An electronic cigarette vaporizer that includes a heating element and further includes or co-operates with an electronics module that (i) detects characteristics of the resistance of the heating element and (ii) uses an inference of temperature derived from that resistance as a control input. The temperature of the heating element may be inferred from data stored in the electronics module that has been empirically obtained for a specific heating element design. The electronics module controls the power delivered to the heating element to ensure that it is no higher than approximately 130° C., plus an error tolerance.
