Large 7.5L fuel tank provides up to 62.5 hours of continuous heat on a single fill. Wireless remote doubles as an indoor thermostat, sensing the actual room temperature for precise control. Upgraded silent fuel pump eliminates the irritating ticking sounds found in traditional heaters. Includes 1.5m extension cable for indoor control panel mounting. Fits for vans, cabins, or tents.
True Remote Temperature Control
The wireless remote doubles as an indoor thermostat, sensing the actual room temperature for precise control. Place the heater outside your tent, van, or cabin and simply run the heat duct inside. This allows for a safer, quieter, and more space-efficient setup, as the main unit no longer needs to occupy your living area. Enjoy perfectly automated comfort based on the temperature where you are, not at the heater's location.
Rapid 3-Minute Warmth
Experience on-demand heat in just three minutes, even in sub-zero conditions. Our advanced aluminum body and optimized combustion system work together to deliver powerful, consistent warmth the moment you need it. This swift response is complemented by 36% better fuel efficiency, significantly saving on operating costs without sacrificing performance.
Up To 62.5 Hours With Minimum Setting
Designed for long-lasting adventures, the large 7.5L fuel tank provides up to 62.5 hours of continuous heat on a single fill. This exceptional duration, combined with superior fuel efficiency, means fewer refills and uninterrupted warmth for entire weekends or off-grid excursions. Rely on steady comfort in even the most frigid climates.
Quiet Operation with Silent Fuel Pump
The air duct outlet remains the primary noise source (65 dB, equivalent to normal conversation), but our upgraded silent fuel pump eliminates the irritating ticking sounds found in traditional heaters. Perfect for uninterrupted sleep in vans, cabins, or tents.
All-Terrain Adaptive Performance
Never lose efficiency at high altitudes. Our heater auto-adjusts its combustion for optimal performance up to 18,000 feet (5.5km), ensuring full heat output and fuel economy in mountainous terrain. Perfect for high-altitude climb or at a remote alpine worksite.
⚠️Notice: About the Carbon Monoxide Sensor
The CO sensor is integrated into the wireless remote control. You can set custom alarm and shutdown thresholds (recommended: 200–500 ppm) via the mobile app. When CO levels reach the alarm threshold, a beep sounds; at the shutdown threshold, the heater automatically powers off and displays error code E11.
Smoke or other indoor sources (such as fireplaces or stoves) may also trigger the sensor. After checking the source, you can restart the heater normally.

1. Can I use the TB2 diesel heater during warmer months like spring or summer?
Yes. The TB2 features a ventilation mode, allowing you to circulate air without heat—perfect for spring camping, van life, or mild weather RV use.
2. What power options does this portable diesel heater support?
It supports both 12V/24V DC and 110V/220V AC power, making it highly versatile for use in RVs, vans, trucks, cabins, or garages.
3. How fuel-efficient is the TB2 diesel heater for off-grid use?
Very efficient. The fuel consumption ranges from 0.036 to 0.1 gal/h, and the 6L built-in tank provides up to 32% longer runtime than previous models—ideal for overnight heating without refueling.
4. Is this heater suitable for high-altitude areas?
Yes. With Plateau Mode support for up to 20,000ft elevation, the TB2 ensures stable heating and complete combustion, making it ideal for mountain camping or ski trips.
5. How do I control the TB2 heater remotely?
The TB2 offers Bluetooth app control, letting you adjust temperature, set timers, or activate altitude mode directly from your smartphone. It also includes a remote control and an LCD panel for flexible operation.
6. Is the TB2 easy to install and move around?
Yes. Its toolbox-style design is compact and all-in-one, making it portable and DIY-friendly for camper van setups, truck cabins, or home garages.
7. Can the TB2 heater warm multiple areas in my RV or van?
Yes. You can pair the TB2 diesel heater with an optional 90mm Y Branch Air Ducting Connector to direct warm airflow into multiple zones of your RV, camper, or van. This add-on makes it easy to create a multi-room heating setup, improving comfort and efficiency for different areas.
8. Can I use the TB2 Diesel Heater on a boat?
Yes, you can — but please use with care. TB2 is a portable heater and not specifically designed for permanent placement in one fixed location. If you plan to use it on a boat, please consider the following:
(1) Light rocking and vibration are acceptable, but ensure the heater remains upright and stable. Movement could loosen the air or exhaust pipes, so check them regularly.
(2) The unit must remain upright to avoid fuel leakage or malfunction.
(3) There are no built-in mounting features for securing the unit to a boat. The TB2 was not designed with mounting holes or brackets, so if you need to fix it in place, you’ll need to create a custom solution.
Notes: TB2 is intended as a portable heater. Using it on a boat is possible, but requires extra care in placement and stabilization. Many of our customers have successfully used the TB2 in boats, RVs, and off-grid cabins — make sure to keep it stable.
Shipping to Slovakia was incredibly fast — even faster than our domestic shipping! :D After using a diesel heater from another brand, this one is a huge upgrade. I absolutely love it. I use it for my rooftop tent, and the quiet operation is a big advantage, especially at campsites where I don’t want to disturb others.
The install was straightforward, and I like that the housing feels weatherproof. The noise is minimal, just a low hum, way quieter than my last diesel heater. Only downside so far is the unit is a bit heavier than I expected at almost 29 lbs. But once it's set, it's rock solid.
I tested for the new TB MAX and took it on a 4-day road trip in my 24ft Class C RV. The heater handled it like a champ.
Installation was straightforward. The included diagrams and harness made sense once I laid everything out. Took me about 20 minutes start to finish, and I mounted the control panel inside using the 5ft extension cord. The unit itself is heavy (almost 29 lbs), but it feels very solid and well-built.
The heater kept the RV steady around 70-72°F. I tested the run time, and the 7.5L diesel tank lasted me just about 60 hours total, which matches Hcalory's claim. I didn't have to worry about refilling mid-trip, which is a big deal compared to smaller heaters I've used.
The upgraded 90mm duct does help. There's a gentle whoosh sound, but no annoying rattle. The fuel pump does tick, but it's faint and blends into the background after a few minutes.
The remote CO alarm is a nice addition. I tested it by placing it near my garage while running the heater indoors for a few hours. The alarm went off exactly as it should. For me, that's peace of mind with the kids sleeping in the RV.
Overall: This is the first diesel heater I've used that I trust for longer, off-grid trips. It runs efficiently, quietly, and safely. If you do a lot of RV travel, the large tank alone makes it worth it.
Got to test the TB MAX this month, and I'm impressed. I used it during a rainy weekend campout, and the sealed housing really held up. The remote with the CO alarm is a great safety feature, and I tested the alarm just to be sure it works. Ran it about 9 hours straight one night, fuel consumption was very low. For anyone who wants long-lasting heat without babysitting the tank, this heater nails it.
As part of the Hcalory testing program, I used the TB MAX in my 12x18 ft off-grid cabin in Wyoming.
Setup & Build: The weather-resistant housing really stood out to me. It rained for half a day, and I had the heater running outside with ducting into the cabin no issues with moisture, no sputtering. The aluminum body feels sturdy and built for rugged use.
Altitude Mode: Took it up to 9,200 ft on a camping trip. The auto altitude adjustment worked perfectly. I didn't have to tweak anything, and it kept a 6x12 trailer at 75°F all night.
Noise & Comfort: It's quieter than expected. You hear the hum and pump ticking, but not enough to keep me awake. Honestly, the silence in the mountains was louder than the heater.
Downside: The app paired fine with my Android, but my buddy struggled a bit with iOS at first. Once connected, though, it works reliably.
Final Thoughts: If you're looking for something for cabins or mountain camping, this is a serious upgrade from smaller 5L heaters. Long runtime and altitude adjustment make it worth it.
