From November 13 through December 10, Boldr is offering up to 30% off its Kelvin smart infrared heater with the code EARLYBLACK. It’s sleek, silent, and far more efficient than your average space heater. The Kelvin smart infrared heater offers sun-like warmth alongside real-time energy insights and integrates into your new or existing smart home setup.

Why Kelvin stands out

Save yourself from the clunky fan heaters and outdated baseboard heaters. Kelvin uses infrared technology to warm people and objects directly, just like the brilliant feeling of stepping into the warm sunlight. This heater delivers faster comfort, quieter operation, and lower energy use. And because it doesn’t rely on airflow, it won’t stir up dust. You can place it in a nursery or around allergy-sensitive people without a worry.

Installation is simple: mount the panel on a wall, plug it into a standard outlet, and pair it with the Boldr Energy app. From there, you can set custom heating schedules for each room, monitor your real-time energy use, or even ask Siri or Alexa to warm up the guest room. It’s the first heater in the U.S. with native support for Matter and Apple HomeKit, adding more connectivity to your digital lifestyle.

Kelvin is also designed to blend in. It has a minimalist aluminum-and-glass build that comes in black or white, with a low-profile form that’s easy to tuck into almost any space.

Who Kelvin is perfect for

  • Renters or homeowners looking for efficient, portable heating without complex installation
  • Smart home users who want Matter, HomeKit, or Alexa integration
  • Remote workers or visiting parents seeking a silent, allergy-friendly heater
  • Anyone with a drafty office, guest room, garage, or basement that never gets quite warm enough

Get it while it’s hot (literally)

With winter looming, don’t wait for a polar vortex or nor’easter to roll through. Now’s the time to avoid the scramble and make your space warmer. Use the code EARLYBLACK to score up to 30% off the Kelvin smart infrared heater through December 10. This deal includes free shipping, but it will not be around forever — and if last year’s sellout is any clue, you’ll want to act fast.

Robot vacuums are supposed to clean the house. Turns out this one was mapping it for strangers. Security researchers have disclosed a critical vulnerability affecting SharkNinja's cloud-connected robot vacuums that could allow attackers to remotely access sensitive information, including live camera feeds, home maps, Wi-Fi passwords, and even execute commands on affected devices. More concerningly, the issue reportedly remains unpatched despite being responsibly disclosed to SharkNinja months ago.
