HOT WATER WHEN YOU NEED IT TO BE HOT!
What Flow rate (gallons per minute or GPM) needs do you have?
In the chart, each row represents the capacity of one tankless water heater unit. Cooler climates will restrict the flow rate because the temperature rise is steeper. Most tankless units are rated at the capacity for warmer climates. Units with GPM lower than 3 should be considered point-of-use tankless water heaters.
