Buying Guide
What size space should I heat? Start with the square footage and ceiling height. Higher BTUs are needed for larger or higher-ceiling spaces. Consider insulation quality and any drafts.
Ceiling-mounted vs portable: Ceiling units save floor space and work best in dedicated workshops with mounting options. Portable heaters offer flexibility but require careful placement to avoid tripping hazards and ensure proper ventilation.
Safety features to look for: oxygen depletion sensors, tip-over switches, automatic shutoffs, and CSA or UL safety certification. Always follow manufacturer installation instructions for gas supply and ventilation.
Ventilation and oxygen: propane heaters emit combustion byproducts. Operate in well-ventilated areas or use units designed for indoor use with proper venting as recommended by the manufacturer.
Fuel considerations: propane is convenient and widely available. Check for compatibility with existing propane supply lines or tanks and the availability of service in your area.
Installation and maintenance: some units require ceiling brackets or professional mounting. Regular inspection of hoses and regulators is advised to maintain safe operation.
