Buying Guide: Key Considerations For Your 20 Inch Electric Fireplace Insert
What matters most when selecting a 20 inch electric fireplace insert? Focus on size compatibility, heat output, flame realism, control options, and installation flexibility.
- Size fit: Confirm your fireplace recess or wall opening accommodates a 20″ insert with adequate clearance for ventilation and wiring. Some 18″ models can visually fit but check dimensions and mounting options.
- Heat output: Look for two heat settings or adjustable wattage (750W/1500W) to tailor warmth for your space. Higher wattage improves room heating ability, while lower wattage saves energy.
- Flame realism: Advanced flame technology and realistic logs enhance ambience. If looks are paramount, prioritize models with realistic glow and lifelike flames.
- Controls: Remote controls and thermostat/timer functions offer convenience and energy management. Decide between manual or smart controls based on lifestyle.
- Installation type: Decide between built-in, recessed, or wall-mount installations. Some inserts require a separate surround or mantel for finished aesthetics.
- Safety features: Overheat protection, automatic shutoff timers, and stable bases reduce risk in busy living spaces or homes with children and pets.
- Durability and warranty: Consider build quality, especially for premium-looking inserts like the Revillusion. Review warranty terms for parts and service.
Frequently Asked Questions
- Do 20 inch electric fireplace inserts require a vented chimney?
No. They run on electricity and do not require venting. They produce heat via internal elements and can be used with or without a decorative surround. - Can I install these inserts myself?
Many inserts are designed for DIY installation in existing fireplace recesses or walls, but follow the manufacturer’s instructions. Some setups may require professional help for electrical connections. - Will the flame effect work without heat?
Most inserts allow flame effects to operate with heater off, enabling ambiance-only use year-round. - What is the best choice for a bedroom?
Look for models with quiet operation, energy-efficient heat settings, and safety features like cool-touch surfaces and timers to avoid overheating at night. - How do I choose between a realistic log set and a flame-only insert?
If ambience is the priority, a log-style flame adds realism. For modern aesthetics, pick a flame-only design with vivid colors and adjustable brightness. - Are these units safe around kids and pets?
Choose inserts with overheat protection and stable bases. Place heaters on a nonflammable surface and keep away from direct contact with walls or fabrics.
