At what rate does the Piper Seminole heater burn fuel?

Fuel burn for the normally-aspirated model will be about 22.4 GPH at 7000 feet and 75 percent. For the Turbo, it will be 24 GPH at 20,000 feet. At lower altitudes, the speeds between the two are five to 10 knots apart. Seminoles shine in short-field work.
