The Fogatti InstaShower Ultra is a propane-powered tankless water heater designed to deliver continuous hot water for RV use without recovery delays. The Fogatti InstaShower Ultra produces up to 66,000 BTU and supports a maximum flow rate of 3.9 gallons per minute, allowing multiple water sources such as showers and sinks to run simultaneously. It activates at flow rates as low as 0.5 GPM, reducing water waste during low-demand use.
The system incorporates a built-in pre-mix tank to stabilize temperature at startup, eliminating the cold-water burst common in tankless systems. It uses segmented combustion to adjust heat output based on environmental conditions, maintaining consistent performance across varying temperatures and altitudes. HydroShield technology provides windproof and waterproof resistance, supporting operation in changing weather conditions.
