10 kW diesel parking heater for engine coolant, Vantaa

Operating principle:

The heater's main engine drives the fuel pump, combustion-supporting blower and the atomiser. The fuel pump delivers suctioned fuel through a fuel line to the atomiser. The atomiser mixes the fuel with air drawn in by the blower and sprays it into the main combustion chamber by centrifugal force. A hot glow plug ignites the air-fuel mix, it burns completely and then passes into the rear combustion chamber. Heat transfers through the inner wall of the water jacket and the upper cooling fins to the medium in the water-jacket cavity – the coolant. After heating, the medium circulates through the whole circuit by a circulation pump (or by thermal convection) to provide heating. The combustion exhaust gases exit via the exhaust pipe.

⚠️ Diesel-heater Safety instructions

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

1. Exhaust routing (Main rule)

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

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

• CO alarm: Always install a quality carbon monoxide (CO) detector in the space. It's a cheap life insurance.

  
  

2. Exhaust temperature and insulation

The exhaust pipe reaches very high temperatures during operation.

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

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

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

  
  

3. Combustion air and heated air

• Separate air intakes: Ensure the heater exhaust is not near the unit's combustion air intake or the heated-air intake. 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 run onto the hot exhaust pipe.
