The real culprit? The lead-in wires. These heaters get incredibly hot. If those wires aren&rsquo;t sealed perfectly, the insulation just&hellip; gives up. It burns out, the wires short, and suddenly you&rsquo;ve got a dead unit on your hands.</p> <h2 id="the-problem-with-heat-creep">The problem with &ldquo;heat creep&rdquo;</h2> <p>Heat doesn&rsquo;t just move in one direction. In a ceiling installation, it actually migrates backward, crawling right toward the electrical connections. Most standard heaters use basic heat-shrink or some cheap silicone. It looks fine at first. But over time, that stuff gets brittle. It cracks. Then the bare wires touch the chassis or each other, and that&rsquo;s when things go wrong. We handle this by potting the leads. Basically, we encase the wire in a high-temp ceramic or a specialized silicone compound. It creates a physical wall that tells the heat, &ldquo;You stop here.&rdquo;</p>
