What is a Parking Heater?
3 Answers
Parking heater is an independent vehicle heating device that operates separately from the car engine. Introduction to Parking Heating System: The parking heating system overcomes the limitation of conventional vehicle heating systems that rely on the engine, and can accelerate the vehicle heating process. Certain types of parking heating systems also provide an engine preheating function, significantly improving the cold start performance of the engine, reducing engine wear during cold starts, and enhancing fuel economy. Functions of Parking Heating System: The parking heating system works in coordination with general heating and air conditioning systems to improve vehicle comfort and economy. Early parking heating systems could already utilize the ventilation ducts of the air conditioning system to evenly distribute warm air to all areas inside the vehicle.
The parking heater is a small device installed in vehicles, specifically designed to warm up the engine or cabin while parked, ensuring a cozy start. I remember after installing one in my car, even on winter mornings with temperatures below -10°C, my hands no longer froze. It comes in two types: fuel-based and water-based. The fuel type uses a small amount of diesel for combustion heating, while the water type circulates coolant, also speeding up the heating of the air conditioning. In practical use, it's very convenient—just set the timer, and it works automatically, delivering warm air the moment you get in the car, with fewer instances of frosted windows. It's ideal for drivers in cold regions, like me, who frequently travel to the northeast, making starts much easier while also protecting the engine and reducing wear. Choosing a suitable model costs just a few hundred yuan, and installation is straightforward—just find a shop to do it. The cost-performance ratio is truly high.
From a technical perspective, a parking heater is essentially an independent heating device. Some are mounted directly near the engine, utilizing a small pump or fan to drive the circulation system. Common types include fuel-operated preheaters that burn diesel to warm intake air, or liquid-based systems connected to the coolant circuit for faster heat exchange and temperature rise. Having disassembled and installed one myself, I can attest to its compact design featuring a thermostat, which effectively prevents oil solidification issues during cold starts. Electric heating types consume more energy but are eco-friendly, making them popular in new energy vehicles. Installation should prioritize well-ventilated areas, avoiding exhaust pipe blockages, with thermal efficiency exceeding 80% for notable energy savings. When purchasing, ensure power compatibility—around 200W suits compact cars. Prioritize safety by preventing electrical shorts and regularly maintaining cooling components. This investment significantly extends engine lifespan.
