Installation Notes: Although described as all-in-one, safe exhaust routing and placement away from tent fabric remains required. Automatic altitude compensation simplifies operation across variable campsites.
BreAro All In One 8KW Diesel Air Heater
Rapid Heating And Controls: The BreAro claims quick heat delivery using a sandblasted aluminum heat exchanger and an intelligent LCD with remote control. Time on/off and thermostatic control options support scheduled warm-up for RTT nights.
Safety Features: Includes intelligent sensors to prevent dry-run and overheating protection at specified thresholds. Precision fuel pump and ceramic ignition are specified to promote cleaner combustion and lower emissions.
Endurance And Consumption: A 5L tank and stated consumption ranges suggest multiple hours of run time, relevant to overnight use in a roof top tent. The unit emphasizes low emissions and a steady temperature output for sleeping comfort.
RTT Use: The BreAro offers features aligned with intermittent overnight heating—set timers and thermostatic control can avoid unnecessary runtime while maintaining comfort in small, insulated RTT spaces.
LF Bros 5KW Diesel Heater All-In-One
Lower Power Option: The LF Bros offers a 5KW output versus the 8KW units in this list, making it suitable when lower heat output is acceptable or when conserving fuel is a priority for RTT campers in milder conditions.
Versatile Power Input: Comes with a 110V transformer plus 12V/24V support, enabling operation from campsite shore power or vehicle battery systems. This flexibility helps campers who alternate between drive-and-camp and basecamp setups.
Use Cases And Controls: The model includes remote control and LCD, a typical set of conveniences for scheduled pre-warm cycles. Manufacturer specs list a wide working temperature range and a fuel consumption band to estimate run time.
RTT Suitability: As a lower-output heater with plug-ready capability, this unit may be appropriate for larger tents with better insulation or for campers who plan to use supplemental insulation and lower target interior temperatures.
Buying Guide: Choosing A Diesel Heater For A Roof Top Tent
This buying guide highlights practical purchase considerations for RTT users, presenting multiple comparison angles such as safety, portability, power, and fuel economy.
Safety And Ventilation
- CO Detection: Choose heaters with integrated CO alarms or ensure you add an independent CO detector. In enclosed or semi-enclosed tent spaces, carbon monoxide risk is a primary safety concern.
- Exhaust Routing: All diesel heaters require safe exhaust piping routed away from fabric and sleeping areas. Confirm clearances and use heat shields where specified.
- Fuel System Security: Leak-proof caps and secure tank placement reduce spill risk when parked on uneven ground or while driving between campsites.
Portability And Installation
- All-In-One vs. Split Systems: All-in-one units combine burner, fan, and tank—easier to set up but require careful placement near the tent. Split systems offer more flexible installation but are heavier to install.
- Toolbox / Portable Designs: Models with handles and compact housings (toolbox style) make short-term RTT use and storage simpler.
- Mounting And Movement: Consider how often you’ll move the unit. For frequent relocations, prioritize compact, self-contained heaters with secure latches and integrated tanks.
Power Source And Consumption
- 12V/24V Compatibility: For vehicle-powered operation, 12V or 24V DC compatibility is essential. Confirm your vehicle’s electrical capacity and alternator output for continuous overnight use.
- AC Option: Models with 110/220V capability are useful for campsite shore power or when using an inverter but add weight and complexity.
- Fuel Efficiency: Compare listed fuel consumption (L/h or gal/h) and tank capacity to estimate runtime. Lower output heaters consume less fuel but may provide insufficient heat in cold conditions.
Heat Output, Size, And Climate
- Match Heat Output To Tent Volume: RTT interiors are relatively small—5KW may suffice in mild conditions, while 8KW provides faster warm-up and more headroom in colder climates.
- Insulation And Window Coverage: Better tent insulation reduces required heater output. Use thermal liners and close vents to retain heat efficiently.
- Altitude Effects: If camping at high elevations, prefer heaters with automatic altitude compensation or manually adjustable settings to maintain combustion stability.
Controls, Monitoring, And Convenience
- Remote And App Control: Remote controls and Bluetooth/app features allow preheating before entering the tent—useful for timed warm-up and energy savings.
- Thermostatic And Timer Functions: Thermostats and timers maintain comfort without continuous manual intervention, extending fuel economy during overnight use.
- Diagnostics And LCDs: Visual fault codes and LCDs simplify troubleshooting in the field and help verify proper operation before sleeping in the RTT.
Noise, Emissions, And Comfort
- Low Noise Operation: Check specified decibel ranges where available if sleeping near the heater is planned.
- Emission Controls: Precision fuel pumps and ceramic ignition improve combustion; models that advertise reduced exhaust temperature and smoke reduce impact on tent interiors.
- Airflow Management: Consider ducting options and directional vents to distribute warm air inside the tent without blowing directly on sleepers.
Comparison Perspectives
- Safety-Focused Users: Prioritize CO alarm integration, overheat protection, and leak-proof fuel systems.
- High-Altitude Campers: Select units with automatic altitude compensation to maintain reliable combustion and avoid hard-starts or increased emissions.
- Minimalists And Frequent Movers: Favor compact, toolbox-style models with handles and integrated tanks for quick stowage and transport.
- Basecamp Campers With Shore Power: Consider units offering 110V/220V operation for reduced battery drain and extended runtime when electricity is available.
When selecting a diesel heater for an RTT, weigh safety and exhaust management foremost, then match power, portability, and fuel economy to your typical campsite and climate. Always follow manufacturer installation and ventilation guidelines to ensure safe operation in and around roof top tents.
