I bought the Fogatti On-Demand water heater for my 2020 Ford Transit 250 Van conversion. It was easy to install and worked flawless well for the first year and a half until I neglected to winterize properly. My inefficiency in winterizing allowed one of the small copper water pipes to freeze and have a small blowout which I will have to repair. I called Fogatti customer support and they were extremely understanding and helpful. I will be receiving the parts I need soon and be able to get my van back on the road with plenty of hot water. Thank you Fogatti for making great products and having excellent customer support.

Straightforward and easy to install. It took me about 2.5 hours to remove the old one and install this one. Most of the time was spent removing the old one and modifying the opening. This is 1/2 inch bigger both sides than the opening in a Shadow Cruiser with a Suburban 6 gallon. To get the Suburban out, I had to remove the circuit board sticky taped to the top of it and pulling it out of the opening busted off half of the styrofoam insulation. Plus, the Suburban has wires running everywhere, I had to find the straight 12V pos and neutral (red and green, I just abandoned the blue wire.) I turned the 110V circuit into a wall outlet. The Fogatti is laid out perfect, the connections are easy to make. Unfortunately, I had to remove the screws holding the back panel (2 sides) just to get it through the opening, even after grinding off excess fiberglass and aluminum framing to make the opening bigger. I metal taped the sides of the back panel where the screws are removed, it is just as solid as having the screws in. Plenty of wire is included with the remote, unless you are mounting it in the bathroom, which I do not understand. I put mine by the power center and set it at 123 degrees and will probably never mess with again. A slight issue that I was already aware of; the heater takes a couple of seconds to turn cold water into hot water. When you close the kitchen faucet and then open it again, you have to wait to get hot water, maybe 7-10 seconds. I have to admit, it was nice with the tank heater having hot water uninterrupted within seconds. But, believe me, I can deal with it. First time I ran a hot shower without cutting off the water to soap up. No more Navy submarine BS. Luxuriated in that wonderful endless stream of water. Be sure to get a thermostatic mixing valve, I'm not sure what happens when this is starved of cold water (kitchen faucet opened while you are in the shower.) I bought this one https://www.amazon.com/gp/product/B09QPCMN7P/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 and it has been great (looks good too.) Plus, no more gas being used to keep water warm in the tank. And the outside cover of it looks a lot better, more subtle and stronger looking. And, a $120 discount from when I was pricing these during RV season. I'm a satisfied customer. Edit 12/17/23 - I got ten days of enjoyment from using this product. When I say enjoyment, unrestricted, full flowing hot water under all conditions. On the eleventh day, it started flaming out, right in the middle of a shower. Since then it has gone to 1) severely restricting the flow of water, 2) flaming out almost immediately, under any and all conditions. There is some stupid code built into the circuit board that will not let it simply heat the water. It is chasing ghosts. Going down the rabbit holes. During the ten days it worked perfectly, none of the ambient conditions have changed since then 1) propane pressure is the same or stronger (replaced with full tank, tried a heating blanket for the tank -failed.) 2) the water pressure hasn't changed (my faucets will rip out cold water.) 3) temperature of the incoming water (today it actually got warm outside, it was still the worst shower I ever had in my life.) I've tried every temperature set point, I've tried every faucet setting, I have a shower protocol now; turn it on full hot water set at 103 degrees, wait for it to flame out, usually 30 seconds. Stop the flow, restart the flow, wait for the next flame out. Usually 2 minutes. Stop the flow, restart the flow, enter shower, before it was giving me uninterrupted flow but not today. It kept flaming out. I contacted the seller of the item, they blew me off (contact Amazon with warranty issues, check the wires on the gas valve.) Hey, that's great, thanks for your concerns, it's not a big deal not being able to take a lukewarm shower. Thanks for all your help. But, check it out, this thing is coming back to you, and I don't want another one. You don't care and neither do I.

I have an on demand heater in my 5th wheel, and when I was prepping a travel trailer for my father in law I decided to swap out the original 6 gal hot water heater for an on demand unit. The RecPro had good reviews so I decided to give it a try. This one is actually way better than the unit that was installed in my 5th wheel and it's only half the price. It was easy to swap out the propane line, just unscrew it from the old hot water heater and bend the tubing a bit to get it to it's new location and screw it onto the new hot water heater. I did have to modify my PEX water hoses a bit since I was using twist lock connectors and the old lines had a bypass valve and many crimp connectors so I did not have enough hose to effective seal the twist lock connectors. The remote is good sized and easy to read and set. One thing to note that is also true of my 5th wheels hot water heater is that under low water pressure conditions it has trouble maintaining the correct temp, and sometimes it can jump up about 10-15 degrees above the set point. It's not a fault of the unit, but it is handy to know if you camp in places where the water pressure is less than ideal.
