Buying Guide
What should you consider when choosing a propane heater for a boat?
- Heat requirement: Calculate the cabin volume to pick BTU capacity. Boats with tighter layouts may be comfortable with 4,000–9,000 BTU depending on insulation and ventilation.
- Ventilation and safety: Look for oxygen depletion sensors, tip-over protection, and auto shut-off features. Ensure proper ventilation and follow marine safety guidelines.
- Fuel and power: Radiant propane heaters typically need no electricity, which is advantageous aboard. Consider availability of propane canisters and tank sizes for your travel plans.
- Ventilation type: Direct-vent models can be preferable on boats, reducing backdraft and improving efficiency, but may require installation considerations.
- Portability vs. permanence: Choose a compact, lightweight model for easy storage, or a slightly larger unit for steady warmth in a main cabin.
- Durability and materials: Stainless steel and robust casings help resist marine corrosion and humidity.
