I was getting a little nervous flying behind a 40 year old fuel-air bomb in continuous ignition.

Also, it was getting harder and harder to find someone who could do the pressure decay test.

Put in a separate heater hourmeter, to extend the inspection intervals and usable life.
Otherwise they assume 1/2 your flight time is with heater.

Years back I switched to the C&D heater. Lower maintenance, etc.
The install proved to be a bit tricky, and the heater output seems a bit less.

But no more pressure decay tests.
