A parking heater is a device that provides heat when a vehicle is parked. There are two main working principles: liquid cooling circulation system and air heating system.
Liquid cooling circulation system
This type of parking heater is connected to the vehicle's cooling system and utilizes the vehicle's hot coolant to generate heat. When you activate the parking heater, it will guide the coolant to a heat exchanger through an independent pump, and then transmit warm air to the interior of the vehicle through a fan. This system has a clear advantage, which is that it not only heats up the air inside the car, but also preheats the engine, helping to improve combustion efficiency during start-up.
Air heating system
Unlike liquid cooling circulation systems, air heating systems do not need to be connected to the vehicle's cooling system. They use independent heat sources, usually fuel or diesel, to generate heat through combustion. These systems send hot air into the car through fans, providing warmth. The air heating system is suitable for car owners who do not want to be connected to the vehicle's cooling system, or it is easier to start in extremely cold areas.
