Check the listing for details. FOGATTI RV Tankless Water Heater InstaShower 7 with 15 x 15 in Black Door DC 12V. Color: Black, Condition: New. Listed at 459.99 USD. FOGATTI RV Tankless Water Heater, InstaShower 7, Gen 2, with 15 x 15 inches Black Door and Remote Controller, DC 12V, Optimized Summer Comfort Performance, Ideal for RVers' Family Use Product Details Ideal Option for Replacing Existing Water Heater: On-demand tankless water heaters are different from capacity-limited tank water heaters, they truly achieve endless hot water supply throughout the whole day. So Fogatti InstaShower 7 is the ideal option for replacing Suburban and Atwood's 6 gallons tank water heaters, as well as Girard and Furrion tankless water heaters. If you previously used a 10 & 12 gallons tank water heater, it would need to be retrofitted with an 18 x 18 inches door. Incessant Hot Water: Tankless 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 is no need to waste 20-30 minutes waiting for hot water in the middle of the shower. But tank water heaters can only store up to 6-10 gallons of hot water and run out in 10-15 minutes. Unique and Distinctive Features: 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. Reduce Costs and Worries of RVers: Fogatti has always thought of RVers, 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 a 6.6ft-long intelligent remote controller, saving the expense of Installing these. 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.
