The He 114 was never a great success, was not built in large numbers, and served with the Luftwaffe for only a short time.

The airplanes were assembled and given a complete overhaul before entering service at Roslagens flygflottilj (F2) in Hägernäs under the designation S 12 (S being an abbreviation for 'reconnaissance aircraft' in Sweden).

[1] In 2012, two divers discovered the wreckage of a Heinkel 114 at the bottom of Lake Siutghiol, in Romania.

Near the Heinkel were also sections of two other seaplanes: a Blohm & Voss BV 138 (initially thought to be a Savoia-Marchetti S.55) and a Junkers W 34 (discovered in 2013).
