Bosch Therm 520 HN LP (Liquid Propane) Whole-House Tankless Water Heater

Bosch Therm 520HN Tankless Water Heater

The Bosch Therm 520 HN incorporates an evolutionary hydro-power ignition system which allows this tankless water heater to work without a standing pilot, grid connection or battery! A small turbine inside the water heater uses the energy from the flowing water to ignite the burner. The modulating gas valve then maintains a constant temperature at varying flow rates. This innovative technology, patented by Bosch, makes this an ideal product for installations without access to electricity or regions prone to inclement weather and power outages.

This 117,000 BTU/hr maximum input heater has enough power for running a shower and a sink simultaneoulsy.

The Bosch Therm 520HN is the direct replacement for the Bosch GWH 425 HN and the Bosch AquaStar 1600H and the Bosch AquaStar 125HX.

PLEASE NOTE: THIS PRODUCT IS NOT AVAILABLE FOR SALE IN CALIFORNIA.
