An ideal option for replacing existing water heaters, on-demand tankless water heaters are different from capacity-limited tank water heaters. They truly achieve an endless hot water supply throughout the whole day. The Fogatti InstaShower 7 is the ideal option for replacing Suburban and Atwood 6-gallon tank water heaters, as well as Girard and Furrion tankless water heaters. If you previously used a 10 or 12-gallon tank water heater, it would need to be retrofitted with an 18" x 18" door. Incessant Hot WaterTankless water heaters are better than tanked water heaters for continuous showering of multiple people. With 48, 000 BTU of power, Fogatti InstaShower can produce a maximum of 2.5 GPM of hot water so there's no need to waste 20-30 minutes waiting for hot water in the middle of the shower. Tank water heaters can only store 6-10 gallons of hot water and run out in 10-15 minutes. Unique and Distinctive FeaturesThe 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. Reduce Costs and WorriesThe Fogatti InstaShower comes with a pressure relief valve built into the product, so you don't have to buy and install it separately. It also comes with a 6.6' long intelligent remote controller, saving the expense of Installing these. Safety and ReliabilityThe InstaShower 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.• Instant water heater• Incessant hot water• Digital display controller• Freeze protection enables reliable winter use• No need for new LP gas lines or special pipingSpecsModel: InstaShower 7Heat Output: 48000 BTUMax Water Flow: 2.5 GPMDimensions: 15"L x 15"W x 14.3"HMin Clear Opening: 13" x 13"Efficiency: 84%Gas Inlet: 5/8" UNFVent Diameter: 1.97" NPTWater Inlet: 1/2"Water Outlet: 1/2"Water Pressure Range: 14.5 - 116 PSITemperature Range: 95°F - 123°FWater Temp Fluctuation: ±3°FElectric Supply: 12V DCExhaust Type: ForcedIgniting Type: Automatic Pulse IgnitionFuel Type: PropaneCSA Safety and ETL Quality CertifiedSuitable For All RVsDoor is not included 48, 000 BTU of power with a maximum of 2.5 GPM of hot water Includes pressure relief valve built in & a 6.6' long intelligent remote controller Built-in forced exhaust fan on top, stable combustion, & auto gas shut-off | Fogatti InstaShower 7 48,000 BTU RV Tankless Water Heater without Door
