What are the advantages of gas fireplaces?

Gas prices start at around $800 installed plus another cost of about $150 per year on gas depending on usage habits. Also, since this type has flames involved which means it’s capable of heating up rooms more effectively than electric units or pellet stoves which don’t have open flames to generate heat with, this type is typically the most expensive option overall for supplemental/secondary heater purposes (about $200-$400+ per month even if you use one sparingly).
