Not much innovation is happening in kitchen appliances nowadays (unless you want wifi connectivity, voice assistant integration or the addition of a unecession screen). That’s why Heatworks’ Tetra countertop dishwasher requiring no plumbing was so exciting when it was first announced… in 2018. Three years later, you can finally preorder one, but the wait isn’t over yet.
Space-saving countertop dishwashers aren’t a new idea, but they’re often more of a hassle than they’re worth, requiring a kitchen faucet to be upgraded with an adapter so that a hot water supply hose can be temporarily plugged in every time you’ve got the dishes to clean. . The Heatworks Tetra eliminates plumbing connections and hoses with a 3-liter water tank that you fill and empty every time you wash a load of dishes – about three sets of plates, cups and cutlery. If you live alone or have a very small family, the Tetra will use less water and power than washing both a large dishwasher and a small number of dishes by hand and rinsing in the sink.
AAll you need to do is free up space on a flat surface such as a counter or table and plug in the dishwasher, but minimal installation requirements are not the only attraction of the Tetra. To heat the water in the reservoir, the dishwasher uses Heatworks’ innovative Ohmic Array technology. Instead of passing current through a submerged heating element that then inefficiently transfers heat energy to water, the Tetra works more like a microwave. Graphite electrodes direct a current through water to excite the minerals it contains, causing the water’s temperature to rise almost instantly. It is a more energyefficient approach, and the technology can accurately control the water temperature all the time. Traditional dishwashers have no way of heating water because instead, they often get it from a house’s gas-fired water heater, but ideally we should all try that reduce our dependence on natural gas also.
Heatworks claims that the Tetra “cleans 50% more dishes with 40% less water in 55% of the time than the leading brand of dishwasher”, but that also depends on how often and how full you use your dishwasher. The shortest cleaning cycle takes less than an hour to clean and dry dishes, while the standard mode pushes the cycle up to just over an hour before everything is ready for storage. It’s not as fast as the 10-minute wash cycle originally touted along with the dishwasher a few years ago, but its compact size and minimal water consumption undoubtedly still have an advantage if you live alone or with a single roommate. Heatworks promises the Tetra can be used for other purposes too given how accurately it can control water temperature, such as sterilizing baby bottles and children’s toys, washing clothes, or even cooking foods like fish. Be careful in which order you do all those things.
The Tetra is finally available for preorder today from The Heatworks website for $400, but that’s a discounted price for early birds; the full sale price will be $500. It’s definitely a more expensive alternative to existing countertop dishwashers that usually cost closer to $300, and you’ll have to factor in the cost of Tetra’s proprietary detergent cartridges, at. While Heatworks promises the cartridges contain concentrated cleaners to help reduce packaging waste and allow the machine to create custom mixes of soap and rinse aid on-the-fly for optimal cleaning, after about 20 or so, you’ll still need to order replacements directly from the company. loads.
The price will be about 30 cents per wash, or about $6 per cartridge, which is slightly more expensive than buying a bulk container of dishwasher tablets. A companion app provides advanced reminders when the current cartridge is running low, so that users can easily redoorder replacements, but as anyone who struggles with inkjet printers and ink cartridges knows, there’s always the chance you’ll run out of detergent at the wrong time, and you can’t just run to the grocery store to get some. That might be a deal breaker for some, but for those who don’t have room for a full-sized dishwasher in their kitchen, removing washing dishes from the daily to-do list can be a minor inconvenience.
