Update: In the years since Xefro burst on the scene touting a revolutionary graphene-based solution for heating people’s homes, the company has accrued skepticism and lawsuits. According to a story published by the United Kingdom-based site, Mirror, a retired couple paid almost $10,000 to have Complete Energy Europe – Xefro’s sister company — install a cutting-edge graphene radiator system in their home but instead received “nine useless radiators, a malfunctioning control system, and no water heater.”

The couple was left without a proper way to heat their home and short $10,000. Unfortunately, Complete Energy Europe wasn’t answering its phones nor responding to emails when Mirror published its article. The firm’s postal address leads to an unrelated law firm, the article also points out.

Several other customers spoke out on the forum website A Spokesman Said, saying Complete Energy Europe failed to deliver on a promised heating system and is difficult, if not impossible, to get ahold of.

As Xefro’s website seems no longer active, we reached out to Complete Energy Europe for more information and will update the article if we hear back.

Original article: More people are looking for ways to cut back in energy usage in any way they can, especially after the frigid winter much of the U.S. just experienced. One U.K. startup may provide new options with graphene.

Xefro has created a graphene-based heating system that can reduce energy costs up to 70 percent, according to IEEE Spectrum. Furthermore, it can quickly switch on and off, thanks to graphene’s minimal thermal energy. The company claims that its product, known as gRAD, is the first of its kind to use graphene as a heating element.

Graphene is composed of a single layer of carbon atoms arranged in a honeycomb shape, making it thin yet incredibly strong. It has excellent properties as a heat conductor. The high surface area of graphene makes it perfect for emitting infrared. This means that it doesn’t need to generate a hot surface temperature in order to function, making it a safer option than a standard heater.

The company has a couple of products using graphene, the gRAD central heating system and the g2o hot water system. “The innovation is all about getting useable heat where it is needed,” Tim Harper, a founder of Xefro, tells IEEE. “By selecting the right materials for the construction of the heater, we can reduce absorption of infrared to the minimum and ensure that most of the heat is emitted (out into the room) rather than simply heating up the wall behind the heater.” Based on Xefro’s site, it looks like the gRAD hangs on the wall and is made of carbon fiber sheet, the graphene-printed IR element, a vertical tube array, and stain gloss or carbon fiber finish.

Xefro has also created a mobile app for you to use to control your products. The app is designed for smartphones tablets, desktop computers, and laptops (although no operating systems have been named just yet). “The energy savings come when the heaters are deployed as a system throughout a building,” says Harper. “The heaters are linked with the control system via Wi-Fi, allowing the system to learn your behavior as well as the optimum heating required to maintain a comfortable temperature.”

The heating system will be available starting in July 2015 in the U.K. but there are no pricing details. There will be further expansion to other markets later this year.

Update 10/28/24: This marks the beginning of our drill coverage for 2024's Black Friday shopping season, and all of the major brands have at least one great deal. While we're excited for what is to come, this is a fantastic start and there's really no reason to not go ahead and get prepped by buying something now.
If you're buying anything this Black Friday, there's a big chance you might want a drill/driver to go with it. A drill/driver is one part drill, one part (screw)driver and it can help out in many situations. For example, say you take part in one of these early Black Friday TV deals, you very well might want to wall mount it. Then, say you grab up an easy coffee maker from Keurig's early Black Friday deals. An extra side table in your study would sure go nice with that and a drill/driver could very well make the table's construction much easier.
Really, with so so many of your early Black Friday purchases, there might be a chance to pick up a cordless drill or driver and get to work. As such, we've compiled a list of the best cordless drill deals throughout Black Friday deals that are available now, so you can get a head start on prepping for the savings that are to come.
