Navien condensing tankless water heaters provide an unlimited amount of hot water at a steady temperature, whenever you need it, for as long as you need it.  Because this product has an industry leading efficiency rating of 98%, you can cash in on low annual operating costs as well as receive the best payback when compared with conventional tank-type water heaters.

Navien's two microprocessors offer better control and safer operation by continuously cross monitoring each other's performance to assure proper operation at all tmes.  These two microprocessors not only control the burner for ideal combustion but also maintain the steady hot water temperature.  Navien tankless water heaters also utilize dual stainless steel heat exchangers, providing 20 times more resistance to erosion and condensation damage than copper heat exchangers.  Standard 3" PVC pipe can be used for venting, and Navien tankless water heaters are capable of runs up to 100 feet with 6 elbows.

Standard Features:

  • 98% Efficiency
  • Dual stainless steel heat exchangers
  • Higher efficiency allows the use of PVC or plastic venting
  • Two mcroprocessors offer better control and safer operation
  • Air Pressure Sensor maximizes combustion efficiency
  • Gas Pressure Sensor offers stable combustion
  • Built-in leak detector

A federal energy efficiency tax credit of up to $1,500 is available for this product if placed in service from January 1st, 2009 to December 31st, 2010. The tax credit covers 30% of the equipment, installation supplies and labor costs up to $1500.

Maximum Input BTU

The maximum amount of heat that the unit can produce. The amount delivered into the space will be the input minus the efficiency loss also know as the output. For example a 100000 btu furnace at 80% efficiency will give you 80000 out btus of heat. The same size furnace at 95% will give you 95000 btus of heat.

Maximum Input BTU
175,000 BTU
Minimum Input BTU

The amount of heat produced by the unit at the lower stage of heat. Having two stages of heat will allow for more consistent operation and greater comfort in the home.

Minimum Input BTU
17,000 BTU
Hot Water Capacity Range

The gallons per minute of hot water that the unit is rated to provide. The actual amount of hot water generated can vary depending on your ground water temperature.

Hot Water Capacity Range
0.5 - 9.8 GPM
Thermal Efficiency

The percentage of the heat generated by combustion that goes into heating. The remaining percentage goes out the flue. The higher the efficiency rating, the lower the cost of operation.

ENERGY STAR® Qualified

Products earn the ENERGY STAR label by meeting the energy efficiency requirements set forth in ENERGY STAR specifications. The EPA establishes these specifications based on the following set of principles:

  • Product categories must contribute significant energy savings nationwide.
  • Qualified products must deliver the features and performance demanded by consumers, in addition to increased energy efficiency.
  • If the qualified product costs more than a conventional, less-efficient counterpart, purchasers will recover their investment in increased energy efficiency through utility bill savings, within a reasonable period of time.
  • Energy efficiency can be achieved through broadly available, non-proprietary technologies offered by multiple manufacturers.
  • Product energy consumption and performance can be measured and verified with testing.
  • Labeling would effectively differentiate products and be visible for purchasers.
