Bosch ProTankless™ GWH 425 HNO

Install your tankless water heater outside!

The Bosch ProTankless™ GWH 425 HNO incorporates the same revolutionary hydro-generated ignition system as the GWH 425 HN, allowing the water heater to operate without a standing pilot or electricity. However, the Bosch ProTankless ™ GWH 425 HNO is equipped with built-in freeze protection which does require electricity (120 V AC / 50 Hz).

  • Installs outside – built-in freeze protection to 5°F.
  • Energy factor: .80 NG / .84 LP
  • Thermal efficiency: 80% NG / 83% LP
