Why preheating matters.
Every pilot knows this situation. You arrive at the airport on a cold winter day.
The engine is cold-soaked. You still try to start — because you want to fly.
Fuel condenses in the intake runners, oil is thick, clearances are large, and the
starter works against maximum resistance. If the engine doesn't start immediately,
you keep cranking: battery voltage drops, wear accumulates.
Experienced engine builders estimate that a very cold start contributes to wear
comparable to dozens of hours of normal operation — or consider the
cost of an earlier starter rebuild.
The PAEH-5kW changes this situation by preheating the entire engine compartment
before the first turn of the propeller, bringing the engine closer to its normal
operating condition.
- Oil flows instead of resisting
- Fuel vaporizes instead of condensing
- Starter and battery are less stressed
- The first start is no longer a harmful cold start
