Color: 3.18GPM 82,000 BTU White
Style: Liquid Propane 3.18 GPM
I've used this water heater every day for a year and a half and it still works great. It was easy to install. During the winter I have to turn the temperature up on it just a little. During the summer I turn it back down. T

I got one of these 3.18gpm automatic heaters from a warehouse deal. A white one if that makes any difference. It is in Fahrenheit rather than the Celsius that would be expected from prior reviews. Not sure of the other changes, but I can also say that the blower fan is at the top of the unit just under the flap valves. I believe the combustion blower was at the bottom on the earlier units. I've yet to see if it has low temperature protection in this model, but I doubt it. I will be adding a thermal switch inside that starts up the blower fan whenever the internal temp drops below 40. It should run here and there drawing warm inside air through the device occasionally all winter. I've only hooked it up to test it then put it away so far. I am not at the stage with my tiny house to install it yet, but I couldn't pass up the warehouse deal and bought it the moment I spotted it since this was the unit I was going to use anyway. In my initial testing, the only thing I would consider a flaw is that you need quite a flow to make it start up. I would like if it started at more like 0.3GPM rather than almost 0.7. That's a lot of water for me. I use 0.5 GPM on every fixture, even the shower even though I have unlimited well water. The blower makes a bit of noise, and there is an audible clink as the flaps shut when the blower powers off. No big deal, not as loud as a typical bathroom vent fan. For me this will partly double as the bathroom vent on my wall. Something to pay attention to is that most houses are in a negative pressure during the winter. Especially down low in a basement. Those who use this in the winter and have it freeze may be experiencing cold air being constantly drawn into the unit past the flaps because their house is leaking warm air above. Something like a chimney wastes a TON of hot air which has to come from somewhere. I was able to turn the flow rate up very high before it couldn't hold 120*F anymore, at least to me given how little water I am used to. For sure this thing will be able to give you at least a pleasant shower or one large warm water task at a time even with a feed temp of 33*f. The real limit will be getting it to actually start with the lower flows needed for that. I'm sure that it will do at least 1GPM even in those extremes though. Didn't do the BTU/hr calculation for the water volume and temperature. The 3.18GPM will assume a more reasonable feed temperature of course. Speaking of BTU this claims 80k BTU/hr. I don't know if that's the gas consumption rate, or the actual thermal output. Assuming it's thermal, the gas rate is probably more like 96k. This means that the heater will run maxed out for 1 hr per gallon of propane, or about 4 hours total on a 20lb tank that is full at absolute max flow rate. Ultimately this means that it should last quite a long time for a family taking average showers. LPG has 95,500BTU energy per gallon. This is also reaching the limits of a 20lb propane tank especially if it's cold. When propane gas is drawn from the tank the remaining liquid propane boils to replace the gas consumed. This lowers the temperature which then changes the pressure coefficient to be lower. Eventually it will get so cold it cannot boil enough to maintain pressure. This heater could freeze a 20lb tank like that at max flow. I will come back and update this when I eventually have it installed, then again when someday it fails as all things do. hopefully it remains a 5 star review either way. Final note, take a close look at the measurements. This thing is HUGE if you're used to the D battery ignited ones. It's small for what it is, don't get me wrong, but I was caught off guard by it slightly because I never even looked at the dimensions of it. Not negative at all. Just an observation. I assumed the output pipe was 2", so in my head the device was going to be some 30% smaller.

Updated Review: So I still stand by my original review of the first unit I received and the hard money I spent to install, uninstall, re-pipe, and ect so I will keep the original review included below, but things have changed drastically. Following my original review I was super surprised to see I had been reached out to by the company. They expressed concern and asked how they could make matters better. They suggested a full refund and sending me a brand new unit. I was very happy to proceed and my new unit arrived fast. The new unit arrived well packed, but the box was pretty destroyed in shipping. The unit itself was great and fired up perfectly on install. The new unit I received has been wonderful. Truly we on the off grid homestead have been very happy with this unit. The unit is simple to operate and has generated awesome quick heat. Propane use seems low and the unit is super quiet. While it does also use 120v, my watts meter seems to notice nothing of real use much of the time. Overall, I love this new unit. Now will it last IDK? I pray. Is there issues? A few. We notice when the unit has any kind of restricted water flow from the pump it tends to go a bit hot crazy. The heat will jump wildly until a consistent pressure is reached. This is mostly rare, but he have noticed it when the pipes are cold from our cistern. Overall I would by again in the future. The new unit is great and the customer service has been excellent. Original review: It’s a instant propane water heater, well that is if it arrives working. So I purchased this unit praying, no hoping, previous reviews of this unit were wrong. People had complained about it not working or failing. If your like me you love to give the underdog a chance. A chance to win the day, however my off grid hopes were dashed the moment I opened the box. The unit seemed well packaged and it was. Sadly the company sent me a defective unit with damage to the glass led screen and and non-working up button. I noticed the glass damage, but installed it anyways hoping the damage was mostly cosmetic. Sadly I was wrong. The unit jumps around with temps, pressure, and the power button is all that works. Very sad as it looks like it would be nice, like nice as an art piece…..if it also worked. So sorry to dash anyone’s dreams on the this unit, as I paid good money to install it in my off grid bath house and wanted it to work. If I was you, I would purchase somewhere else with someone else, or a least until this company or unit is corrected.

The CAMPLUX 3.18 GPM works exactly as desired. I have a small cabin with a kitchen sink, bathroom sink and shower. Hot water feels stable, ignition and heating is on demand. The unit has not been heavily used but is working as desired. You can NOT have mixing valves. Separate hot and cold valves are required for the system to function as designed. Installation was relatively simple. Proper venting and clearance to combustibles are the biggest safety issues. There is some gas firing noise when the unit is operating. In my opinion this is desirable and not a negative. I contemplated going to the next larger unit but running hot wide open both sinks did not affect the temperature.
