Buying Guide: Key Purchase Considerations
- Vent-free versus vented: Vent-free units save on ducting and installation complexity but require good room ventilation and carbon monoxide safety awareness. Vented options often exhaust outdoors, reducing indoor heat load.
- BTU and room size: Match BTU to the space. Larger spaces may need 20,000–30,000 BTU or more, while smaller rooms can be comfortable with 10,000–20,000 BTU.
- Blower capability: Units paired with a blower improve air circulation and even heat distribution. Check whether a blower is included or sold separately.
- Thermostat and controls: Built-in thermostats help maintain consistent temperatures. Consider manual controls for simplicity versus digital controls for precision.
- Safety features: Oxygen depletion sensors, automatic shut-off, and tip-over switches add protection in indoor applications.
- Installation options: Wall mounting, floor placement, and the availability of mounting hardware influence installation time and flexibility.
- Fuel type and fuel conversion: Ensure compatibility with natural gas supply and check whether any conversion kits are required or permitted by local codes.
- Operating costs: Compare BTU efficiency and expected gas consumption. Consider the long-term cost of running a heater in the targeted space.
- Warranty and support: Review warranty duration and access to service if components such as blowers or burners need maintenance.
