HCALORY 8KW Diesel Heater, HBH-3 Diesel Air Heater with App Control 10-Temperature Settings, 18% Boost in Burning Efficiency, Auto Start-Stop, and 240V AC 12V 24V DC, for Car, Campers, Van, RV

• 【Rapid Heating & Reliable Cold Start】 The Hcalory diesel heater utilizes an improved aluminum heat exchanger with 18% higher combustion efficiency. The optimized glow plug preheats for one minute before ignition and continues running for another 30 seconds afterward to ensure stable ignition—even in temperatures as low as -20°C. You will feel warmth after just 3 minutes, and the outlet temperature reaches 100°C within 5 minutes. With an adjustable 8 kW output, fuel consumption ranges from only 0.11 to 0.35 L/h. The 5-liter fuel tank allows for extended heating periods, making it suitable for spaces of 20–25 m².
• 【Auto Start-Stop & Precise Temperature Control】 Equipped with a sensitive temperature sensor, the unit continuously monitors the ambient temperature. The fuel pump remains in standby mode and activates only when needed. The system automatically switches on and off to maintain the room temperature within the set range. This reduces fuel consumption, prevents drastic temperature fluctuations, and ensures a comfortable, uninterrupted sleep throughout cold nights. The control unit can be conveniently mounted inside the vehicle or room using the included 1.5-meter extension cable.
• 【5-Level Altitude Mode (1,000–5,000 m)】 Unlike conventional heaters, this model features five selectable altitude settings (1,000 m / 2,000 m / 3,000 m / 4,000 m / 5,000 m). The intelligent control system automatically adjusts the air-fuel mixture to compensate for thin air at high altitudes. This ensures full heating performance is maintained during mountain trips or high-altitude camping, while preventing incomplete combustion and smoke generation.
• 【Three Flexible Control Options】 Control the diesel heater exactly how you prefer using one of three methods: a Bluetooth smartphone app, an LCD control panel, or a wireless remote control. The app allows for convenient configuration of timer functions, the 10 heat settings, and the intelligent auto-start/stop function. The remote control operates with a range of up to 30 m, while app control works up to 10 m away—offering maximum flexibility for camping, RVs, and trucks.
• 【AC/DC Dual Power + Safety Protection】 Supports both 220–240 V AC power adapters for stationary use at home or campsites and 12 V / 24 V DC vehicle power systems. An integrated multi-layer safety system protects against overheating, short circuits, reverse polarity, and overvoltage.
• Warning: Exhaust gases must be vented outdoors to prevent the risk of carbon monoxide poisoning.
