Many people are looking for the most inexpensive and easiest to install heating cable for their pipes which is what is called constant wattage pipe heat trace cable. It is a smaller cable as opposed to self-regulating cable. There are five manufacturers of constant wattage cable and we sell three of them. EasyHeat makes AHB, Wrap-on and King Electric makes their CWP. There are also a couple of other brands we do not sell called Frost King and M-D Building Products which are similar.
