What makes this product green?

  • Conserves water
  • Energy-conserving equipment


Navien offers ultra-efficient tankless condensing water heaters for commercial and residential applications. Microprocessors and sensors in these units monitor air and gas pressure to maintain the optimal gas-to-air ratio, leading to reduced emissions and improved combustion and energy efficiency—these water heaters have an energy factor of 0.98. Navien uses stainless steel condensing heat exchangers instead of copper, minimizing corrosion and lime build-up and improving performance and durability. The “A” model has a built-in circulation pump and buffer tank and can deliver heated water at flow rates as low as 0.1 gpmGallons per minute. Measure of liquid (usually water) flow. (most tankless heaters require a minimum flow of 0.5 gpm). Multiple units can be joined together via the company’s Ready-Link system and controlled by a single remote, so they can be configured for large commercial systems as well as residential use. Warranties provide coverage for 12 years (CR model) or six years (CC model) for heat exchangers, and three years for parts (all models).
