Warm air production and safety by demisting the panes

The heater is an integral part of the engine cooling system. However, it contributes significantly to the climate system ensuring the production of warm air.  The heater is often located behind the dashboard or in the HVAC module.  

Hot coolant from the engine block passes through the heater, warming up the intake air blown on its surface by the interior blower. The air gets warmer and can be forwarded into the car cabin. 

As heater produces warm air during cold days in autumn and winter, it significantly improves safety by shortening the demisting of the vehicle’s panes.

Nissens' Solution

  • OE Matching Quality

    All Nissens’ heaters are designed, manufactured and tested to match OE product quality. 

    The heater development process includes a number of life tests, examined and tested by means of vibration, pressure impulse, thermal expansion, corrosion and bursting eliminating the risk of leakage, insufficient heating performance or quality problems such as odours or oil residues etc.

  • Competitive Range

    Product range with +350 items covering more than 1050 OE numbers of cars, vans and trucks.

  • Easy Installation

    Nissens’ heaters are thoroughly finished in every detail.

    They fit smoothly into the mounting cassette in the dashboard/HVAC module, thus ensuring a smooth and quick installation.

    If required, selected heater models are equipped with additional connections and extra foam rubber.

Nissens' Product Benefits

  • Optimized Airflow

    Extra foam added on selected heater models to ensure an optimized airflow.

  • Better Mechanical and Thermal Stress Resistance

    Tanks made of high-quality plastics, no recycled plastic mixtures applied, to ensure strong mechanical and thermal stress resistance.

  • High Heating Performance

    Specially designed turbulators inside the heater core tubes ensure up to 15% higher heating performance.

  • High Thermal Stress Resistance

    Tank gaskets made from EPDM material preventing bursts and shrinkage when the unit is aged and exposed to extreme temperatures during normal operational conditions.

  • Efficient Heat Exchange

    Nissens’ special designed fins with louvres inside the core tubes ensure a highly efficient heat distribution.

Technical Details

Scale that precipitates from water applied instead of a proper coolant may block the heater core limiting the coolant flow. Sediment and grime from poor quality coolants, wrong coolant mixtures or residues of cooling system leak stops will also accumulate in the heater tubes limiting flow thus operation. 

Worn-out or broken thermostat valve may cause a restricted coolant flow thus preventing the heater to operate properly.

Due to its position in a damp environment, the heater is often exposed to corrosion which may cause leakages.

Lack of coolant caused by leakages (in other components as well) will result in improper heater operation.
