Upgrade Your Heat: Hcalory TB2 Diesel Heater Review
Intro
Hcalory 's new Toolbox 2 Diesel Heater brings several improvements over the original model, offering better performance, efficiency, and usability for both outdoor and indoor use. Johnny, the automotive parts and accessories influencer provided the breakdown of what you can expect from this upgraded unit.Unboxing and Setup
Right out of the box, the Toolbox 2 Heater comes with everything you need: the diesel heater unit, an AC to DC converter, DC power cord with ring terminals, and a remote control. The unit also includes a blower hose, intake tube with filter, exhaust hose with a muffler, and mounting hardware.One of the key improvements in this model is the larger 1.6-gallon fuel tank, which extends runtime compared to the previous version. The fuel tank features a bottom drain for maximum fuel use and a fuel strainer at the top.
Design and Build Quality
The unit is built well, with insulation around the exhaust pipe and a rubber isolator on the fuel pump to reduce the ticking noise. While this model still has some noise, it’s significantly quieter than the older versions. The app functionality has also been improved, offering better control over settings like altitude adjustment, with the ability to work at altitudes up to 10,000 feet.Power and Efficiency
This diesel heater can run off a smaller 12V power station without tripping the socket, making it ideal for off-grid setups. During testing, the unit drew a consistent 123W, with brief spikes that didn’t cause issues. Unlike cheaper models that often struggle to start, this heater fired up easily without smoke, providing a steady stream of hot air.Once running, the unit’s power draw remained low—around 12 to 15 watts, with peaks up to 35W at full speed. This efficient power usage makes it perfect for long runs, and it worked well with Johnny RV setup. After 4 hours of use, the fuel tank showed only a slight drop, proving its efficiency.
Sound and Performance
The unit's operation is notably quieter than older models. While the fan noise is more pronounced, it’s much less intrusive than the ticking of the fuel pump on previous versions. Adding a muffler further reduced noise, making the heater even more suitable for indoor use, such as in a tent, RV, or cabin.A sound check at 7 feet away confirmed that, at lower power settings, the noise is minimal. At 50% power, the fuel pump tick was barely audible. The unit provides both efficient heat and low noise, making it a great option for small spaces.
Safety and Monitoring
Carbon monoxide is a concern with any combustion heater, so monitoring any leaks is essential. Johnny used a simple gas detector to ensure no harmful fumes were escaping, and it provided peace of mind. It’s always good practice to check for leaks periodically, especially after extended use.Heating Efficiency in My RV
Johnny tested the heater in his RV to see how well it performs in a confined space. The exhaust pipe reached temperatures of 236°F, but the outer casing remained cool enough to touch. The heater quickly warmed up the interior of Johnny RV, raising the temperature from 58°F to 70°F over several hours, even in the cold weather.
To prevent heat buildup under the RV, Johnny added an exhaust extension that safely directs fumes away. The unit worked flawlessly, providing consistent heat while maintaining safe temperatures around the exhaust area. He also placed a welding mat underneath to protect the RV’s plastic port from excessive heat.
Conclusion
The Hcalory Toolbox 2 Diesel Heater is a major upgrade over its predecessor. It’s quieter, more efficient, and offers better control with improved app functionality. The larger fuel tank and reduced power draw make it ideal for long-term use in off-grid environments, whether in an RV, cabin, or tent. If you’re looking for a reliable and efficient diesel heater, this model is a great choice for staying warm and safe without the noise and hassle of cheaper alternatives.
