This Much-Hyped Wall Heater Might Save You Energy. But It Has a Fatal Flaw
"The Kelvin looks a bit like a TV without a border, or the monolith in Stanley Kubrick's 2001: A Space Odyssey. Instead of driving apes crazy, this particular monolith emits far-infrared heat (a type of radiant energy) that its maker promises will make me feel toasty-warm while consuming a fraction of the power of a standard heater. Unlike resistance heaters with fans, it's blessedly silent. And there's an app that tracks basically everything, from room temp to energy use."
"In the usually hype-free world of space heaters, a trail of influencers and review outlets have hailed the $400 flagship device from Boldr-an international tech startup incorporated in London and with founders in Lithuania and Brazil-as the "smartest heater you'll ever own," a piece of "modern wall art" that makes traditional heaters seem obsolete, and a "seriously great" solution to your house's one cold room."
"While it's certainly the most interesting heater to pass my desk in the past year, I've had a much more troubled relationship with the Kelvin. This has been true since I tested the first-generation device last spring. Boldr's app remains a work in progress, the heater's use case is narrow, and the panel kicks a surprising amount of heat back to the wall you hang"
The Boldr Kelvin is a wall-mounted mirrored panel heater about three feet across that emits far-infrared radiant heat and consumes far less power than conventional resistance heaters. The panel provides gentle, even, and silent warmth and includes a smart-home app for temperature and energy monitoring with extensive customization. The device sells for about $400 and is positioned as modern wall art. The heater struggles to raise ambient air temperature quickly, occupies significant wall space, and reaches very high surface temperatures on its front and mounting crossbars. The panel also redirects a surprising amount of heat back into the wall.
