Procedure for releasing heat by weak current, created in the secondary of a transformer, applicable especially to the heating of beds, which consists of making use of the weak current originating in the secondary of a transformer, by calculating the coils of the primary, the secondary coils being connected to an unconventional resistor, the purpose of the primary coils being the control of the consumption of the said resistor, since the voltage is different in the secondary depending on the position of the switch in the primary coils, the aforementioned resistor being made of flexible copper wire with a coating of silicon. <IMAGE>
