Description
A. O. Smith's Signature Series tankless natural gas hot water heater uses up to 140, 000 BTU/h of natural gas or propane to deliver a 6.6-gallons-per-minute flow rate (based on a 35°F rise) of continuous hot water when sized appropriately. This makes it ideal for whole-home applications. This model only heats water when needed, making it one of the most energy-efficient options for heating water. This non-condensing outdoor compact water heater has a 0.81 Uniform Energy Factor (UEF), reducing energy consumption and saving money on energy bills. You can easily mount this model on an outside wall, saving valuable storage space. This unit may qualify for additional energy-efficiency rebates and tax credits in your local area.
