Diesel Heater Large Fuel Tank Capacity

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.

Product Features:

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.

TB MAX Diesel Heater Toolbox, 7.5L CO Alarm Last Up to 62.5 hrs

My First Diesel Heater!!!

I took my time and researched the diesel heaters on the market and the TB MAX Diesel Heater Toolbox, 7.5L with CO Alarm and Phone App is definitely a Game Changer!

This diesel heater holds more fuel than their counterparts/competitors! I especially appreciate having three ways to monitor and check on the progress/functions of my heater via the App, Keyed chain remote controlled wireless temperature sensor with a awesome safety CO feature, and the LCD panel which comes with an LCD Extension Cord that can reach inside your tent!

This diesel unit is creatively designed to keep from being accidentally tipped over by the way it is built. It is also very quiet and soothing when it is on without the annoying ticking sound! I also liked the carrying handles on this heater. This heater gives you dry heat that will not create moisture in your tent!

The only thing I wish was a little better is the heating duck which has a shorter hose than what I need. A quick trip to the hardware store can easily solve that problem. What came with the unit was sufficient but depending on your needs, some sites may require a longer heating duct hose.

Overall I am so happy with this unit! I have not had a chance to test it out on an actual camping trip. So far, I've tested it out in my garage while I worked and it is great! Make sure you vent properly and get a backup CO for safety redundancy.

If you are in the market for a cost effective diesel heater with a huge diesel tank, safety features, and gadgets to monitor the heater's performance, than this heater is an exceptional choice. I also was given a great discount in Dec 2025, AND their customer service was very responsive to all my emails in a timely manner.

A great heater

It was a pleasure to set up this diesel heater. The heater is very hot and the noise is very low.
Love the remote and the app for controlling the heaters functions and information.

Great heater for Alaska winters in a Truck Camper

Best diesel heater around to heat my truck camper during Alaska cold winter temps on the road. Runs hot and uses very little power on my lithium power stations. No better heat source around. Highly recommend this diesel heater.
