Buying Guide: Key Purchase Considerations
- Fuel source and availability: Confirm natural gas versus propane when evaluating installation and venting requirements. Ventless units require adequate clearance for safety and indoor air quality considerations.
- Ventilation and exhaust: For vented units, verify whether vertical or horizontal venting is feasible given your outdoor structure. Ventless configurations mandate proper ventilation in adjacent indoor spaces.
- Space and coverage: Match BTU output to the intended area. Higher BTU units cover larger spaces but may require more robust mounting and electrical or gas line work.
- Mounting and safety: Ensure mounting hardware, brackets, and clearance meet manufacturer specs. Keep ignition units away from combustibles and maintain required clearances from floor and walls.
- Maintenance and accessories: Check for thermostat compatibility, gas regulator requirements, and service intervals. Some models exclude thermostat and regulator; plan accordingly.
- Durability and weather resistance: Outdoor units should be corrosion-resistant and rated for outdoor exposure. Consider units with protective finishes and weatherproof components.
- Energy efficiency: Hydronic or hot-water-linked systems can offer energy savings in some installations, but installation complexity increases. Compare overall running costs and system compatibility.
- Local codes and safety: Always verify compliance with local building codes, outdoor heating regulations, and gas line installation standards before purchase and installation.
