Buying Guide: Key Purchase Considerations
Outdoor and worksite heating requires evaluating space size, safety, and fuel logistics. Start by calculating BTU needs based on space and insulation. Higher BTU units heat faster but burn more fuel. Consider hose length and regulator compatibility to match your propane tank. CSA and safety certifications add assurance in environments with workers or family around. For enclosed spaces, ensure proper ventilation to prevent carbon monoxide buildup. Noise levels may matter for indoor use; some models advertise quieter operation than others.
