A truck/bus water-heated parking heater is a heating device independent of the vehicle’s engine. It heats the coolant to provide interior heating and engine preheating. The following is a description:
Operating Principle
After starting, a metering pump delivers fuel from the fuel tank to the preheating system. The glow plugs ignite and draw in ambient air. The fuel is atomized by the glow plugs, and the fuel-air mixture ignites. The heat generated by the combustion heats the coolant in the heat exchanger. Driven by a circulating water pump, the coolant circulates throughout the piping system, transferring heat to the radiator, defroster, and other components within the vehicle, providing interior heating and also preheating the engine.
Main Functions
Interior Heating: Heats the engine’s circulating medium—the antifreeze—and dissipates the heat through the radiator to the interior, providing a warm environment for the driver and passengers and also defrosting the windshield.
Engine Preheat: Preheats the engine while the vehicle is parked, ensuring a more comfortable temperature upon starting. This reduces cold start wear, battery load, and fuel consumption. Some vehicles also offer the convenience of frost-free windows. Product Advantages
Engine Protection: Prevents wear and tear caused by cold starts, extending engine life by approximately 30%.
Easy to Use: Preheats the engine via remote control and a timer system without starting the engine, effectively providing a car heater.
Energy Saving and Environmental Protection: Low emissions and fuel consumption make it more energy-efficient than traditional electric heaters, and some models can even reduce emissions.

Product Features:
Constant temperature control, low power consumption, safety, fast heating, fuel efficiency, low noise, easy installation, and simple operation.

Using a car in cold winter weather often causes significant impacts due to fluctuating temperatures. Cold starts can be difficult in temperatures between -10°C and -15°C, which increases engine wear and reduces engine life. In temperatures between -30°C and -40°C, a car may experience misfires.

Simply flip the water-heated parking heater switch briefly and wait 10-15 minutes for the water temperature to reach 80°C. The car starts, and the cab becomes heated. It heats quickly and maintains a constant temperature.

It is suitable for cold-starting water-cooled engines such as heavy-duty trucks, special-purpose vehicles, engineering vehicles, and generator sets. When combined with a radiator and defroster, it can independently heat the cab and defrost the windshield of mid-sized trucks and engineering vehicles.
