A baffle is a device installed in the flue pipe of a gas water heater to improve efficiency by slowing the flow of hot exhaust gases. This increases heat transfer to the water before the gases exit the vent, boosting overall performance and reducing energy waste.

What does a baffle do in a water heater?
It slows exhaust gases inside the flue so more heat transfers to the water, improving efficiency and reducing energy loss.

Baffles slow exhaust flow to increase heat transfer efficiency.
In residential and commercial gas water heaters, baffles help capture more heat from combustion gases, improving efficiency and extending equipment life.
Have the baffle and flue inspected and cleaned during routine service to prevent soot buildup and maintain safe operation.
“Have the baffle and flue inspected and cleaned during routine service to prevent soot buildup and maintain safe operation.”
Baffles are used in many heat-transfer applications, from boilers to cooking equipment, to improve efficiency.
Can a baffle be removed to improve airflow?
No. The baffle is designed to improve heat transfer and safety, so it should not be removed.
How often should a baffle be cleaned?
It should be inspected during annual maintenance and cleaned if soot or debris is present.
Do all water heaters have baffles?
Most gas water heaters use baffles, but designs vary by manufacturer and model.
