If you are considering adding a fireplace to your space the four main types are gas, electric, vent free/ ethanol burning, and a traditional wood burning fireplace. The gas fireplaces tend to give the best flame and look the best, but are also expensive. Gas fireplaces require a connection to the outdoors to have ventilation.
Ethanol and electric fireplaces are vent free are less expensive to install. If there are apartment code restrictions you may want to consider a vent free fireplace. The fireplace is a gas fireplace we had installed in a client’s residence in Chelsea. They were fortunate to have an outdoor patio close enough to the family room for ventilation.
