Bosch 520 HN NG Indoor Natural Gas Tankless Water Heater


Product Description

We ship to Hawaii and Alaska. Inquire for quote.

The Therm 520 HN NG Indoor Tankless Natural Gas Water Heater 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.
