Diesel Heater Built-In Compass
2027 Upgraded Version! Features a top compass for quick directional reference during off-road and overland trips. Helps you easily check your surroundings, set up camp, and position the heater for optimal airflow in remote environments.Product Features:
6L Large Fuel Tank & High Fuel-EfficiencyHigh-efficiency combustion consumes as little as 0.03 gal/h(0.13 L/h) (Level 1) to 0.09 gal/h(0.35 L/h) (Level 10). Paired with a 1.6 gal (6L) fuel tank, it delivers up to 46 hours of runtime at Level 1, 28 hours at Level 5, and 17 hours at Level 10. Running an 8-hour night on low heat uses only ~0.26 gal(0.98 L) of diesel—delivering maximum cost efficiency for off-grid campers, truckers, and vanlifers.
±2°C Precision Control Constant Temp
An optimized temperature algorithm tightens the auto start/stop threshold to ±2°C for extreme sensitivity to subtle ambient changes. By adjusting continuously in compact spaces, it prevents drastic temperature swings and creates a stable interior micro-climate, ensuring uninterrupted overnight comfort without manual panel tweaks in the middle of the night.
IPX4 All-Weather Waterproof Protection
The entire unit has passed strict lab testing and earned the internationally recognized IPX4 waterproof rating, with both the main body and wiring treated for water resistance. It repels rain, mud, and road spray from all directions while fully protecting the internal motherboard and motor. Built for camping in the rain, parked in snow, or driving muddy off-road trails.
Adaptive High-Altitude Mode
The intelligent control system automatically detects elevation and adjusts fuel injection based on ambient oxygen levels. By maintaining clean, stable combustion in high-altitude environments, it prevents flameouts and black smoke. Delivers continuous, reliable heat without loss of efficiency across alpine valleys and mountain passes.
Leak-Proof Fuel System
Equipped with an upgraded two-way pressure-relief valve fuel cap that balances internal tank pressure during travel. Prevents fuel overflow, tank collapse, and leakage caused by severe off-road vibration, keeping your cabin free from diesel fumes and fire hazards. Compact and portable for effortless setup, moving, and storage.

FAQs About TB MAX Diesel Heater
1. What makes the TB MAX Diesel Heater different from other portable diesel heaters?
The TB MAX features a large 7.5L fuel tank for up to 62.5 hours of continuous heat, an upgraded silent fuel pump, and precise wireless temperature control. Ideal for vans, RVs, cabins, or tents.
2. How fast does the TB MAX heat up?
The heater provides rapid warmth in about 3 minutes thanks to its advanced aluminum body and optimized combustion system, giving reliable heat on-demand for camping, off-grid cabins, or mobile use.
3. Can the TB MAX be used at high altitudes?
Yes. The TB MAX automatically adjusts combustion for reliable performance up to 18,000 ft (5.5 km), making it perfect for high-altitude adventures or mountainous locations.
4. How does the wireless remote work?
The wireless remote doubles as an indoor thermostat, sensing the actual room temperature for precise control. It allows you to manage heat safely from inside your van, cabin, or tent without placing the main unit indoors.
5. Is the CO sensor integrated?
Yes. The CO sensor is built into the wireless remote. Set custom alarm and shutdown thresholds (200–500 ppm recommended) via the mobile app.
The heater sounds an alarm at the threshold and shuts off automatically at the shutdown level (error code E11). Smoke or other indoor sources may trigger the sensor—after checking, the heater can be restarted normally.
6. How quiet is the TB MAX?
The upgraded silent fuel pump eliminates ticking sounds, keeping noise levels low. The primary sound comes from the air duct outlet (~65 dB).
7. Where should the TB MAX not be used?
Do not operate near flammable vapors or dust, such as fuel depots, gas stations, or lumber yards. Keep away from fuel tanks, compressors, clothing, and fire extinguishers to prevent fire hazards.
8. How should I install the exhaust and ventilation system?
Ensure all air inlets and exhaust pipes are clear. The metal exhaust pipe must vent outdoors to prevent carbon monoxide buildup. Avoid using the heater in sealed or poorly ventilated areas.
9. Is the wireless remote compatible with other Hcalory heaters?
Yes. The wireless temperature sensing remote control applicable for TB MAX, TB2S, TB2S+, and TC2S models.
