Buying Guide
Direct vent and vented heaters are chosen for safety, efficiency, and space utilization. Consider these factors when deciding which model to buy.
- Room size and heating needs: Match BTU output to the area you plan to heat. Undersized units struggle to maintain comfort; oversized units may waste fuel and shorten component life.
- Ventilation and installation: Direct vent models require proper wall venting and clearance. Ensure your space allows safe vent routing and outdoor exhaust.
- Fuel type: Propane units require a reliable LP supply and proper storage; kerosene units work where electricity is unreliable but demand good ventilation and indoor fuel handling.
- Ignition and safety features: Look for sealed burn systems, safety pilots, regulators, and automatic shutoffs to reduce risk and improve reliability.
- Portability vs. fixed installation: Wall-mounted units save floor space; portable kerosene heaters provide flexibility during emergencies or power outages.
- Maintenance considerations: Regularly inspect burners, regulators, and vent paths. Periodic wick and fuel system checks are needed for kerosene models.
