Review: Buy it buy it buy it! - We are a family of 6 living in our camper full time traveling with the husband for work and our fifth wheel only had a 6 gallon heater and we finally talked ourselves into going tankless because it was a nightmare trying to bath everyone. We have absolutely zero regrets, install was super super easy start to finish took only about an hour. We only had one issue and that was water leaking out the relief valve in the front of the tank, which was resolved by turning the heater and propane on and allowing it to run for a minute and it resolved itself and hasnโ€™t poured water out since. For some reason the relief valve hadnt sealed properly, but like previously stated, we turned the heater on, propane on, and let the water run inside for a few minutes and it sealed off. The water gets hot enough for me, and I like my shower to feel like my skin is burning off. The tank does kick off after about 20 minutes which is only a slight minor inconvenience, which is easily resolved by shutting the water off for a minute and turning it back on. Takes about 10-12 seconds to get hot water, about the same as our old water heater, because obviously it has to run the hot water up through the lines, I donโ€™t see why people complain about this, itโ€™s not any different for us. However it takes about 15 seconds to get to our second bathroom and shower, which is still no different than our old heater. But we love it and love that we can now give back to back showers, definitely makes our fifth wheel feel more like a home. ## Features - ๐‡๐ข๐ ๐ก-๐€๐ฅ๐ญ๐ข๐ญ๐ฎ๐๐ž ๐‘๐ž๐š๐๐ฒ: ๐…๐ฅ๐š๐ฐ๐ฅ๐ž๐ฌ๐ฌ ๐‘๐• ๐‡๐จ๐ญ ๐–๐š๐ญ๐ž๐ซ ๐‡๐ž๐š๐ญ๐ž๐ซ ๐ญ๐จ ๐Ÿ—,๐Ÿ–๐ŸŽ๐ŸŽ ๐…๐ญ! 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 - ๐€๐ฅ๐ฅ ๐‘๐• ๐ฐ๐š๐ญ๐ž๐ซ ๐ก๐ž๐š๐ญ๐ž๐ซ๐ฌ ๐œ๐š๐ง ๐›๐ž ๐ซ๐ž๐ฉ๐ฅ๐š๐œ๐ž๐: The Fogatti RV water heater have a wide range of applications.

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 - ๐€๐ฅ๐ฅ-๐ˆ๐ง๐œ๐ฅ๐ฎ๐ฌ๐ข๐ฏ๐ž ๐‘๐• ๐–๐š๐ญ๐ž๐ซ ๐‡๐ž๐š๐ญ๐ž๐ซ: ๐๐ฎ๐ข๐ฅ๐ญ-๐ข๐ง ๐•๐š๐ฅ๐ฏ๐ž + ๐Ÿ๐Ÿ“" ๐ƒ๐จ๐จ๐ซ + ๐Ÿ๐ฆ ๐‘๐ž๐ฆ๐จ๐ญ๐ž!

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. ## Customer Reviews ### โญโญโญโญโญ Works great! *by D***L on August 2, 2026* The 13โ€ cover model fit perfectly.

I can run the trailer on 15amp, 30amp (if running space heater) or kicked down from 50amp. Making us camp sight compatible. ( power wise) And keep most of everything running at the house off the standard 15 amp outlet off the back porch. ( running ยฒร— fridges all L.E.D lighting, and a 12k BTU. mini split (dc inverter motor) for climate control. Surround sound, playstation and tv. Just cant run a space heater off the one 15 amp But this heater is a direct replacement for those with a tanked style water heater in RV or camper. I have been using this unit for over a year now and still working as the weekend I installed it. For those considering this unit I will say it from experience, it is beneficial to set the temperature you desire from the control panel if not it may be to hot to stand. With the flow rate we have never had an issue while running the shower (residential single handle with scaled guard maxed) in a 36" ร— 36" shower and the sink faucet (home kitchen faucet) at the time. Have used in even in the freezing Temps once on a trip. Our drain line from the gray water tank froze but the water heater never failed. Love this thing. As an added bonus. It saved our bacon when the tornados came through and we were with out power for a week. Just fuel for the generator and a grill propane tank. We were never without hot water. ## Frequently Bought Together - FOGATTI RV Tankless Water Heater, InstaShower 8 Plus, Gen 2, with 15 x 15 inches Black Door and Remote Controller, DC 12V, Best High Altitude Performance, Ideal for RVers' Everyday Use - Dicor BT-1834-1 Butyl Seal Tape - 1/8" x 3/4" x 30' Repair Tape for RV, Trailer, Motorhome, Window, and Vent Sealing - Camco 10423 1/2" Temperature and Pressure Relief Valve with 4" Epoxy-Coated Probe , Brown --- ## Why Shop on Desertcart? - ๐Ÿ›’ **Trusted by 1.3+ Million Shoppers** โ€” Serving international shoppers since 2016 - ๐ŸŒ **Shop Globally** โ€” Access 737+ million products across 21 categories - ๐Ÿ’ฐ **No Hidden Fees** โ€” All customs, duties, and taxes included in the price - ๐Ÿ”„ **15-Day Free Returns** โ€” Hassle-free returns (30 days for PRO members) - ๐Ÿ”’ **Secure Payments** โ€” Trusted payment options with buyer protection - โญ **TrustPilot Rated 4.5/5** โ€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.au/products/340538180-2-9-gpm-rv-water-heater](https://www.desertcart.com.au/products/340538180-2-9-gpm-rv-water-heater) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-08-24*
