I have a melanine rack planned out and I was planning on using a single strip of 11" flexwatt heat tape right down the back of the rack to heat it. But when I went to boamaster.com I saw these things called heat panels??? Im just curious if theyre the same thing as heat tape or like what they are I guess? Im still 99% sure Im going to buy heat tape because its much cheaper but was just wondering what heat panels were...
