Abstract The air heat pump (HP) driven from GTP, created on the basis of aircraft GTE removed from service, is considered. The heat pump uses ambient air from negative (−40 °C) to positive (+15 °C) temperature values as a low-grade heat source and provides heating temperature in a range from 100 to 250 °C with the performance factor 2.5–3.2. The high technological burning of gas decreases its consumption for heating on the average by a factor of 1.5 in comparison with an ordinary boiler-house. Cold HP exhaust within the range of − 50 … − 80 °C is fed both to a drive GTP and an integrated electric energy generating GTP, this increasing their specific power by a factor of 1.2–1.4 and efficiency up to a factor of 1.05–1.1. In standard HPs designed for operation with low-grade heat sources from +5 to +10°C, the heating temperature does not exceed +60 … +65 °C for the performance factors indicated.
