A gel fireplaces perfect for renters. No need to hunt around for a rental with a fireplace; you can bring one right along with you. There’s no need to worry about a fireplace that is in your rental either. Often times, fireplaces fall into disrepair and may have a lot of creosote in the flue or may not draw enough air. As such, smoke ends up in the home, which can carry with it carbon monoxide, nitrogen dioxide and sulfur dioxide.
