A chimney cover is an important accessory that can be used to prevent wind drafts, rainwater and birds from going in the chimney through the top. With a wide array of options, designs and various materials, you have your work cut out for you as far as acquiring the right type of cover goes. Fortunately, however, there are three main things you need to be aware of so that you can narrow down the options that are available so that you can choose the ideal one.
Some chimney covers are specifically made for chimneys that runs on different types of fuels such as solid fuel, wood, oil or gas. However, most of them are ‘multi-fuel’. Most people tend to purchase multi-fuel covers, but if you are in the midst of burning something which is especially hot, or something that emanates an abundance of smoke, then you may experience some difficulty. Therefore, check to see the cover’s list of compatible fuel types so that you can choose one that matches your fireplace/stove. It’s also worth noting that the fuel type will affect the size which is in litres. In general, the more litres the cover rates for, the more smoke it will be able to move out at once. Meaning, the more litres it rates for, the more efficient it will be when it comes to covering an especially fireplace.
The next thing you’ll need to consider is size. Most covers come in 5, 6 and 7 inches to match the size of the liners of the chimney. Even though this may seem small, typically what happens is that the cover is essentially fit into the flu of the chimney. The point being is that before you choose a cover, you’ll need to measure the top portion of the chimney, the flu and the external size of the chimney itself.
In all actuality, there are several different kinds of chimney covers that are available and each one has their own unique set of distinctive advantages. A standard chimney cover fits over the top portion to prevent rain as well as debris. These usually come in terracotta, stone and stainless steel. On the other anti-downdraught covers prevent wind drafts from going down. Meanwhile spinning chimney covers prevent wind drafts from going in, but also do a great job of providing an adequate amount of ventilation for smoke and bird covers are mostly used just for the sake of keeping birds out of the chimney.
