V vs. 120V – Are 120 volt SunTouch mats more efficient than 240 volt?
No. Both have the same efficiency and both mats use 12 watts per square foot. 240 volt mats operate with half the amperage (current) of 120 volt models. The 240 volt models are more popular for larger installations of over 150 Sq Ft, for rooms where you want a lower amperage service, or for rooms where 240V is already in place. Once again, SunTouch has thought of all the options!
