This allows for instant hot water when you need it and energy savings due to a lower standby loss than with traditional tank-style water heaters.

To reset your Navien Tankless Water Heater, you will need a Phillips head screwdriver and a flat-head screwdriver. You may also want to have an adjustable wrench on hand in case the screws are difficult to remove by hand.
