  • Worked right out of the box.
Style: 1.58 GPM/6L
I replaced a similar unit that lasted 10 years. I hope this new unit lasts as long. The set-up was easy and I have used it a few times now. It doesn't have an on-off switch like my old unit, but I always turn off the propane tank, so there is no way it could start up if the water was turned on accidentally. It has two simple control knobs. One controls the size of the flame and one controls the water flow. You can control the temperature of the water with either knob. The higher the water flow, the cooler the water will be and obviously, the higher you turn up the flame the warmer the water will be. ... show more

  • Works good at higher altitudes
Style: 1.58 GPM/6L
Purchased this unit for taking showers while out on hunting trips. Our camp altitude is 4100 feet and it worked perfectly using a 20# propane tank with no issues at all. I used a SeaFlow water pump hooked to vehicle battery and a 55 gallon plastic drum we filled at a spring for water supply. Temperature was easy to control with flow rate and temp controls. Water temperature plays a huge role in maximum heat output. On the last shower of the trip there was ice in the water drum and i was still able to take a nice hot shower by turning up the temperature and turning the water flow down. All the components supplied with the unit worked flawless but i did take a spare showerhead and hose just in case based off other reviews. Overall very impressed with this unit. Note: If your in freezing temperatures make sure to drain the unit after use to prevent damage and or bursting of the internal components. ... show more

  • Very good water heater - a bit hard to store away when not in use
Style: 1.58 GPM/6L
We've used the Camp Chef Triton 5L heater for years, loved it (until I let it freeze). They're no longer made, so I needed an alternate water heater for our off-grid property. This Gasland unit is a good replacement. It's not too hard to set up (see caveat below), and it works -- we've only used it for a few days, but so far, so good. HOWEVER...there is one "feature" which I do not appreciate. It's a bit hard to describe, so please bear with me -- the problem is a brass fitting which is used to connect your hose to the water inlet. In the Triton heater, this fitting was made up of two components one of which attached to the hose, the other to the heater's water inlet - one piece rotated freely within the other. After attaching the smaller piece to the heater, you inserted a rubber washer into the other piece, and could then TURN THE LARGER PIECE TO CONNECT THE HOSE WITHOUT TURNING THE SMALLER PIECE. Simple concept, right? Unfortunately, Gasland somehow failed to grasp the perfection of this concept. Their fitting is a SINGLE brass connector with threads at each end. No matter how you try to attach the hose, you're SCREWED (pun intended). If you attach the fitting to the heater, you can't then turn it to attach it to the hose without unscrewing it from the heater. If you attach it to the hose, you can't then turn it to attach it to the heater without unscrewing it from the hose. CATCH 22! So how did I resolve the issue? First I disconnected the gas and water outlet (spray head) I then attached the #%@& fitting tightly to the hose. I then twisted the whole hose about one full rotation to allow me to start the fitting onto the water heater, for one thread. THEN I TURNED THE ENTIRE WATER HEATER AROUND AND AROUND AND AROUND to screw it onto the fitting until it was almost tight, and used wrenches for the last quarter turn. It left the hose slightly twisted, but it's working. The only other VERY SMALL negative -- when not in use, we can't leave any water heater unprotected outside where we use it, we don't want to subject it to rain and dust and pollen. It needs to be covered. I built a "dog-house" from plywood, which fitted nicely over the propane tank and our old Triton heater, which stood on legs on the ground. Unfortunately, although it's easy to pull the Gasland heater off the bolt from which it hangs, you can't just set it on the ground, as it has no legs -- the water and gas hoses get in the way. It has to be laid on its side, where it takes up to much acreage to fit in my dog-house. #&*@!$$! Oh, well. [sigh] I'll build a better dog-house. All in all, this is a VERY good water heater...so far. Stay tuned, film at 11. ... show more

  • Do yourself a favor and don't by this crap
Style: 1.58 GPM/6L
First off let me start with Gasland is actually Camplux. I purchased our water heater last September 2021 and it stayed in the box in our storage until this past weekend 2/19/2022. I took it out of the box and needless to say once hooked up it failed to ignite and make hot water. I had it connected to a 50psi rv pump with a 5 ft hose (per Camplux requirement), new batteries and a full propane tank and still no hot water. I contacted Amazon to start the process of warranty since the retun window had closed. Now on to Camplux support...What a joke. They wanted a video of the unit connected (failure as they only allow 10mb limit), got it down to 6mb and again (failure, wrong format mp4 is not acceptable). Had to call support and guy had me run through everything I had already done including taking th front cover off to try and get it to ignite manually (again failure) I noticed that there was a lot of oxidation on the internal components and was asked to submit a picture along with the order details, which I did. Now starts the BS with support. I start a lengthy email chain with them asking one question after anoth of everything I did before and after talking with their (Camplux) support guy. They reLly are expecting me to just let them replace the internal stuff instead of just replacing what is clearly evident the unit was used. Do your self a favor and don't by this POS with the name Gasland or Camplux. Buy something frpm a reputable company. ... show more

  • Really surprised how well this works
Style: 1.58 GPM/6L
I have used this about a dozen times so far for Van Camping and I am really surprised how well this works. I have it hooked up to a water pump and a 5 gallon tank It heats the water instantly so there is no wasted water and it will consistently and continually heat the full 5 gallons of water as pumps thru this unit. I like the shut off switch on the shower head as well so you don't waste water while you are lathering up. For the price , It is an awesome product and is working perfectly for me. ... show more
