Water Heaters - Capacity

The water heater temperature setting strongly impacts the amount of usable hot water available for showers and baths. 

• Safety regulations require a factory setting no greater than 125°F (52°C) for all new water heaters. Therefore, if your old water heater was set to a hotter temperature than your new water heater with a factory set setpoint of 120°F (49°C), the new water heater may seem to provide lower capacity than your old water heater. This can be corrected by increasing the temperature setpoint.
• If more hot water capacity is desired, increasing the temperature from 120°F to 135°F (49°C to 57°C) will enable the same tank of hot water to last about 25% longer because less hot water is mixed in at the shower or faucet.
• Increasing the water temperature setpoint may improve the cleaning performance of dishwashers and washing machines.
• The user can adjust the temperature setting to meet their needs. Always read and understand the safety instructions contained in the Owner’s Manual before adjusting the temperature setpoint. Download a copy of the Owner's Manual.
