Buying Guide: Key Purchase Considerations
- Room size and BTU capacity: Match the heater’s BTU rating to your room size. Larger spaces require higher BTUs, while smaller spaces benefit from lower ratings to avoid overheating.

- Fuel type and efficiency: Natural gas units typically offer consistent cost and supply. Check efficiency ratings and modulating control to minimize waste while maintaining comfort.
- Noise and comfort: Sealed burn systems and modern burners reduce noise. Consider units with quiet operation if the heater will be in living areas or bedrooms.
