Solid upgrade from the TB2, way quieter too

I was invited by Hcalory to try out the new TB2S Diesel Heater this September, right before our fall camping season. I installed it in my 24ft Winnebago RV and gave it a proper test on a three-night trip to Colorado.

Setup took me a little while since the directions aren't the clearest, but once you figure it out, it's pretty straightforward. I liked that they included the 1.5m extension cable so I could mount the control panel inside, no need to go out in the cold just to adjust.

Performance-wise, this thing is a serious upgrade from the TB2. It fired up quickly, and within 5-7 minutes, the RV felt toasty. It stayed steady at 72-75°F on level 2. The 6L tank lasted me the entire trip with some fuel left over, which is impressive.

The APP control is handy when I'm already in bed and don't want to move. Noise level is just a soft hum, much quieter than the last diesel heater I had. My only minor complaint is that the app menus could be a bit more intuitive, but once you get used to it, it works fine.

Overall, the TB2S feels solid, burns less diesel, and gives consistent heat. Definitely something I'll keep in my RV for the whole winter.

Runs quiet and keeps my RV warm

Hcalory invited me to test their TB2S this September, just as the evenings started to cool down. I noticed right away how quiet it runs compared to my old heater. The automatic Start-Stop is convenient, and fuel consumption seems really low. So far, it's kept my RV warm on two overnight trips.

Low Fuel Use

I was invited by Hcalory as a product tester for the new TB2S. Nights are already getting chilly where I live, so I tried it during a weekend campout. The heater fired up quickly and kept the tent cozy without burning through much diesel. Really impressed with how efficient it is definitely feels like a solid upgrade from the older model.

fuel efficient and quiet upgrade

What I noticed right away was how fuel-efficient this thing is. Heat output is strong but steady, and the noise level is low, just a soft hum. I'd call this a solid upgrade if you've ever owned the TB2.

Great RV Heater With Peace of Mind

Used it in my RV for the past few nights. The Start-Stop function makes it super convenient. I don't have to babysit it at all. Love the safety features too, gives me peace of mind with my kids sleeping inside. Honestly feels like a heater designed for people who travel a lot.
