Next to indoor plumbing, a furnace may be the second-best invention made by modern man, but that doesn’t stop people from cozying up crackling fires during the cold autumn and winter months. Sometimes, there’s nothing more mesmerizing or romantic than a fire in the fireplace in your living room or master bedroom.
Before we had HVAC systems, we relied on fire to keep us warm both outdoors and indoors, but that coziness may be an illusion more than a good heat source. Instead of heating up your home, the fire is probably taking the warm air in the room and sucking it up through the chimney.
Even if you don’t have a fire removing the warm air from the room, a poorly sealed fireplace and chimney can allow the heated air from the heater to escape.
What Can You Do to Counteract Heat Loss?
Without getting into the scientific explanations for why heat escapes through a fireplace and chimney, we’ll shift our focus on what you can do at home to counteract the heat loss that occurs when you have a fireplace in your home.
Here’s what you can do:
- You can install a fireplace insert, which is a lot more effective at limiting heat loss than simply using a glass barrier that sits in front of the fire.
- When the fire isn’t burning, close the damper. This way, you can keep the warm air in the room.
- If the damper is old or worn out, or if it won’t seal right. To solve this, you can purchase an inflatable chimney plug.
- When the fire is hot, keep the damper partially closed.
- If you don’t have one, put a glass barrier in front of the fireplace. However, if you block all the airgoing to the fire, the fire will go out.
