I installed this Bosch Therm 520 HN LP Tankless water heater in my home with a Rheem RTG20220AB Webstone Tankless Service Valve kit and six feet of 5"-Diamete B-Vent stove pipe. This water heater uses a new technology that requires NO ELECTRICITY or battery power. The water turns an internal turbine which generates electrical spark to ignite the heater burner fed by a propane bottle.
