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 per year over conventional tank type gas water heaters and $40 per year over conventional tankless gas water heaters.
Shortest payback of any tankless water heater on the market. Best gallons per minute performance when comparing input BTU.
Ultra efficient burner uses less gas resulting in substantial CO2 and NOx emissions reductions. Less NOx and CO2 means less acid rain and less green house gases minimizing ozone layer depletion.
Navien’s dual stainless steel heat exchangers are up to 20 times more resistant than copper heat exchangers to erosion and condensation damage.
The highest 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 saving and much easier installations. 3” PVC venting runs to 100” with 6 elbows.
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 Sensor) 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 Sensor) 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.
Built-in leak detector 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: get hot water even at very low flow rates of 0.1 or 0.2 GPM. 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 (NR-10DU)
Advanced water heater diagnosis capability and error feedback. Touch activated backlight function and Easy-to-Use button type control. Built-in recirculation timer for water and energy savings. Key-pad lock button prevents inadvertent temperature changes. Temperature adjustment in 1°F increments.
