Next-gen electric radiators powered by waste heat
Spotted: Data centres are a significant but often overlooked contributor to climate change, responsible – along with their accompanying data transmission networks – for around one per cent of global greenhouse gas emissions. Computer processes generate a lot of heat as a by-product, and cooling systems therefore account for a significant proportion of the energy consumption of a typical data centre.
Now, however, French startup Hestiia is looking at the heat generated by computing differently, using it to create a new kind of domestic radiator, called the myEko.
The startup collects and upgrades used ASIC chips from data centres and places them on a custom-made electronics board, which forms the core of the radiator. Conductive layers and piping then transfer the heat produced when the refurbished chips perform calculations to the space that needs heating.
Hestiia provides the compute capacity embodied in the radiators to companies that need it for heavy workloads such as scientific research, 3D modelling, crypto mining, and blockchain. The startup’s customers, meanwhile, install the radiators to heat their homes.
In addition to being highly efficient, the radiators use smart sensors to automatically regulate the temperature of a room, and users can tweak preferences on the app, such as setting day and night modes to automatically adjust temperatures for each space depending on the time of day. And, the system further detects temperature changes from actions such as opening a window and alerts owners, signalling them to turn the temperature down to avoid wasted energy. In ‘geolocation mode’, the system can detect when a user is coming home and turn on the heating accordingly.
Hestiia’s initial product was a water heater system called SATO that similarly reused the heat from computer chips to supplement a standard boiler. The startup is now pivoting to focus on myEko, which it believes is an even more accessible, mass-market solution.
Other innovations in Springwise’s library working to decarbonise computing include a new power distribution unit that maximises efficiency, and the use of AI to reduce the number of calculations required.

If you’ve been on social media any time in the last year, you’re bound to have seen a workstation sink. The multifunctional units are the envy of every avid home chef, and this version by Delta Faucet is terrific. Designed to meet the evolving needs of modern kitchens, the workstation sinks are a blend of Delta Faucet water-delivery expertise and functional design. Each Workstation sink is sleek in design and offers a multifunctional workspace through its built-in WorkFlow™ ledge. The adaptable sink space is equipped with integrated accessories like cutting boards, dish racks, utensil holders and even a ledge to hold your phone or tablet. Constructed from durable TRU16 gauge stainless steel and featuring noise-reducing soundproofing, these sinks are designed for both durability and quiet operation.
Often, the goal of technology is to increase functionality and make things easier, but sometimes, it’s about pure luxury, and that was Kohler’s goal when creating the Statement Shower Collection—exquisite design paired with innovative performance to create the ultimate well-being experience.
The average kitchen extractor or cooker hood has never been the most attractive of appliances. While they have a valid purpose in most homes, bulky, shiny and painfully noisy are but a few choice descriptives for the standard extraction system, and because of these unfortunate characteristics, these silver suckers have been rapidly falling out of favor with designers and homeowners alike. But what do you do when you have poor ventilation and a fondness for aromatic foods? The answer— downdraft extractors. A relatively new innovation in kitchen design, downdraft extractors offer a sleek and discreet alternative to traditional overhead cooker hoods. They’re designed to be flush with the kitchen countertop and extract air directly from the hob when in use, making them especially suitable for kitchen islands or where a clear line of sight is preferred.
A fridge is a fridge, right? Wrong! The 30-inch Column Refrigerator by Dacor is the epitome of refrigerator technology. Placing technology at the forefront, the innovative fridge boasts intuitive features such as the iQ Remove View, which allows users to control temperature and lighting remotely and even view the contents of their refrigerator to simplify grocery shopping and a hidden touch-control display panel regulates temperature, helping to preserve food freshness and extending the lifespan of your groceries.
There’s nothing quite like sitting in front of the fire on a cold winter’s evening, but the thought of cleaning it out and lighting it, alongside environmental concerns, can quickly take the romance out of the idea of having a fireplace in your home.
