What is a parking heater system?

The parking heating system is an independent auxiliary heating system on the vehicle, It has no direct connection with the engine. It can be used after the engine is turned off, or it can provide auxiliary heating during driving. It heats the coolant in the water tank by burning the fuel in the car to heat the cabin and the engine without starting the car. The parking heating system overcomes the limitation of ordinary vehicle heating systems relying on the engine, and can increase the speed of vehicle heating. Some types of parking heating systems also provide an engine warm-up function, which greatly improves the cold start performance of the engine and reduces engine wear during cold starts. This system is widely used in passenger cars, passenger buses, engineering vehicles, yachts and other fields.

How the parking heating system works

A small amount of fuel is extracted from the fuel tank to the parking heater combustion chamber, and then ignited by the igniter to obtain an open flame, the combustion chamber is connected to the coolant pipeline of the water tank. The heated coolant circulates in the car and flows through the warm air radiator to heat the cabin. At the same time, the engine is also preheated. There is no need to start the vehicle or the engine to participate in the whole process. Generally speaking, 20 minutes of heating can make the car warm, the engine is fully warmed up, and the ice and snow on the windows will be melted. Depending on the size of the heater, the amount of fuel required for one heating session varies from 0.2 liters to 0.3 liters.

The parking heating system is divided into two types: water heating system and air heating system according to the medium. According to the type of fuel, it is divided into gasoline heating system and diesel heating system. Large trucks, construction machinery, etc. mostly use diesel gas heating systems, and family cars mostly use gasoline water heating systems.
