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.

Quiet and warm

Easy setup and works perfectly. Bluetooth connected without a problem. You'll need to buy ducting separately. Super quiet once it's up and running.

To me is just perfect reed the review

Ok, I am a mechanic and I like things a little bit different than others, so I did a few changes to make it more efficient and durable in some ways. Keep in mind, I used this heater for camping and sometimes to warm up the garage when it's too cold outside, and so I can work comfortably. So i added a fuel filter and i don’t used the power source they provide because this unit is a 12/24 volt so i added a Milwaukee battery adapter and currently used a 12ah Milwaukee battery to run the unit and so far i have run the unit for 3.5 hrs and still have some battery energy left and is really efficient on the diesel consumption is really economical on that part. And the best part is that I went camping, temperatures dropped to 30 degrees, and I was able to turn on the unit from the app on my phone, which is a perfect way to control the heater, and there is no need to go out in the cold to turn the unit on. The hose that comes with the unit is not the best retractable hose that won’t last long, so I added to that hose a long boat heater flexible hose. It's better this way. Good luck, and I hope this is helpful. This unit is perfect for me

Far better than others

I got this to replace a cheaper one I had that seemed to fail at the worst times. I will update after this weekend's trip to the higher altitude (around 7500ft) on whether it had failures with the altitude adjustment or not. So far, it looks and seems to work great out of the box. Adding onto my original review. Used this at 7400ft. The alt correction worked awesome. Ran it for probably 24-26 hours straight most of the time on full power as it was 26-30°F. Used 26% of my 100Ah battery. Used a full tank of fuel. Great heater, will recommend.

The app for this works great

This is a great buy. I am building a little studio apartment, and I think this is going to be a great addition. First off, I have no power, so this is an off-grid heater. It runs great on a small power bank. Flawless setup and super easy to navigate with the app.
