Tankless water heaters are compared by power and flow rate, whereas hot water tanks are compared by capacity, recovery rate, and first hour rating. Assuming you will never use more hot water than your water heater flow rate, you will never run out of hot water! This means that you have an unlimited capacity, zero recovery rate, and unlimited first hour rating.
Flow rate is measured in gallons per minute (GPM) based on the given heat rise (50-80 degrees). Tankless water heaters range from 4 to 9 GPM.
Tankless water heaters are typically 82% to 98% efficient. Tankless water heaters also maintain their efficiency over time, unlike hot water tanks which are subject to sediment accumulation.
The average cost is $3,500 to 4,100 for a new installation. Some factors affecting price include:
» Cost to run a dedicated gas like to the tankless water heater
» Installation of category 3 stainless steel venting or System 636 flue gas venting
» Installation of additional piping to relocate tankless water heater
» Installation of dedicated power to the tankless water heater
» Installation in under-construction home
» Retrofit from an existing tankless water heater
