Buying Guide: Arched Gas Fireplaces For Your Space
What to consider when choosing an arched gas fireplace insert. Ventless operation simplifies installation but requires room ventilation compliance. BTU rating determines heating area; larger rooms need higher BTU and sometimes a remote control for easy adjustments. Fuel options (natural gas vs propane) depend on your home’s gas supply and propane availability. An arched design enhances aesthetic compatibility with traditional mantels and built-ins.
