading to my shower, and anything below 20 psi will cause issues. Mainly, the sensor not registering enough water flow to turn on the Camplux, even though water is flowing. If you've got city or well water, you're probably good. If you're off-grid and using gravity, your psi better be above 20. The other thing that is tricky is the propane regulator. They include one in with the heater, however, my first one was defective, and you might spend some time finding one that is synced with the heater. Some of the off the shelf ones used for grill will not work due to the gas sensor in heater being somewhat finicky. So if the propane tank is full and valve open, and the heater sounds like it's trying to light, but still nothing, It's probably the regulator. Adjusting the gas will not help, because that's just for the flame height once it's lit. Like I said, when it works, it's great, but it might take some tweaking on your part.

For what this thing is for, and the price, I have to give this 5 stars. I built a tiny house 5 years ago, for just me. I didn't have a lot of money at the time and needed an innexpencive solution to get hot water. I purchased this water heater and put it to work. It has been running strong ever since and it's used daily for everything, dishes, laundry, showers etc... Obviously at a maximum 2.64 gym, it's not going to replace a legitimate tankless water heater. I had to turn the water flow way down to adequate temperatures. Also watwr tenperatures in the shower can fluctuate pretty bad sometimes, BUT I do not hold this against the water heater as it's installed in an application it's not necessarily designed for.
