Le Hcalory TB2S+ diesel heater is the newest upgrade from Hcalory, improving on the earlier model Toolbox 2 with smarter controls, better safety, and higher efficiency. As a portable heating solution, it’s designed for use in RVs, trucks, boats, garages, and camping tents—basically anywhere you need reliable warmth in cold weather. If you’re considering an Hcalory 8kW diesel heater, the TB2S+ is one of the best choices.
Let’s see what it has upgraded and how the performance is.
Hcalory TB2S+ vs TB2: What’s Upgraded?

- 1.5m Switch Extension Cable – Makes it easier to operate from inside a tent or cabin.
- Improved Fuel Cap – Reduces leakage risks during travel.
- Latest P2.2 Control Panel – Smarter interface with features like timers and altitude mode.
- Wireless Remote with CO Alarm – Adds temperature sensing and carbon monoxide safety warning.
How is the Hcalory TB2S+?
Hcalory TB2S+ Dimensions & Design
Anyone who has camped in winter or worked in a cold garage knows the struggle: bulky heaters are hard to install, while smaller ones often don’t provide enough heat. The Hcalory TB2S+ dimensions (54 × 53 × 27 cm) strike the perfect balance—compact enough for portability, yet large enough to house a Réservoir de carburant de 6 L for extended runtime. It’s all-in-one structure means no complicated setup: just place it in your RV, truck, or tent, and it’s ready to go. The redesigned combustion system doesn’t just save space, it also boosts heating efficiency so you stay warm faster.
Heating Performance
Waking up shivering in a frozen RV is the worst start to a day. The Hcalory 8kW diesel heater ensures that doesn’t happen. With powerful heat output, it comfortably warms truck cabins, RVs, boats, and tents. Thanks to an optimized combustion chamber and smarter fuel algorithm, it delivers up to 38% better efficiency. That means more hours of steady warmth on the same amount of diesel—no more worrying about your fuel running out in the middle of the night.
Hcalory TB2S+ Hose Size & Airflow
Small heaters often create uneven heating—hot air near the outlet, but cold corners elsewhere. The Hcalory TB2S+ hose size has been upgraded to 90mm, which significantly improves airflow. With reduced resistance, the heater pushes warm air more evenly across your space, so you don’t end up with hot and cold zones. It warms the entire interior quicker, giving you comfort from head to toe.
Power & Fuel Efficiency
Many diesel heaters are either too power-hungry or limited to vehicle-only setups. The Hcalory TB2S+ power consumption is 0.12–0.36 L/h; lower consumption means lower costs while extending runtime. Even better, it’s compatible with 12V and 24V DC systems as well as 100–240V AC with the included adapter. That flexibility means you can use it in your van on the road, in your garage at home, or even as an emergency heater during a power outage. Whether you need an Hcalory 12V 8kW diesel heater for camping or a reliable backup for your house, the TB2S+ adapts to your lifestyle.
Control & Convenience
Traditional diesel heaters always with limited controls. Hcalory TB2S+ features 3 types of control:
- Smartphone App (Bluetooth-enabled) to adjust heat from anywhere.
- Wireless Remote with built-in temperature sensor and CO alarm for added safety.
- LCD Control Panel with programmable timers and auto start/stop.
With such control types, the Hcalory TB2S+ heater makes you no longer step outside in the cold to fiddle with buttons, as the control is literally in your hands.
Built for Safety & Durability
The TB2S+ doesn’t just focus on performance—it’s also built with safety in mind. It features a CO alarm sensor that sounds a loud “beep-beep” alert when levels reach 70% of the danger threshold, giving you time to ventilate. At critical levels, the heater automatically shuts down, flashes the “E11” code, and triggers a continuous alarm for maximum protection. On top of that, the unit is CE certified, meeting strict EU safety standards for reliability and peace of mind.
