Beschreibung
Zusammenfassung:	A main-frequency electrically powered fluid heater which includes a coreless transformer and an electrically conductive jacket through which flows the fluid to be heated; the coreless transformer comprises a primary winding electrically insulated from the jacket but at least partially surrounding it, and a secondary winding arranged so as to be linked by magnetic flux from the primary winding; secondary winding being electrically insulated from the primary winding, but electrically connected to the jacket, so that the jacket is heated both by resistance heating and by eddy current heating.
