What is the chimney?

The chimney of the chimney is a rotary metal fan that fits over a smoke or chimney pot to stimulate updraffts and prevent the Nowraft. Most importantly, it prevents the wind from blowing the smoke back down the chimney and the room under. The chimney hood also prevents birds and squirrels to nest in the chimney and often act as a rain guard. Sometimes it is referred to as a smoke tie or chimney cap, most often called the bonnet because it is shaped as a hood or bonnet and resembles a cowl wears a monk. Traditionally, it was made in the same red color as chimney pots, but today it is usually made of galvanized iron and is available in different styles. In wind conditions, however, the wind force can be stronger than updraft warm air and smoke and can push the flow back down Chimney Flue. This rear dive can result in a bad fire, or could drive smoke and toxic gases back to the house. Cowl chimney stabilizes fluctuating smoke concepts, prevents Nowraft and increases smoke drawing, whichIt maximizes fuel combustion efficiency and ensures a healthy environment.

The most effective type of chimney is H-POT or H Cowl. It has a significant advantage over most other fasteners because it stabilizes the thrust rather than increases it, which allows the fireplace to work more efficiently. Made of chimney pipes in letter H, it insulates the combustion gases from the wind and turbulence that cause the dive. The H-Cap was originally most prominently used in marine applications because of its voluminous appearance, but because of its functionality energy saving has recently become popular.

Today, the term "chimney cowl" is used freely and can refer to a terminal or ventilation that fits into an existing chimney. Inserting fatty fuel, such as push-in bonnet or type push-in, can also be called a chimney bonnet. Chimneys that are no longer in operation can use mushrooms in the shape of a bonnet or bonnet bonnet that soThey call Cowls. They have round or square bases that act as openings for smoke openings, but are safe only in unused chimneys.
