A dual-person electric heating blanket having a receiving bag and a remote controller, the receiving bag has therein a first and a juxtaposed second heating wire which are connected with a controller box; the remote controller includes a circuit board being electrically connected, a pattern interface, a switchable switch and a signal emitting end; the pattern interface has thereat a first and a second position juxtaposed with each other, the first position has thereat a first pattern, and the second position has thereat a second pattern, the first and second patterns are respectively connected with a first and a second circuit on the circuit board; thereby, when a user faces to a front or a rear end of the receiving bag, by switching between the first and second circuits with the switchable switch, the first pattern corresponds to the first heating wire and the second pattern corresponds to the second heating wire, and by emitting control signal from the signal emitting end, heating temperatures of the two sets of heating wires are controlled respectively.
