Review: The best on-demand water heater for the money! - I purchased and I nstalled the Shower 8 Plus 55,000 BTU and it fired right up immediately and I had hot water within seconds. It’s a self contained unit that includes the high pressure relief valve. The only external part’s considerations you will need to make are the 1/2”” water inlet and outlets and the 5/8” male gas fitting that is on the back of the unit. My advice is to buy two flexible 1/2” faucet lines that include the 1/4 turn shut off valves on one end and 1/2” shark bite connection on the other end. Simply cut your existing 1/2” PEX lines in the appropriate locations and slip the two new flexible lines on and tight by hand the other end onto the inlet and outlet of the water heater. The shutoff valves will allow you to be able to shut off both water lines in case you need to service and flush the unit without having to shut off water to your entire RV. The electrical is self explanatory and uses a 12V positive and a negative/ground. The included digital controller uses two small wires that connect to the two blue wires on the back of the unit and it doesn’t matter which way you terminate the blue wires to the controller. Make sure you clean the outside mating surfaces before attaching the twelve screws on the outside of your RV and use new butyl tape and/or a good marine sealant to prevent leaks. Inside where your water heater sits screw down a couple pieces of wood snug on each side of the unit to help keep it stable so it won’t tend to shift when your RV is going down the road. That will prevent stress on the outside mating surface during transports. Overall I’m super satisfied with this water heater. I run the temp at 109 degrees and it’s perfect. It runs very quiet. You will have hot water when the electricity is out or if boondocking. Propane is cheaper than electricity and this unit is more efficient than older units and tank water heaters. It’s definitely worth the investment if you are on the fence just know that it’s a high quality product that is well put together with quality parts and materials. Fogatti customer service is better than other companies so that’s another reason to buy from this company. I threw my 100% working Suburban tank water heater straight in the trash bin and didn’t look back. I didn’t shed one tear and I threw it like an angry gorilla! I can now have continuous hot water!
Review: Fantastic RV tankless water heater - Works better than described and easy installation to boot

## Features

- 【Unprecedented experience】The high altitude suitability mode allows the machine to run smoothly even when driving the caravan to the high Denver plateau at 9,800 feet. Staged combustion technology, which controls the amount of flame in summer, prevents the water from getting too hot and saves the limited propane gas available for caravan travel.
- 【All RV water heaters can be replaced】The Fogatti RV water heater have a wide range of applications. The opening is 13 x 13 inches and the door is 15 x 15 inches. It can replace Suburban and Atwood's 6 gallons tank water heaters, as well as Girard and Furrion's tankless water heaters. If you previously used a 10 gallons tank water heater, it would need to be retrofitted with an 18 x 18 inches door.
- 【Incessant hot water】With 55,000 BTU of power, it can produce a maximum of 2.9 GPM of hot water. Some tank heaters can only store up to 6-10 gallons of hot water and run out of hot water in 5-8 minutes, whereas our hot water supply lasts over 40 minutes.
- 【No waiting】RV tankless water heaters are taking off. Tankless water heaters are better than tanked water heaters for continuous showering of multiple people. There is no need to waste 20-30 minutes waiting for hot water in the middle of the shower, so you can enjoy hot water at all times. It uses propane for heating, so there is no need to worry about running out of power in your caravan.
- 【Save money and trouble】Fogatti has always thought of you, with a pressure relief valve built into the product, so you don't have to buy and install it separately. And it also comes with a 15 x 15 inches door and an intelligent remote controller up to 2 meters long.
- 【Safety and reliability】The product is CSA certified and has multiple protection features such as a built-in forced exhaust fan on top, stable combustion, automatic gas shut-off for accidental flame failure and anti-freeze.

## Questions & Answers

**Q: There's a little water coming out from the pipes after unboxing, is this a brand new one?**
A: Mine does that too and it had some corrosion on the back I got it installed and it says a faulty error code 4 saying inlet temperature probe is faulty or the inlet temperature probe is open or shorted. Please check or change the outlet. Temperature probe connection.

**Q: They stated that remote works up to 2 meters away. Is not enough for my aplication . Remote will not work if wires from remote are extended ???**
A: I didn't see the 2 meter limit when I got mine. My application did not require additional wire. Over the length of wire a, keep in mind the power drop off over distance. The wires are very small, like 30ga. maybe a bit larger than that. This means low amp application at 12v. The remote has maybe a meter of wire attached and I could see the power requirements fall off.

**Q: Where does my brown wire coming from my monitor connect too?**
A: I don't remember a brown wire.  Just leave it free and see if the unit  works.

**Q: What psi propane regulator is needed?**
A: Well this is designed to operate off of the low pressure 2nd stage regulator on an RV, so 11" water column or about 1/2 psi.

### ⭐⭐⭐⭐⭐ Fantastic RV tankless water heater
*by S***C on December 7, 2025*

Works better than described and easy installation to boot

### ⭐⭐⭐⭐⭐ Off-grid hot water solution
*by S***N on September 13, 2022*

Using for an off-grid cabin. Follow other reviews' instructions on installing pressure relief valve. Took me a while to figure out all the parts I needed to make it work for a cabin rather than an RV. Lots of trips back and forth from the hardware store, but alas, it works and water is HOT!!! Wife and I use it for showers and washing dishes. Hooks up to a standard grill tank. NOTE: Use a 100 psi pressure relief valve. NOT the standard 150 PSI valve you commonly find at Lowes or Home Depot. Fogatti sells the right one on Amazon. 12/2022 UPDATE: So, most of the US just went through the deep freeze. During this time, water inside the heater froze causing a part to rupture and water was spraying like crazy inside the unit. I called Fogatti and spoke to an actual person on US soil without a foreign accent. I'd add an extra star for this if i could. I explained the issue and texted them an image of the part that broke and they immediately shipped me out a replacement part! If I were to knock off a start for the part breaking, I'd have to add ot back just because of the customer service. So I still remain at 5 stars for this product. It's actually 6 stars because I spoke to an actual American. 1/2023 UPDATE: Shipping was slow. Very slow. But the part was very easy to replace. While i was waiting for the part to come in, it still made hot water even though it was leaking. Do I still give it a 5 star? Almost. I'd say a 4.9 star. 4/2023 Update: Not sure if I can recommend this anymore. A few days ago the water heater stopped turning on. I connected a multimeter to the 12V batter and am ready 12V. Tested the wires that go from the battery to the unit' still getting 12V. Tested the wires coming from the unit, going into the remote - 0V. Spoke with customer service and they were very pleasant to work with. Again, it was personnright here in the US and not some foreign call center that you can't understand. So anyways, I spoke with the support tech and he asked me to check a few more things and he determined it may be the board that has gone bad. They're shipping me a new one, and while I do appreciate the good customer service, this thing isn't even a year old and it already needs new parts. I do have a 5 year warranty, so I'll he able to get parts for the next 5 years, but after that, if this thing still keeps breaking, I'm going to have to look for a different unit. If Fogatti's units were as superb as their customer service, this would be a 5/5 stars all day. Dropping to a 3 star. It would be a 1 star as far as reliability, but their customer service is so good it brings them up to a 3. If I get these new parts and I don't have any problems anymore, it'll go back to 5 stars if it stays problem free. 6/2023 Update: Git the parts, installed and it wasnt working still. Spoke with Fogatti again. We used the multimeter to see the voltage going into the unit: 11.67V. Apparently this was way to low and it won't turn on. My led lights turned on, but not my water heater. I rewired a few things and got it plugged into my solar power station, sure enough, it's turned on with hot water. It wasn't them after all. I need to calll the technician again so I can confirm he was right. 5 stars again. What a rollercoaster lol 2/2024 UPDATE Since I rewired the water heater to plug directly into the AC solar inverter, I have not had any issues with the unit turning on. Now, if you're using hot water, and suddenly it goes cold and the little black control box starts beeping, turn off the faucet/shower, wait a few seconds, and turn it back on. If it still keeps happening, turn off the faucet/shower, and turn the hot water 3/4 of the way, let it get hot, then turn on all the way. Not sure why I need to do that, but it seems to work. 11/2024 Update: Still no problems since the last update. Wiring this thing to be able to plug directly into a standard wall outlet was the ticket. Significantly less issues with water suddenly going cold. Still happens though, but the trick I used in my previous update still works. Heading into winter now so we'll see if the pipe freezes and explodes again. 3/2025 Update: Coming out of winter. Pipes did not freeze. FYI, this unit can supply 3 fixtures with a bit of decreased performance. Built an addition to our cabin, will need to upgrade to a larger unit or get a second unit.
