One year update.... The unit is still running like a champ! I'm getting a 73°F rise across the unit in the winter time with 40 something inler water temp. I can find no fault with this unit. Three month update... Still running strong AND using less propane than I would have otherwise with the 12 gallon suburban. As we all know, running dsi heaters with both propane and a.c. element create faster recovery. A non issue with the Girard unit. I am seeing a 65°F rise across the unit, but I have mine set at 115°F anyway. Still, by far, the best $500 I ever spent for our coach. I just wish I had put these in all if our rv's! Momma is still happy with her 25 minute showers and I don't mind the extra time under that hot water to loosen up these old bones before bedtime. I've seen some other reviews really ragging on this unit. Remember three things, you MUST provide a MINIMUM flow rate of 0.9 gpm as pulseless as possible or the flow sensor will not trip the control circuit. If, when adjusting your temperature at your plumbing fixture (shower/ sink) and the hot water side flow drops below 0.9 gpm, you will get hit with a slug of cold water. I prefer setting the temp at my desired water temp and running hot wide open. This prevents any undesired flow characteristics due to infamous low flow water fixtures associated with recreational vehicles. Finally, if you don't have shore connections, don't let your shower time get away from you or you'll have a full gray water tank before you know it. Remember, you'll also need to order a replacement door specific to the existing, EXISTING unit which you are replacing/retrofitting. This has been the absolute, best investment we have ever made towards improving our RV'ING experience! As a plumber, installation was fairly straightforward. Using existing 12vdc to my "old/new" 10 gallon Suburban in our new 2017 Columbus fifth wheel, the installation took about two hours. You will need to order a separate door for your existing opening/water heater make. If you are of average aptitude and mechanical skill, you should be able to do a self install. If you have any apprehension, whatsoever, have a pro install. Today, I took my first ever, 10 minute shower in my fifth wheel, as did my wife. The heater does have a minimum 0.9 gpm flow rate to fire. So, if you are using a pressure regulator for your shore connection, verify that you can get at least 1 gpm thru your shower head. I did the old bucket and stop watch trick and ended up at 1.5 gpm. I also used the existing 12vdc from my water heater switch on the control panel. You might see some complaints, but trust me, if you correctly install and provide proper water flow, you will LOVE THIS HEATER!

My wife and I are Full Time RV'rs. We roll in a 2016 Coachman Pursuit 32 ft Class A. Our hot water tank split and was totally trashed. After lots of research we opted to go tankless. Again, lots of research brought me to this unit. I have to tell you the install was very easy. If you have just basic skills and knowledge you can install this yourself. Make sure you have a roll of Butyl Tape and for us a small junction box. After removing the old unit, we installed a small junction box to connect the 12 volt power right off the furnace that sits next to the water heater. I also replaced both water line connections with new ones. I opted to use the steel mesh lines like the ones used on washer machines. Gas line connection was easy peasy. The only thing you don't get is the door cover. You can not use the old door cover because the exhaust system is completely different. The one that is recommended with this unit fit perfect. The gas usage is 100% more efficient than before. As you know throughout any 24 hour period the gas would light off and reheat the water in the tank as the temp dropped. And if you really needed to use it for say a shower, you need to shower fast. 6 Gallons does not last long. With tankless. The gas fires off ONLY when you open a hot water valve. After about 15 to 20 seconds you have wonderful hot water. This unit claims that it can run continuous for almost 2 hours. Have not tried it but our showers are now wonderful. The control panel is simple. It is preset at 115 degrees. you can change it up or down at your pleasure. We have found 115 is perfect for us. So far this has been a great unit and the replacement cost for my original unit, 6 gallons, gas fired.....was 811.00. So this purchase with the door, saved me 300,00. Its a great unit and we love it!!!!

The monitor allows for simple adjustment of the water temperature. It is a great feature. The monitor also has a red LED and a green LED. Nowhere in the instructions does it explain the meaning of the LED’s. Apparently, the red LED means that the unit is armed. I still don’t know what the green LED means but I can switch it off and on. It doesn’t seem to matter.I bought this to replace a 6-gal tank unit which froze and burst. When I opened the Girard's white control box cover to inspect the circuit board, I found that the blower wiring harness was pinched during assembly between the box housing and the box cover possibly damaging the wires: just another example of lousy workmanship, poor supervision, and lack of quality control. To be fair, I find poor workmanship and manufacturing defects everywhere I go. Winterization is a problem because there is no way to drain the unit without draining the water system and blowing air through it. Otherwise, you need to maintain LP gas and 12V DC power to the unit to protect itself, or antifreeze the whole water system. This is important because if you drive/pull your RV through freezing temperatures, the heat exchanger could freeze because it is exposed to the outside air through the door vent and your propane needs to be shut off when you are on the road. I don’t like that because the rest of my water system is insulated and my fresh water tank is electrically heated to prevent freezing so that I can camp in freezing weather with liquid water, even without propane, and I wouldn’t have to drain the whole water system (and blow air through it) every time I drive through the mountains or spend a cold night in the desert without propane on. How is one going to blow air through the heat exchanger when on the road? Hot water tanks, by comparison, are insulated and come with a drain plug. This on-demand unit needs a drain valve so I tapped my water line at the lowest point next to the Girard unit and installed my own drain just for the hot water circuit. I may have voided the warranty by doing this but the warranty does not cover damage due to freezing. See attached photos. UPDATE This water heater works great and has the best features. I found a defective pipe weld but I still think this product merits 4.625 stars. To be fair, I find defects in EVERYTHING! I sprung a leak in the water inlet pipe that the pressure relief valve is connected to. It happened when the temperature went down to 32°F for about an hour and I did not have 12Vdc power applied. The pipe that was damaged is only a $29-dollar part but a lot of work to replace. I highly recommend checking the pressure relief valve adjustment after installing the unit. This is not covered in the manual. It’s the thing that looks like a splined shaft in the bottom right. To adjust the pressure relief valve, turn the inside (core) of the relief valve with a flat screwdriver until water comes out with water pressure applied, then turn the core until the water stops. When I installed my unit, I also installed a drain valve in the lowest part of my hot water system so I would not have trouble winterizing in storage but I eventually discovered that I could have accomplished the same thing by removing the pressure relief valve assy by unscrewing it from the joint on the water inlet pipe. You can accomplish this by turning the splined shaft counterclockwise until it separates from the water inlet pipe. You will still need to blow some air through the system to get all of the water out. For all-season use, I think this is better than using an tank-type unit.

The item purchase is the exact unit I have on my RV. The install is very easy and straight forward. Just make sure you purge the propane tank when turning it on. Purge from the stove. Also, it came with the control unit which you don't have to replace unless your current one is giving problems. At the current time its work. I have no idea if it will go out or not, however I recommend to anyone looking to purchase this unit.

Installed 1 year now and I can’t wait till it breaks so I can replace it with hopefully something that works right. It works just enough to keep me from ripping it out of my RV and throwing it in the dumpster for the amount of money I paid for it. Here’s the problem, it can’t keep up with any sensible amount of water flow. I set it at 120F, I bought an expensive commercial grade water regulator after the cheap ones didn’t help. I’ve adjusted the built in regulator and it still can’t keep up. At first it could keep up with the kitchen sink, but never the shower. After 1 year of use it can’t even keep up with the kitchen sink now. I have to turn the hot flow on the shower so far down that hot water only trickles out for it to reach anything over 90 degrees. Turn the water flow a hair up and it will not heat anywhere near my 120 degree set point. Turn the water down to a trickle and I can walk it up to about 118 degrees but if I turn the water pressure down any lower its built in sensor doesn’t see the water flow and it shuts down completely. The water flow is such a balancing act that what tends to happen is when my hair and face are covered in shampoo it thinks there’s no water flow and it shuts down, instantly blasting you with freezing cold water. If I increase the hot water flow it can’t heat the water fast enough. It almost works like a dream, it just needs a few tweeks in its design to be perfect, but as it is its worthless and will anger even the most passive person trying to use it to take a hot shower. They just need to slightly increase the size or capacity of the heat exchanger portion so it can keep up with normal water flow and pressure. They also need to make the water flow sensor a little more sensitive to lower water flow so when you do have to turn it down lower to keep up it doesn’t just shut off. I can not believe they didn’t see these obvious problems with it during the testing phase prior to putting into production and on the market, they were so close to nailing it.

This tankless water heater got to us in good shape and was simple to install. Previous to purchasing this unit we purchased a Fogatti unit first mainly because of its dimensions (the vertical opening in our RV is only 12.5") as most of the others were too tall. Unfortunately I didn't think to check the size of the door it came with and when it got to us I could immediately tell the width of the door wouldn't cover our opening so we sent it back and kept looking. This Girard was stated in the Amazon ad as being the correct dimensions to fit our opening but we couldn't find a mention of a door/cover being included. What was confusing was that the main group of product photos included one that gave the unit dimensions as 12.5" X 12.5" X 13.75" (this was the only other unit we could find that fit our opening) but when you scroll down and look at the item description it gives the product dimensions as 14.5" X 17.8" X 14.6" (?!?) This seemed to possibly reference the dimensions of a door but we could find no mention of an included door plus our just previous experience with the Fogatti unit had a door included in a separate box inside the main box, so we assumed a door came with this one as well. It did not. To cut this short, we ordered the correct size door (there are two sizes) but once the door got to us the instructions mandate the unit be moved all the way to the right side for the door to fit the opening correctly and in our case a water fitting, that could not be moved, prevented the unit from being properly placed. Just to be clear, this is a quality water heater in every sense and to this point is operating flawlessly. This next part was pretty frustrating: Tweety's charged us $10 to ship the door to us, when we went to ship it back the cheapest price available was $25. We declined to pay that much as the door only cost $48. Tweety's did not opt to cover shipment back to them saying that shipping costs are rising(!) Bottom line is: make sure you perform due diligence to know as much as you can about what you are buying. Even then it's tough to get all the answers up front. Good luck

I bought this several months ago. It took me a while to be sure I had all the items I needed to install it. And have someone to help with lifting/holding it. After I installed it, I adjusted the temperature to something I thought would be great. In the end I set it back to the default, 115°F. It was shortly after installing it that I thought it might need to adjust itself to the water flow and pressure so that it would stabilize at the set temperature. But soon it was going crazy. It was getting so hot that it would error out and stop heating the water. So, I was back taking showers that ended in cold water. But one day, I was talking with the person who helped me install it. And I realized that the hose of my incoming water to my trailer was laying in the sun. And we have been having REALLY hot days, as many of you know. I tried a couple times to test this. I turned on the hot water and let it run. Again, it went ahead and errored (heat going to/above 140°F). I then, later, tried to just run the water, from the cold side. It got exceedingly hot to the touch. After both of those tests (remove the sun heated water in the hose) I let the water heater do it's job with the now unheated water. It kept the temperature perfectly. I do not know if this unit auto-adjusts to pressure/flow, but after finding out it can't cool super hot water (DUH!), I am finding this water heater to be THE BEST INVESTMENT I HAVE MADE IN THIS TRAILER! I recommend this unit to anyone who is thinking about replacing an older heater that has a tank. My use of LP Gas did go down a bit because it isn't keeping the tank of water heated (tankless). If playing with gas, water and electrical connections is not your thing, then seek someone to install it. I am in my 60s so I have repaired/replaced most things found in a home and was comfortable to do it myself. The instructions DO NOT RECOMMED THIS. So, bottom line, I really recommend this tankless water heater. If you are a do-it-yourselfer, get someone to help lift and steady. It is much lighter than what came out (and, yeah, I drained it first) but it is still better to have a hand. Now I am trying to figure out a way to shield my water hose from the sun. In a way that won't become a home to insects or vermin. If you buy this water heater, I believe you will enjoy longer hot showers and maybe even a longer time cleaning dishes and such under running water at the sink.
