EZ Tankless EZSUPNG Supreme Indoor Tankless Water Heater 8.2 GPM 165000 BTU Natural Gas Direct Vent Kit Manufacturer RFB
The EZ Supreme is a whole home water heater designed for households of 1-3 bathrooms, averaging between 5 -7 GPM. The EZ Supreme is also a self regulating water heater, meaning the heater automatically adjusts the burners according to the water flow to ensure the desired temperature is reached at your tap. Simply set the temperature on the screen and the heater does the rest of the work for you! For instance, the average sink tap runs about 1 gallon per minute while the average shower head runs about 1.7 - 2 gallons per minute. With this in mind, the EZ Supreme can easily handle any two hot water taps running simultaneously and in some cases three!
