Buying Guide
- What space are you heating? Choose BTU ranges that match room size. For example, 30,000 BTU units cover about 1,000 sq ft, while 10,000 BTU units fit smaller spaces up to 500 sq ft.
- Do you need a thermostat? Thermostat-controlled models offer consistent comfort and energy savings by maintaining a set temperature.
- Fuel type and flexibility: Natural gas units require a gas supply and venting considerations. Dual-fuel models provide propane compatibility as a backup.
- Ventless vs vented: Ventless heaters simplify installation but require proper room ventilation per code. Vent-free radiants and blue flame designs differ in heat distribution and feel.
- Installation style: Wall-mounted infrared or blue flame plaque units save floor space; floor-base models suit portable needs. Ceiling-mounted options exist for larger units; verify clearance and mounting hardware.
- Safety considerations: Ensure carbon monoxide concerns are addressed with proper detectors and venting when required. Maintain safe clearances from walls, furniture, and drapes.
