Buying Guide
- Space size matters: Match BTU output to the room size. Smaller rooms (up to 300 sq. ft.) typically do well with 10,000 BTU units; larger spaces may need 20,000–30,000 BTU units.
- Thermostat control: A built-in thermostat helps maintain comfort by cycling the burner on and off automatically, reducing propane usage and preventing overheating.
- Ventilation and safety: Vent-free models can be used without a chimney, but ensure proper ventilation and follow clearance guidelines. Consider models with an Oxygen Depletion Sensor (ODS) for added safety.
- Mounting and placement: Decide between wall-mountable units or floor models with base feet. Infrared plaques offer a slim profile, while traditional blue-flame designs emphasize robust heat output.
- Outdoor readiness: For ice houses or outdoor shelters, look for heaters designed to operate in cold conditions and with compatible hoses/regulators for propane cylinders.
- Fuel accessibility: All options rely on liquid propane. Confirm cylinder size, hose length, and regulator compatibility for your space.
