Towel heating element doesn't usually last all winter.
We built a master bath in late 2021, and got the Marquis Electric towel warmer. I was surprised when it arrived, because instead of being filled with glycol or mineral oil it's filled with plain water. No fear of galvanic corrosion or boiling of the heat transfer fluid, apparently. But ok, it's a towel warmer so the temp should not be high enough for the relatively low boiling point of water to be an issue.. or so I thought. Since the original install, I have purchased 3 replacement heating elements from Hudson Reed. Each one has failed after a bit over a year. The internal resistance of the element spikes; instead of its normal ~6 Ohms it will start overheating, reaching 180-200 F, then suddenly stop heating at all, permanently, with the resistance now measuring in the kOhm range, sufficiently high that no heat is produced. All show a solid patina of oxidation on the steel case of the heating element, and all have a tell-tale spot of intense corrosion just below the threads, where the whip is bonded to the heating element, sealed beneath a (now-rusted) weld. Posting this because as of tonight it looks like I need to buy another heating element.
