Buying Guide: Key Considerations For Infrared Gas Wall Heaters
- Fuel source: Decide between natural gas-only units and ventless options that may require gas lines or venting considerations.
- BTU and space coverage: Match BTU to room size. Higher BTU suits larger rooms; smaller rooms may need lower BTU to avoid overheating.
- Controls: Choose manual, thermostat, or programmable options based on how you want to regulate heat and energy use.
- Installation style: Wall-mounted versus floor-based with base feet affects room layout and clearance requirements.
- Safety features: Look for oxygen depletion sensors and automatic shut-off for safe operation in occupied spaces.
- Ventilation and emissions: Ventless designs simplify installation but ensure adequate ventilation where required by local codes.
