Rinnai SE+ 9 GPM Outdoor Condensing Tankless Water Heater with ThermaCirc360 - LP

The Rinnai SE+ Series with ThermaCirc360 9 GPM Outdoor Condensing Tankless Water Heater is a high-capacity, propane-powered tankless water heater designed for outdoor installation. It can deliver up to 9 gallons of hot water per minute, making it well-suited for large households or use in commercial settings where high demand for hot water is expected.

This water heater is a condensing model, which means it uses a secondary heat exchanger to capture additional heat from the exhaust gases, increasing its overall efficiency. It is equipped with advanced features, such as a digital temperature control panel and the ThermaCirc360 system, which helps reduce wait time for hot water at fixtures and water waste. The ThermaCirc360 system is a built-in recirculation pump that helps to keep hot water circulating through the pipes, so it's ready when you need it. It also has a dedicated return line, which helps to reduce the amount of cold water that needs to be purged before hot water is available.

The SE+ Series with ThermaCirc360 9 GPM Outdoor Condensing Tankless Water Heater is energy efficient, with a high energy factor of .95, and meets the Energy Star qualifications for energy efficiency. It is also equipped with a built-in freeze protection system, which helps to prevent damage to the unit in cold weather.
