Buying Guide
What to consider when choosing a 47000 BTU patio heater:
- Heat source: Propane vs. electric. Choose propane for true outdoor warmth and mobility; choose electric infrared for gas-free operation and quick personal warmth.
- Space and coverage: Match BTU to space. Higher BTU is better for larger areas; smaller patios can comfortably use 47000 BTU models with proper airflow.
- Mobility vs. permanence: Wheels and stands add flexibility; fixed, tabletop designs save space but are less movable.
- Safety features: Look for tip-over protection, flame-out shutoff, and anti-tilt sensors. CSA/ETL certifications can indicate compliance with safety standards.
- Fuel considerations: Propane availability and cylinder size affect run time. Plan for fuel needs during extended outdoor use.
- Maintenance: Stainless steel burners withstand weather; follow manufacturer guidelines for cleaning and storage to extend life.
- Warranty and support: Check warranty terms and whether replacement parts are readily available.
