Introducing the 12V 8KW Hydronic Diesel Heater, a revolutionary dual-function heating system designed for RV living, marine applications, and commercial vehicles. This powerhouse combines air heating and water heating capabilities in one compact unit, delivering unmatched efficiency and versatility.

1. Dual Heating System with 7 Adjustable Outputs
Experience precise temperature control with 7 adjustable heat levels, ensuring stable thermal output for both cab warmth and hot water supply. The integrated hydronic system allows simultaneous air heating via ducted vents and water heating for showers, sinks, or engine preheating.

2. RV & Marine Hot Water Solution w/ Diversion Valve
Equipped with a 3-way diversion valve, this heater intelligently switches between cabin heating and domestic hot water modes. In summer, close the valve to dedicate 100% output to water heating—perfect for RV showers or boat galley use.

3. Multi-Application Heating: Engines & Cabins
Beyond RV and boat comfort, it preheats diesel engines for smooth cold starts and supports battery warming in electric cargo vans. Note: Not recommended for passenger EVs due to installation constraints.

4. Smart LCD Display & Real-Time Remote Sync
The ST32-chip controller drives a cryogenic-resistant LCD screen that monitors runtime data, including motor RPM and temperature. It diagnoses faults instantly and suggests fixes—no manuals needed! The rechargeable remote syncs data within 500 meters, displaying live stats like aluminum block temp and system status.

5. Aviation Connectors & Aluminum Alloy Housing
Built for harsh environments, it features corrosion-resistant aluminum casing, oversized heat sinks, and aviation-grade connectors for vibration-proof wiring. The self-priming pump uses Japanese bearings for silent, reliable operation.

6. Auto Mode & 43% Fuel-Saving Eco Mode
Activate Auto Mode for -40°F extreme cold or engage Eco Mode to slash fuel use by 43%. Eco Mode’s auto-carbon-clean function clears 70% soot buildup in 30 minutes—no disassembly required!

7. High-Temp Alerts & 4 Precision Thermostat Modes
The 265°F overheat protection triggers audible alerts and on-screen solutions. Choose from 4 modes:

• Time-Based Heating (ignores water sensors)
• Dual-Temp Range (maintains between min/max settings)
• Max-Temp Shutdown (stops at target temp)
• Smart Cycling (restarts at min temp)

8. Commercial EV Battery Preheating
Solve winter range anxiety! This unit preheats electric cargo van batteries, countering "range cliff" drops while eliminating parasitic drain from cab heaters.
