A 4.4 GPM tankless water heater at a 35-degree F temperature rise can provide enough hot water for up to a two bath home
Natural gas tankless water heaters offer the less expensive operating cost verse electric water heaters
No stand-by energy loss or recovery time necessary; a tankless water heater heats water as it passes through a heat exchanger eliminating the need to continuously reheat a tank of water
Five year warranty on heat exchanger and one year limited-warranty on parts
Energy factor is 0.88
Standard concentric vent system (collar， elbow， and 18-3/4 in. termination) is free of charge; additional components may be purchased at minimal cost
Due to intake air flowing through the outer chamber， the exterior surfaces of the flue are cooled by the incoming combustion airflow; in addition to a much cooler flue pipe exterior， the intake air is taken from outside the home
Please note: this heater must vent horizontally (typically through an exterior wall); with this simple system， there is no need for a roof rain cap， complicated condensation drain， anti-freeze/back-draft trap door， or room air cubic feet calculations
Low water pressure ignition; the heater can function at water pressure as low as 8 psi; making this unit suitable for users living at high altitude or those using well water with older or less powerful pumping systems
Key-touch water temperature settings and on-off switch with easy to understand advanced technology display
Electronic control system via computer chip is advanced and extremely reliable; this "no pilot light" design is safe and convenient， using automatic ignition to further your energy savings
Aesthetically pleasing and simple-small design features make this unit easy to use and install as well as unobtrusive if located within view of working or living spaces
