Hot water and whole-house comfort from Navien, a global leader in high-efficiency water heaters and boilers. Whether you need an endless supply of hot water, efficient home heating, or both, Navien has the most energy-efficient solutions. Navien offers the industry's most advanced condensing tankless water heaters, condensing boilers, and the first combi-boilers strong enough to support whole-house heating and hot water for larger homes.
Tankless Water Heaters
Navien Premium Efficiency condensing tankless water heaters are the #1 selling high-efficiency condensing tankless water heaters in North America. The NPE-2 series offers ultrahigh efficiency up to 0.96 UEF to keep your utility bills low, endless hot water, and exclusive ComfortFlow® technology with a built-in recirculation pump and buffer tank.
A tankless water heater is a type of water heater that doesn't use a storage tank to heat water. Instead, hot water is produced only when needed. Tankless water heaters are smaller and more efficient than traditional water heaters. Navien offers models of tankless water heaters that use either condensing or non-condensing technology.
Combi-Boilers
Navien combination boilers provide endless hot water and whole-house heating for small and large homes. Navien offers two premium combi-boiler series: NCB-H and NFC-H. Both are high efficiency and high capacity, with NFC-H having a larger heating output.
Boilers
Navien high-efficiency condensing boilers provide whole-house heating for small and large homes. Wall-mounted residential boilers from Navien save space and energy.
Conventional Boilers Lose Heat. Condensing Boilers Retain It.
Reduce energy costs and greenhouse gasses with Navien high-efficiency condensing boilers. Condensing boilers operate more efficiently than traditional boilers because they have a stainless steel heat exchanger that captures heat from exhaust vapor and transfers the recovered heat energy to the water circulating in the hydronic heating system.
