Buying Guide: Key Considerations
- Space coverage: Verify the heater’s rated heating area (ft²) and compare with your vehicle, garage, or tent size.
- Power supply: Most units operate on 12V–24V DC; some offer 110V option via transformer. Confirm compatibility with your setup.
- Altitude performance: If you use high elevations, choose models with automatic altitude compensation (up to 18,045 ft).
- Control method: App, remote, or built-in LCD display—pick the method that fits your setup and convenience.
- Safety features: Look for CO sensors, overheat protection, insulated exhaust, and fuel leak safeguards.
- Fuel efficiency: Consider tank size and fuel consumption per hour to estimate runtime between fills.
- Installation and portability: Some models are truly all-in-one with no installation, while others need ducting or mounting; choose based on space and ventilation needs.
