Heat cables manufactured by Easy Heat, Frost King and Wrap On are not worth buying. I can’t say it more plainly than that. These cables are typically sold at box stores like Home Depot and Lowes and they should be ashamed to sell them. Why? For starters, they are only warrantied for 1 or 2 years for a very good reason. That is as long as they last (I’ve attached warranties from Wrap On and Frost King below). Homeowners buy bad cables because they are cheap and because they believe what the packaging says. Sadly, we replace thousands of feet of this junk every year. We install more heat cables that any firm in the country and fully 20% of the work we do is the replacement failed ice dam heat cable systems manufactured by Easy Heat, Frost King and Wrap On.
Beyond the short lifespan, heat cables by Easy Heat, Frost King and Wrap On are energy hogs. While they only typically draw 5 watts a foot, they run at 100% while they are plugged in, regardless of the surrounding temperatures. They are what’s called ‘constant wattage’ cable. Our ice dam heat cables are self-regulating. They sense the outdoor temperatures and draw only the electricity they need to do the job. The net result is that cheap cables made by Easy Heat, Frost King and Wrap On chew through electricity. So, somewhat paradoxically, our heavy duty ice dam heat tape runs at over twice the peak wattage of the cheap stuff, it uses far less electricity over a season.
Don’t buy Big Box heat cable.
