This Universal 12V Low Profile Auxiliary Heater Is Built For Cab And Vehicle Applications Where A High Airflow, Low-Profile Unit Is Required. It Includes An Installation Kit For Many Vehicle Types.

• Output: Rated 13,000 BTU equivalent for rapid cabin warm-up (claims vary by insulation).
• Compatibility: Designed For Tractors, Trucks, Buses, Vans, Cars, UTVs — marketed as a universal cab heater.
• Installation: Comes with a kit; requires 12V electrical supply and a mounting location with ducting or louvers.

This Type Of Heater Is A Common Choice When A high-flow, electrically powered heater is preferred over combustion-based units. Check your van’s alternator and battery capacity to ensure the unit’s current draw is sustainable while running or during start-up.

Mr. Heater MH4GC 4000 BTU

Check Price on Amazon

The Mr. Heater MH4GC Is A portable propane radiant heater initially designed for golf carts but commonly used for small, ventilated spaces. It’s wind-resistant and includes safety features such as an oxygen depletion sensor (ODS) and tip-over switch.

• Heating: 4,000 BTU radiant heat suitable for spot heating in small van interiors or outdoor shelter spaces.
• Runtime: Up To Approximately 5.5 Hours Depending On Propane Tank Size.
• Safety: ODS and tip-over switch reduce risks when used with appropriate ventilation and safety procedures.
• Altitude: Designed To Operate Up To 7,000 Feet.

Portable propane heaters Provide fast spot heat without electrical demands but require adherence to ventilation, fuel storage, and carbon monoxide safety considerations. Confirm local regulations and installation needs before using inside an enclosed van.

Caframo True North Electric Heater

The Caframo True North Is A compact, quiet electric heater with adjustable thermostat, multiple heat/fan settings, and an anti-freeze function that engages at low temperatures. Its solid steel housing is low-profile and suitable for small living spaces.

• Controls: Three heat and two fan settings plus an anti-freeze mode to prevent freezing during storage.
• Design: Low profile and quiet operation; intended for indoor or sheltered use.
• Electrical: Requires AC power; in van use it demands an inverter and sufficient battery/inverter capacity.

Electric Heaters Like This Provide clean, quiet heat without combustion. For full-time van living, confirm inverter size and battery capacity; pairing with shore power or a robust lithium system is common for practical use.

Buying Guide: Choosing The Best Heater For Your Van

Selecting a van heater requires evaluating fuel source, heat output, installation complexity, safety, and operational cost. Below are the primary considerations with comparison perspectives to help you decide.

Fuel Type And Power Source

Common options include diesel parking heaters, gasoline bunk heaters, propane portable units, and electric (AC) heaters. Each has trade-offs:

• Diesel Heaters: Use vehicle fuel tank, provide continuous combustion heat, good for long-term or high-output needs; require exhaust routing and fuel line hookup.
• Gasoline Heaters: Similar to diesel units but fueled by gasoline; typically compact with low electrical draw, suitable when vehicle runs gasoline.
• Propane Heaters: Portable and powerful per BTU, but need ventilation and CO monitoring; great for occasional spot heating.
• Electric Heaters: Clean and quiet; require shore power or a high-capacity inverter and batteries for off-grid use.

Heat Output And Coverage

Match heater output to van volume and insulation level. Higher BTU/kW units heat larger, less-insulated vans faster. Compact units are efficient for well-insulated, small camper conversions.

Installation Complexity And Space

Hardwired heaters like diesel or gasoline units need mounting space, exhaust exits, and fuel routing. Auxiliary 12V units and electric heaters are easier to install but may demand significant electrical capacity. Portable propane units require secure mounting and safe storage for fuel cylinders.

Power Draw And Energy Management

For 12V electrical heaters, verify alternator and battery capability. Diesel/gasoline heaters still draw electrical power for pumps/fans and need a suitable 12V source. For electric AC heaters, estimate inverter size and battery autonomy before committing.

Safety And Ventilation

Combustion heaters require proper exhaust routing and ventilation to avoid CO build-up. Use certified CO alarms, follow manufacturer clearances, and consider ODS-equipped propane units. Regular maintenance is essential for safe operation.

Altitude And Climate Considerations

If you travel to high elevations, choose units with altitude compensation or proven high-altitude performance. Outdoor temperature extremes affect heater selection — combustion heaters generally handle very cold climates better than small PTC electric elements.

Noisy Versus Quiet Operation

Electric fan heaters and some forced-air combustion units produce fan noise. If you require very quiet sleeping environments, prioritize models marketed for low noise or consider radiant/infrared options for spot heat.

Maintenance, Parts, And Support

Check for available replacement parts (fuel pumps, glow plugs, controllers) and warranty length. Choose brands with documented installation guides and community or dealer support if you plan DIY installation.

Cost Of Operation And Fuel Availability

Operational cost varies by fuel price and efficiency. Diesel heaters tend to be cost-effective where diesel is available. Propane is convenient but requires cylinder refills. Electric heating can be inexpensive on shore power but costly off-grid unless renewable charging is available.

Installation Options And Professional Help

Complex combustion heaters usually require professional installation or thorough adherence to manufacturer instructions. Simpler electric or portable units can be DIY-installed, but ensure secure mounting and correct wiring.

Which Heater Fits Which Van Setup?

• Full-Time Off-Grid Van Life: Diesel parking heater or efficient gasoline bunk heater for continuous, low-electrical draw heat.
• Part-Time / Weekend Camping: Portable propane heater or electric heater with shore power works well.
• Well-Insulated Compact Vans: Smaller electric or low-power 12V heaters can maintain comfortable temps with lower draw.
• High-Altitude Travel: Choose heaters with automatic altitude compensation or models rated for high elevations.
