What to consider before buying

When choosing an RV heater, consider your power source availability (propane vs. electric vs. catalytic), the size of your RV, and whether you need portability. For boondocking, catalytic or propane heaters are ideal. For larger RVs with shore power, a direct vent furnace is more efficient. Always check safety features like oxygen depletion sensors and ensure proper ventilation.
