The Dickinson Barometric Damper is an essential flue component designed to regulate chimney draft in diesel heaters and marine stoves, ensuring consistent and efficient combustion. Installed in the flue system, it automatically adjusts airflow to maintain optimal performance—even in gusty wind conditions.

Constructed from marine-grade stainless steel, this damper is built to withstand harsh marine environments while delivering long-term reliability. It is typically installed as the first section of flue pipe above the heater, helping stabilise draft and improve overall heater operation.

By controlling excessive draft, the barometric damper allows your heater to burn fuel more efficiently and at lower settings, reducing fuel consumption and improving heat consistency—particularly important for offshore and cold-weather boating.

Available in 3", 4", and 5" flue sizes, it is compatible with a wide range of Dickinson diesel heaters and stoves.

Why Choose the Dickinson Barometric Damper? 

For New Zealand boat owners, maintaining stable heater performance in changing weather conditions is critical. Wind gusts and long flue runs can cause excessive draft, leading to inefficient burning and temperature fluctuations.

The Dickinson Barometric Damper solves this by automatically balancing airflow, helping your heater run cleaner, safer, and more efficiently. It’s especially recommended for installations with longer chimneys (over ~1.8m / 6ft) or exposed offshore setups.

This makes it a must-have upgrade for Dickinson heater installations, improving both comfort and fuel economy onboard.
