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/T air duct splitter 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.
As part of Hcalory's product testing program, I set up the TC2S in my small hunting cabin (about 200 sq ft) in Montana, and also tested it in my garage. September evenings here are already dipping into the 50s, so it was a good time to see what it can do.
The heater surprised me with how quickly it takes the chill out. From a cold start, the cabin warmed up to 75°F in under 15 minutes. For the garage, I run it about 3 hours in the evenings when I'm working on my truck, and it keeps the space comfortable the whole time.
Fuel efficiency is where this unit shines. The 5L tank lasts longer than expected at the lowest setting; it barely sips diesel. Compared to my old 8KW heater, I'd estimate this one uses about a third less fuel, which adds up over a season.
The APP control works, though I mostly use the panel since it's mounted near the door. I like that it has safety protections built in; it shuts down automatically if anything goes wrong, which gives me peace of mind.
The only drawback is that it's not completely silent. There's a noticeable hum, but for a shop or cabin, it's not a big deal. The trade-off for steady heat and better fuel economy is worth it.
All in all, the TC2S feels like a well-built, efficient heater that will be my go-to this fall and winter.
I was looking for something that works both in my RV and at home when the power goes out. The TC2S runs smooth on either setup and I like having the extra safety features built in.
Compact, powerful, and fuel-efficient. I use it in my hunting cabin and it makes the place cozy fast. A little hum while it runs, but nothing that bothers me.
I run this in my garage when I'm working on my truck at night. Keeps the whole space comfortable and doesn't cost me much in fuel. Setup took a little time but worth it once it's running.
