FIELD: electricity.
SUBSTANCE: electrical conductor is placed between at least a first electrical contact and a second electrical contact. A ferromagnetic conductor at least partially surrounds the electrical conductor and is at least partially placed along its length. Upon feeding alternating electrical current, the electrical conductor induces an electrical current in the ferromagnetic conductor which is sufficient to heat the ferromagnetic conductor owing to resistance to temperature of at least about 300°C.
EFFECT: heating system according to the invention provides an improved heating method, which enables to extract hydrocarbons, hydrogen and/or other products from different formations containing hydrocarbons.
