Gas Fireplace vs Electric Fireplace: Which Is Cheaper to Run?
By GasFireplaceFixer.com · Gas Fireplace Repair Guide
The cost difference between gas and electric fireplaces depends heavily on your local utility rates, how often you use the fireplace, and whether you need supplemental heat or just ambiance. This guide breaks down the real numbers so you can make an informed decision.
Operating Cost: Gas vs Electric
A gas fireplace typically costs $0.25–0.75 per hour to operate depending on your gas rate and the BTU output of the unit. An electric fireplace running at 1,500 watts costs approximately $0.15–0.25 per hour at average US electricity rates of $0.12–0.17/kWh. In most US markets, gas is cheaper per hour of actual heat output — but electricity wins in mild climates where you primarily want ambiance rather than heat.
Installation Cost Comparison
Electric fireplaces have dramatically lower installation costs — a plug-in unit can be installed for $200-800 including the unit itself. Built-in electric units cost $500-2,500 installed. Gas fireplace installation costs $2,000-5,000 for a direct-vent unit including gas line work, venting, and the appliance. The higher upfront cost of gas is typically offset by lower operating costs over time in cold climates.
Heating Efficiency
Modern gas fireplaces are 70-85% efficient, meaning most of the gas energy becomes heat in your room. Electric fireplaces are 100% efficient at the point of use — all electricity becomes heat. However, electricity generation at the power plant is typically 30-40% efficient, making the total system efficiency of electric heat lower than it appears. In terms of actual heat output per dollar, gas wins in most US markets.
Maintenance Costs
Electric fireplaces have minimal maintenance costs — occasional bulb or LED replacement and glass cleaning. Gas fireplaces require annual professional servicing ($150-250/year) and periodic component replacement. Over a 10-year period, expect to spend $1,500-2,500 on gas fireplace maintenance compared to $100-300 for electric.
Which Should You Choose?
Choose gas if you live in a cold climate, want meaningful supplemental heat, already have a gas line, and plan to use the fireplace regularly during the heating season. The higher upfront and maintenance costs are justified by lower operating costs and superior heat output. Choose electric if you live in a mild climate, want ambiance without significant heat, rent your home, or want zero maintenance hassle. Electric is also the only option if you don't have access to natural gas.
