Powerful 12V 8KW Dual-Function Diesel Heater
Experience unmatched versatility with our 8000W diesel heater, engineered for RV heating, marine use, and commercial EV battery preheating. This air/water combo unit features a 3-way valve to toggle between warm air delivery and hot water supply—perfect for summer water heating or winter cabin warmth. With 7 adjustable power levels, it maintains consistent heat output while preventing dry burns.

Intelligent Control & Monitoring
The industrial-grade circuit board with ST32 chip powers a low-temperature LCD screen that displays real-time motor RPM, water temperature, and fault diagnostics. Paired with a rechargeable bidirectional remote, it syncs data across 500+ meters and offers auto-sleep functionality. The 4 working modes adapt to any scenario:

• Mode 1 (Time Setting): Hourly adjustments, with or without water sensors.
• Mode 2 (Auto-Thermostat): Maintains temperatures between user-set highs/lows.
• Mode 3 (Max Temp): Single-run operation until target temperature is reached.
• Mode 4 (Max/Min Temp): Shuts down upon hitting max temp; reactivates at min temp.

Advanced Engineering for Harsh Conditions
Built with an aluminum housing, oversized heat sink, and 8-slot magnetic motor (6,200 RPM max), this unit ensures durability. The self-priming water pump uses Japanese bearings, while aviation plugs secure all connections. It automatically adjusts for high-altitude operation (0–5,800m) and includes fuel-saving technology that reduces consumption by 43% and self-cleaning carbon deposits.

Critical Applications
Beyond RV living and boat heating, this heater preheats diesel engines for smooth cold starts and supports commercial electric vehicles by extending battery range in freezing temperatures. Note: Not compatible with sedans due to space constraints.

Safety & Efficiency
The auto-thermostat prevents overheating (265°C+ alarm), while thermal expansion protection engages at 120°C. Choose Auto Mode for subzero conditions or Fuel-Saving Mode for eco-friendly operation. Elevate your heating solution with this industry-leading diesel air/water heater—where innovation meets reliability.
