Why Upgrade to a Navien Tankless Water Heater?
Traditional tank water heaters heat and re-heat 40 to 80 gallons of water 24 hours a day, draining your energy budget even when you’re asleep. Navien condensing tankless water heaters only heat water on demand, offering unmatched efficiency, comfort, and longevity.

Endless Hot Water: Continuous flow rates mean no running out of hot water mid-shower, even with multiple fixtures running simultaneously.
-
Up to 0.96 UEF Efficiency: Navien condensing technology recovers heat from exhaust gas that traditional units waste, lowering annual gas utility bills by up to 40%.
-
Dual Stainless Steel Heat Exchangers: Resistant to heavy corrosion and scale buildup, offering superior durability compared to copper heat exchangers found in inferior brands.
-
Compact, Space-Saving Design: Wall-mounted units free up valuable floor space in garages, basements, and utility closets.
-
15-Year Limited Heat Exchanger Warranty: Built to last 15 to 20+ years—nearly double the lifespan of standard tank heaters.

“I had a great experience working with Jake when he replaced my hot water heater. From start to finish, he was kind, professional, and really knew what he was doing. He showed up on time and completed the job efficiently. Everything was cleaned up afterward, and the new water heater works perfectly. I’d highly recommend All Hot Water to anyone in need of a water heater service.”
