purchased the Ranein Propane Gas Tankless Water Heater, Indoor 3.6 GPM, 80,000 BTU model, and overall I have been very pleased with it. The unit is compact, efficient, and provides hot water quickly without taking up the space of a traditional tank-style water heater. Installation was straightforward, and once properly set up, the water heater performed well. The propane operation is a great option for areas where electric capacity may be limited, and the tankless design helps reduce wasted energy since it only heats water when needed. The 3.6 GPM flow rate works well for normal household use, especially for smaller homes, cabins, apartments, or situations where one or two fixtures may be used at a time. The water temperature has been consistent, and the unit feels well-built for the price. Overall, this is a solid tankless propane water heater for anyone looking for an indoor, space-saving, and efficient hot water solution. I would recommend it to buyers who understand the installation requirements and want reliable hot water without a bulky storage tank.
