The operation of the parking heater water pump

The heat exchange process occurs when the engine heats up. As a result, antifreeze passes through the power unit, cools it and takes heat away. Then the coolant under pressure, which is created by the pump, enters the stove radiator. The latter heats up like a radiator battery. The stove fan blows cold air through the radiator.

Heat exchange takes place again when heat from the radiator passes into the air and the latter cools the radiator. Then the air, warming up, enters the interior. After cooling, it enters the engine and cools the power unit again. But sometimes one water pump is not enough to fully heat the entire volume of air directly in the cabin. Then an additional device is installed. We are talking about the interior PIERBURG brand Water Pump, parking heater. It ensures stable circulation of antifreeze.
