When you’re traveling in the depths of winter, it is necessary to prepare a diesel heater in your RV. Believe you don’t want to
When you’re traveling in the depths of winter, there’s nothing more unpleasant than trembling all night or awakening to a cabin that feels like an icebox. Throughout the years, I’ve evaluated more diesel heaters than I can remember— but Hcalory diesel heater impresses me with their unmatched value and consistent improvements.
This year, they’ve released a new collection for 2025, and I’ve chosen my three favorites. Let’s see how they are.

My Top 3 Hcalory Diesel Heaters for 2025
From Hcalory’s 2025 collection, I’ve selected three particular models that I think are ideal for various kinds of drivers. Hcalory HBS2, which I selected due to its compact size and excellent fuel efficiency. I think it is ideal for short trips. For those who explore more extreme environments, I suggest the TB2S+. This model includes an integrated CO alarm and automatic altitude adjustment, providing you with exceptional safety and intelligence, particularly in mountainous areas. While camping extensively and enduring, the TB MAX is my preferred choice. Its enormous 7.5L fuel tank offers an outstanding runtime, allowing you to stop stressing over constant refueling and simply enjoy the journey.

What Makes These Hcalory Diesel Heaters Stand Out?
Hcalory HBS2 Review: Small Body, Big Power—My “Lightweight” First Choice
As a driver constantly traveling, I dislike it when my vehicle becomes messy with equipment. The HBS2 impressed me with its compact frame and its all-in-one, no-installation design. This small heater is my favorite for traveling light; I can easily pick it up and leave, and it hardly occupies any of my valuable trunk space, due to its compact size of 48x41x21cm.
Don’t be deceived by its size—the claimed 28% boost in fuel efficiency is serious. It uses only 0.12 L/h, and its 3.5L tank can comfortably operate overnight, preventing me from needing to wake up in the cold for refueling. It offers three control methods—Bluetooth, remote, and an LCD panel—with a 1.5-meter extended cable for the panel, which is a game-changer for adjusting the temperature from inside the car. For mountain roads, its manual 2500m and 5000m high-altitude modes ensure efficient combustion, so there’s no risk of it stalling due to lack of oxygen. Coupled with comprehensive safety protections, it’s a convenient and reliable partner for short camping trips and emergency heating.
Hcalory TB2S+ Review: Safety First—A “Golden Shield” for High-Altitude Explorers
As an experienced explorer, my primary concern is safety. The most reassuring aspect of the TB2S+ is its integrated Carbon Monoxide (CO) alarm system. This is more than just a basic warning—when CO hits a hazardous level, it emits a loud “beep-beep” alarm, and at perilous concentrations, it will automatically turn off and show an “E11” error code.
Another important reason I chose the TB2S+ is its intelligent altitude sensor. Previously, I constantly needed to manually change my heater’s settings in high-altitude locations, which was inconvenient. The TB2S+ alters combustion settings automatically according to altitude, guaranteeing consistent and efficient operation whether I’m at a mountain campsite or on even terrain. Featuring a 6L fuel tank and consuming between 0.12 to 0.36 L/h, it is remarkably efficient.
Hcalory TB MAX Review: The Runtime King—Letting Me “Lay Back” in the Cold
Hcalory TB MAX boasts an impressive 7.5L extra-large fuel tank. What is the implication of this? It signifies that you can leave your vehicle in a chilly, isolated spot for several days without concern about the heater depleting its fuel. You can genuinely receive “multiple days of heat from one tank.”
The TB MAX features all the sophisticated functions of the TB2S+, including the remote wireless temperature sensor and automatic altitude adjustment. Its measurements of 52x35x48cm vary slightly from the TB2S+. Featuring a low fuel usage of 0.12 to 0.36 L/h and a substantial 7.5L capacity, it operates for extended periods compared to many diesel heaters. If you’re similar to me—often embarking on extended winter journeys, establishing a basecamp, or residing in an RV—the TB MAX offers unmatched assurance and ease, helping you feel at home even in the wilderness.
Which Hcalory Diesel Heater is Best for You?
- If you’re a “lightweight camper” who values portability and fuel efficiency, the HBS2 is your perfect companion.
- If you’re a “hardcore adventurer” who frequently traverses high altitudes, the TB2S+ is your ultimate safety guarantee.
- If you’re a “comfort-first” traveler who demands long runtime and peak performance, the TB MAX is your best bet.
