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 97.3%, 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.
The Navien condensing tankless water heater models ending in "A" have a built-in circulation pump and mini-buffer tank. This allows the tankless water heater to deliver hot water quicker, bypass the minimum flow rate cutoff, and it eliminates hot / cold / hot water stacking.
