MODEL 3 Smart Water Heater

![MODEL 3 smart water heater](https://static.time.com/v3/assets/bltea6093859af6183b/blt7a8d5ab70280723e/69893ef2fb4eac6ba2898336/model-3-smart-water-heater-best-inventions-2018-43.jpg?branch=production&width=1200&quality=75&auto=webp&crop=3:2)

Most water heaters consume massive amounts of power, ratcheting up families’ energy bills in the process. The designers at [Heatworks](https://myheatworks.com/pages/model-3-specs) are looking to fix that with the MODEL 3 Smart Water Heater. Unlike other heaters, which heat water in a tank using metal components, the MODEL 3 sends electrical current through the water, heating it up quickly and only when residents actually need it. Using a companion app, owners can also track their water usage, set a maximum temperature and even limit shower times, further helping to curtail costs. At $799, the MODEL 3 is more expensive than many other water heaters, but the energy savings may well add up fast: Heatworks estimates that the device will save the average family of four $240 a year. _—Justin Worland_
