Why Do You Get Warm Standing in Front of a Fireplace?
When winter comes, families light a fire in the fireplace and sit around or stand in front of it to warm up. Have you ever thought about why you get warm and the difference between sitting around and standing by the fireplace?
If you stand in front of your fireplace, you will get more heat than sitting around the fireplace. But how does this happen and why can you warm yourself up? Let’s know more about this comfortable experience in the cold winter.
Why do you get warm standing in front of a fireplace?
Reality shows that you can get more heat by standing in front of your fireplace than sitting around it. You may know that the hot air is lighter than the cold air, so the heat goes up, allowing you to get more heat when standing.
But there are deeper reasons. And how can the fire warm your body up? It happens in three steps.
Step 1: Radiation
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium. During the process of combustion, the chemical energy inside your woods is transformed into heat energy and the fire is emitting this radiation in all directions, including the heat we feel.
Step 2: Convention
In the process of radiation transfer, there should be a medium and the energy passes from one medium to the next one, and so does heat. When we stand in front of the fireplace, it’s the air that serves as the medium for this convention.
Step 3: Conduction
Conduction is the process by which heat or electricity passes through or along with something. In the case of fire, the radiation of heat touches your body and makes the temperature rise.
There is a principle that thermal energy (heat) only goes in one direction: from hot to cold. The fire of wood is about 600 to 1600 degrees. Your body is distinctly colder than the fire and the heat will be transported to your body by air.
When you stand up, you expose the entire surface to the air and the contact area reaches a maximum, which allows the most heat to interact with your body.
Is it bad to sit in front of a fireplace?
The heat of the fire makes your body warm, but it doesn’t come without disadvantages.
In the combustion process, it releases plenty of smoke which contains visible and invisible fine grains. The smoke may result in asthma and bronchitis. Therefore, it is likely to sit or stand in front of the fireplace for a long time because it might do harm to your health.
The heat powered wood stove fan is designed to help you with that. For example, Signstek heat powered wood burning stove fan fit for rooms up to 430ft2. This magical fan circulates the heat around the fireplace, balances the temperature, and allows hot air to circulate efficiently and quickly throughout the room, allowing you to enjoy a warm environment in winter.
With our heat powered fan, you no longer need to sit or stand close to the fire, which significantly reduces the risk of asthma and bronchitis caused by the wood-burning smoke.
Moreover, our motor is imported from Japan, runs more smoothly than a normal motor, and makes almost no sound.
