| Electric Resistance Fireplace | 1,350–1,500 W Approximately 4,600–5,100 BTU/h | Usually up to about 400–1,000 sq. ft., depending on insulation, ceiling height, climate, and room layout | No chimney, gas line, or special ventilation required; plugs into a suitable electrical outlet | LED-generated flame effect; flame can usually operate without heat | Uses electricity when the heater is on; operating cost depends on local electricity rates and thermostat settings | Overheat protection, automatic shutoff, cool-touch controls, stable cabinet, and a properly rated power cord | Most homes, apartments, and rooms where simple installation is important | High |
| Electric Infrared Fireplace | Typically up to about 1,500 W Output varies by model | Often marketed for larger areas, but actual comfort depends strongly on room insulation and air circulation | No venting or fuel storage required; requires a suitable electrical outlet | LED-generated flame effect, often usable with heat switched off | Electricity is consumed during heating; infrared elements may provide more direct warmth to people and nearby objects | Overheat protection, automatic shutoff, thermostat control, tip-resistant cabinet, and certified electrical components | Living rooms, offices, and spaces where direct radiant warmth is preferred | High |
| Gel-Fuel Fireplace | Approximately 2,000–3,000 BTU/h per fuel can Varies by fuel and burner design | Usually supplemental heat for a small room or localized area | No chimney is generally required, but the room must have adequate ventilation | Real flame with visible movement and no electrical flame simulation | Requires replacement fuel cans; fuel consumption and burn time vary by product | Approved fuel containers, spill-resistant burner, secure flame enclosure, stable stand, and a safe extinguishing method | Users who want a real flame without installing a permanent gas fireplace | Medium |
| Ventless Gas Fireplace | Commonly about 20,000–40,000 BTU/h Model limits vary | Can heat a larger area than most electric units, subject to local regulations and room size | No chimney may be required, but combustion releases moisture and gases into the room; ventilation and code compliance are essential | Real gas flame with ceramic logs or other decorative media | Uses natural gas or propane; fuel cost depends on local utility rates and usage | Oxygen-depletion sensor, automatic gas shutoff, flame-failure protection, carbon-monoxide alarms, and professional installation | Homes permitted by local codes that need stronger supplemental heat | Medium |
| Vented Gas Fireplace | Commonly about 25,000–40,000 BTU/h Model limits vary | Suitable for supplemental heating, with performance affected by vent design and installation | Requires an approved direct-vent or chimney-style venting system and professional installation | Real gas flame with realistic logs or decorative media | Uses natural gas or propane; some heat is lost through the venting system | Sealed combustion where applicable, flame-failure protection, automatic shutoff, tempered glass, and carbon-monoxide alarms | Permanent installations where realistic flames and code-compliant venting are acceptable | Medium |
| Decorative Electric Fireplace Without Heat | 0 BTU/h heating output | Provides no space heating | No ventilation, fuel, or special installation required | LED-generated flame effect only | Very low electricity use compared with heated fireplace models | Low-temperature operation, automatic shutoff, certified electrical components, and a stable TV stand | Warm climates, seasonal decoration, or households that do not need additional heat | Very High |
