WHY NAVIEN CONDENSING WATER HEATERS? 

• ENDLESS SUPPLY OF HOT WATER: NAVIEN CONDENSING TANKLESS WATER HEATERS SUPPLY UNLIMITED HOT WATER AT A STEADY TEMPERATURE WHENEVER YOU NEED IT AND FOR AS LONG AS YOU NEED IT.  NAVIEN WATER HEATERS CREATE A MORE COMFORTABLE LIVING ENVIRONMENT.
• ULTRA CONDENSING EFFICIENCY: THE INDUSTRY'S HIGHEST ENERGY EFFICIENCY AT 98% MEANS THE LOWEST ANNUAL OPERATING COSTS AND THE BEST PAYBACK COMPARED WITH CONVENTIONAL TANKLESS OR TANK-TYPE WATER HEATERS. SAVES, ON AVERAGE, MORE THAN $160.00 PER YEAR OVER CONVENTIONAL TANK TYPE GAS WATER HEATERS AND $40.00 PER YEAR CONVENTIONAL TANKLESS GAS WATER HEATERS. SHORTEST PAYBACK OF ANY TANKLESS WATER HEATER ON THE MARKET. BEST GALLONS PER MINUTE PERFORMANCE WHEN COMPARING INPUT BTU
• ECO-NAVIEN TECHNOLOGY: ULTRA EFFICIENT BURNER USES LESS GAS RESULTING IN SUBSTANTIAL CO2 AND NOX EMISSIONS REDUCTIONS.  LESS LOX AND CO2 MEANS LESS ACID RAIN AND LESS GREEN HOUSE GASES MINIMIZING OZONE LAYER DEPLETION.
• EXTENDED LIFECYCLE: NAVIEN'S DUAL STAINLESS STEEL HEAT EXCHANGER ARE UP TO 20 TIMES MORE RESISTANT THAN COPPER HEAT EXCHANGERS TO EROSION AND CONDENSATION DAMAGE.
• EASY VENTING: THE HIGHER EFFICIENCY OF NAVIEN WATER HEATERS RESULT IN LOWER EXHAUST TEMPERATURES THAT ALLOW THE USE OF PVC OR OTHER PLASTIC VENTING MATERIALS. PLASTIC VENTING OFFERS SIGNIFICANT COST SAVINGS AND MUCH EASIER INSTALLATIONS. 3" PVC VENTING RUNS TO 100' WITH 6 ELBOWS.
• ADVANCED TECHNOLOGY: ENHANCED SAFETY WITH DUAL MICROPROCESSORS - NAVIEN'S TWO MICROPROCESSORS OFFER BETTER CONTROL AND SAFER OPERATION BY CONTINUOUSLY CROSS MONITORING EACH OTHER'S PERFORMANCE TO ASSURE PROPER OPERATION AT ALL TIMES.  THESE TWO MICROPROCESSORS NOT ONLY CONTROL THE BURNER FOR IDEAL COMBUSTION BUT ALSO MAINTAIN A STEADY HOT WATER TEMPERATURE.   
  
   - OPTIMAL AND STABLE COMBUSTION WITH APS AND GPS
  APS: AIR PRESSURE SWITCH MAXIMIZES COMBUSTION EFFICIENCY BY SENSING AND CONTROLLING THE AIR REQUIRED FOR OPTIMAL COMBUSTION EVEN IN HIGH WIND LOCATIONS OR IN INSTALLATIONS WITH LONG VENT RUNS.
  GPS: GAS PRESSURE SWITCH OFFERS STABLE COMBUSTION BY SENSING GAS PRESSURE AND CONTROLLING THE FAN SPEED TO MAINTAIN OPTIMAL COMBUSTION EVEN UNDER A WIDE RANGE OF CHANGING GAS PRESSURE.
  LEAK DETECTOR IS BUILT INTO THE UNIT PREVENTS DAMAGE TO THE WATER HEATER AND TO PERSONAL PROPERTY CAUSED BY A WATER LEAK.
• BUILT-IN CIRCULATION PUMP WITH MINI BUFFER TANK ("A" MODEL ONLY) DELIVERS HOT WATER TO FIXTURES QUICKLY RESULTING IN WATER CONSERVATION. NO MINIMUM FLOW RATE.  ELIMINATES ANY HOT/COLD HOT STACKING, THE SO-CALLED "COLD WATER SANDWICH".  SAVES ADDITIONAL MONEY AND TIME BY ELIMINATING THE PUMP PURCHASE COST AND ON-SITE INSTALLATION COSTS.  PREVENTS HEAT EXCHANGER FROM FREEZING.
• REMOTE CONTROL: ADVANCED WATER HEATER DIAGNOSIS CAPABILITY AND ERROR FEEDBACK.  TOUCH ACTIVATED BACKLIGHT FUNCTION AND EASY-TO-USE BUTTON TYPE CONTROL. BUILT-IN RECIRCUATION TIMER FOR WATER AND ENERGY SAVINGS. KEY-PAD LOCK BUTTON PREVENTS INADVERTENT TEMPERATURE CHANGES.  TEMPERATURE ADJUSTMENT IN 1 DEGREE INCREMENTS.
