You&rsquo;ve got thick steam everywhere and intense, localized heat coming off the heater. If the seal on the lead-wires isn&rsquo;t perfect, the insulation just burns out. Once that happens, you get carbonization, a short circuit, and a dead heater. Fast.</p> <h2 id="the-thermal-aging-headache">The &ldquo;Thermal Aging&rdquo; Headache</h2> <p>Here is the problem: most cheap heaters just use a bit of glue or some low-grade silicone to seal the spot where the heating element meets the power wire. In a steamy bathroom, those seals crack. It&rsquo;s almost inevitable. Once moisture sneaks in, the copper starts to oxidize and the insulation wears thin. We call this thermal aging. Eventually, the electricity just jumps the gap—it arcs—and the whole thing pops.</p>
