Yes, a chimney damper is necessary. It controls airflow in and out of your fireplace, helping to retain heat when closed and allowing smoke to escape when open. Without a damper, your home could lose warmth during cold months, leading to higher energy bills. It also helps prevent downdrafts and keeps animals or debris from entering the chimney. In short, it’s essential for efficiency and safety.

According to the U.S. Federal Emergency Management Agency, keep a disaster preparedness kit in your home with enough essentials to sustain your family for at least 72 hours.

A fireplace hearth is necessary in most areas per building codes, especially for gas and wood-burning fireplaces. Electric fireplaces may not require a hearth, so check local building codes or ask a pro for guidance if you’re leaning toward electric. A fireplace hearth can decrease the risk of flying embers creating a fire and burning your home down. That’s why fireproof material, like tile, is used for the hearth.

A chimney liner isn’t required for an outdoor fireplace; you don’t technically need one if the masonry chimney uses the proper dimensions and is built to code. However, a chimney liner does serve as a protective coating for the flue. Adding a liner could improve performance, safety, and durability. In short, while not necessary, it wouldn’t hurt.
