The Ranein 65,000 BTU RV Tankless Water Heater stands out for its high performance and adaptability. With a maximum flow rate of 3.9 gallons per minute, it ensures a steady supply of hot water, which is a significant upgrade over traditional tank water heaters that can run out of hot water quickly. The heater operates on propane gas and requires a 12V power source, making it suitable for most RVs. It is also CSA certified, ensuring safety and reliability during use.
A major advantage is its thermostatic chamber, which helps maintain a consistent water temperature between 95°F and 124°F, preventing overheating and conserving propane. The inclusion of a multi-function remote control adds convenience by allowing users to monitor gas usage, voltage, and other functions from a distance. Installation is simplified with the unit's ability to replace existing Suburban and Atwood's tank water heaters, though buyers should note that the door kit must be purchased separately.
It is designed for high-altitude use and includes safety features like an anti-freeze device and automatic gas shut-off.
The FOGATTI InstaShower 7 is a solid choice for RV owners looking for a reliable tankless water heater. It offers a strong flow rate of 2.5 gallons per minute with a heat output of 48,000 BTU, which is enough for multiple family members to enjoy hot water without waiting. Running on 12V DC power and boasting an 84% energy efficiency, it’s designed to save fuel by heating water only when needed. The unit is fairly compact (12.7" x 12.7") and weighs about 25.7 pounds, making it suitable for wall mounting in most RVs. It comes with three door size options (sold separately) to fit existing heater cutouts, which simplifies replacement or upgrades. Temperature control is user-friendly via a remote controller, allowing adjustments between 95°F and 123°F, plus special features like staged combustion help keep water temperature steady without cold or scalding spots.
Safety is well-covered with built-in protections including dry combustion prevention, overheat protection, antifreeze defense, and an automatic gas shut-off. The heater also works well at high altitudes, which is a plus for mountain RV trips. On the downside, the door panels cost extra and the unit requires a gas supply (not electric) which might need some plumbing know-how during installation. Also, while the heater is efficient, it still uses propane gas, so fuel consumption should be considered.
The FOGATTI InstaShower 7 provides dependable and efficient hot water delivery for families on the road. Its thoughtful safety and comfort features make it a practical solution, though installation and selecting the correct door size may require some effort.
