-Compared to an EV without a heat source that is heated only by air conditioning, the combined use of a radiant heater and air conditioning can provide the same warmth while using about 14% less energy. -The heater also features a safety design that lowers the temperature of the contact area the moment it is touched, and also lowers the heater temperature while contact is detected. -Installed in Toyota's bZ4X, RZ, and RX models.
