The Dewhot Gas Geyser Cowl – 110mm is an essential safety and performance accessory designed to protect your gas geyser flue while ensuring optimal ventilation. Specially engineered for 110mm flue pipes, this cowl supports proper airflow, enhances combustion efficiency, and prevents dangerous exhaust gases from re-entering your home.
A high-quality flue cowl is critical for any gas geyser installation. The Dewhot 110mm Cowl is designed to improve the draft, allowing combustion gases — including carbon monoxide and other by-products — to exit the flue safely and efficiently. This protects your household from harmful fumes and ensures your geyser operates at peak performance.
One of the main benefits of this cowl is its ability to eliminate downdrafts, which occur when strong winds or atmospheric pressure push exhaust gases back down the flue. Downdrafts can disrupt the burner, reduce efficiency, and create hazardous conditions. The Dewhot Cowl prevents this by directing airflow correctly even during harsh weather.
Built with durability in mind, it also provides excellent weather protection. The cowl shields the flue from rain, snow, and moisture, reducing the risk of corrosion and preventing internal water damage. It also stops leaves, debris, small animals, and birds from entering the flue — a common cause of blockages and unsafe conditions.
By maintaining consistent ventilation and preventing obstruction, the Dewhot 110mm Gas Geyser Cowl helps ensure proper combustion, increased efficiency, and a longer lifespan for your gas geyser.
This cowl is ideal for:
-
Dewhot gas geysers
-
Most 110mm flue pipes
-
Coastal and high-wind areas
-
Homes, lodges, guesthouses, staff quarters, and outdoor shower installations
