Review & Description

The 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 modulatinggas 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. * Patented Hydro-power ignition requires no electricity * 80% thermal efficiency * 117,000 BTU maximum input * 5.3 gallons per minute capacity at 35F degree rise * Endless hot water for up to 2 applications at a time * Minimum activation flow rate of 0.6 gallons per minute * High to low temperature control * Vents with galvanized B vent - natural draft * Built for durability and serviceability with 15-year warranty and 20+ year life expectancy * Available in NG and LP models
