Spinning Cowl Problems

For homeowners looking to optimize their wood-burning stove experience, the installation of a spinning cowl can seem like a straightforward solution to mitigate the pesky issue of down drafts. However, many are finding that this solution is not without its own set of challenges.

The Problem with Spinning Cowls

1. Maintenance Cost: One significant concern with spinning cowls is their requirement for regular maintenance. Yearly servicing, preferably by returning the cowl to the manufacturer, may sound simple. However, this involves several steps and costs: removal labor, scaffold tower hire, roof ladders, postage, the manufacturer’s service charge, and re-installation labor.
2. Loss of Functionality Over Time: Another concern expressed by homeowners is the loss of updraft over time. Even when the vents of the stove are wide open, the updraft can become significantly limited. This is usually due to the spinning cowl ceasing to rotate, hindering its primary function.
3. Wildlife Intrusion: Before switching to wood burners, some homeowners have used cowls that resemble two inverted dishes with central holes. Such designs may lead to occasional down drafts. Additionally, small birds often find their way down the chimney, leading to unwanted indoor surprises.

Possible Solutions

1. Switch to an H Pot: Once a common choice, the H pot has received recommendations for its efficacy. This cowl design is recognized for its ability to prevent smoke from entering rooms, maintaining a clear passage for the smoke to exit.
2. Consider the Vedette Cowl: This particular cowl has been recommended by several users, noting its efficiency in preventing down drafts. Plus, its secure fixing means that it doesn’t obstruct the chimney sweeping process.
3. Address Installation Issues: Some believe that problems with downdraft can arise due to improper installation of the stove or cowl. It’s crucial to ensure that everything is correctly set up from the get-go.
4. Local Conditions & Chimney Stack Height: The height of the chimney stack relative to the roof line can impact the effectiveness of the cowl. In some cases, it might be beneficial to adjust the height of the stack or change the cowl type to better suit local conditions.
5. Avoiding Additional Attachments: A small change, like adding wire mesh to prevent birds from entering, can surprisingly result in significant issues like filling rooms with smoke. It’s vital to consider how any alterations might impact the overall functionality.
6. Consult Experts: Lastly, while researching and gathering personal anecdotes is valuable, consulting with experts who understand the unique conditions and requirements of one’s home is crucial. Whether it’s the chimney sweep, stove installer, or cowl manufacturer, their insights can provide tailored solutions to individual problems.

In conclusion, while spinning cowls offer a promising solution to down drafts, they come with their own set of challenges. Homeowners need to weigh the benefits against the costs and potential issues. Exploring alternative cowl designs and ensuring correct installation might be the key to a smoke-free, warm, and cozy living space.
