10 kW diesel parking heater for engine coolant, Vantaa

Machine principle:

The heater's main engine drives the fuel pump, the combustion air fan and the atomiser. The oil pump sends the drawn fuel to the atomiser through the fuel line. The atomiser mixes the fuel with the air drawn in by the combustion fan and sprays it into the main chamber by centrifugal force. A hot glow plug ignites the mixture; it burns fully and then returns to the rear combustion chamber. Heat is transferred through the inner wall of the water jacket and the upper cooling fin to the medium in the water jacket — the coolant. After heating, the medium circulates around the whole piping by the circulation pump (or by convection) to provide heating. The heater's combustion exhaust is expelled through the exhaust pipe.

⚠️ Diesel heater safety instructions

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

1. Exhaust routing (Main rule)

• Exhaust outside only: Exhaust gases must be routed completely 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 quality carbon monoxide alarm in the space. It is cheap 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 rise up to 250–450 °C depending on power. The metal pipe itself can glow hot.

• Penetrations: If the exhaust pipe passes through a wall or floor, use a non-combustible insulation (e.g. mineral wool or a separate metal penetration sleeve). The pipe must not contact wood, plastic or other flammable materials directly.

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

  
  

3. Combustion air and heated air

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

  
  

4. Fuel handling

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