10 kW diesel parking heater for engine coolant, Vantaa

Principle of operation:

The main engine of the heater drives the fuel pump, the combustion-supporting air blower and the atomiser. The oil pump sends suctioned fuel to the atomiser via the fuel line. The atomiser mixes the combustion air drawn by the blower with the diesel, spraying it into the main chamber by centrifugal force. The hot glow plug ignites the air, it burns out completely and then returns to the rear combustion chamber. Heat is transferred through the inner wall of the water jacket and the cooling fin above into the medium in the water-jacket space – the coolant. After heating, the medium circulates through the entire piping by the circulation pump (or by thermal convection) to provide heat. Combustion exhaust gases leave via the exhaust pipe.

⚠️ Diesel heater Safety instructions

The diesel heater combustion process consumes oxygen and produces dangerous exhaust gases. Incorrect installation can lead to carbon monoxide poisoning or fire.

1. Exhaust routing (Most important rule)

• Exhaust to outside only: Exhaust gases must be routed entirely outside the building, tent or vehicle using a metal exhaust pipe.

• Sealing: Ensure the exhaust connection to the heater body is sealed with the supplied clamp. Even a small leak into the interior can be fatal.

• CO alarm: Always install a good-quality carbon monoxide (CO) alarm in the space. It is inexpensive life insurance.

  
  

2. Exhaust temperature and insulation

The exhaust pipe reaches very high temperatures in use.

• Max temperature: Diesel-heater exhaust temperature at the outlet can reach up to 250–450 °C depending on power. The metal pipe itself can glow hot.

• Penetration: If the exhaust passes through a wall or floor, use a non-combustible insulating sleeve (e.g. fire wool or a separate metal penetration sleeve). The pipe must not touch wood, plastic or other combustible materials directly.

• Clearance: Keep the exhaust pipe at least 10 cm away from any melting or combustible materials along its entire length.

  
  

3. Combustion air and heated air

• Separate air intakes: Ensure the heater exhaust is not near the device's own combustion air intake or the inlet for the heated interior air. Otherwise the unit may draw its own exhaust back in.

  
  

4. Fuel handling

• Position the fuel tank so that, in the event of a leak, diesel cannot flow onto the hot exhaust pipe.
