This Football-Sized Device Could Replace Your Huge Water Heater

That tank of hot water in your backyard eats up a lot of energy. But tankless on-demand water heaters leave you running water down the drain while you wait for warmth. This tiny Kickstarter water heater promises to change all that, and save you money, thanks to some fascinating technology.

The team behind the Heatworks Model 1 says the 30cm-long device can deliver instantaneous hot water on demand, saving 40 per cent on energy costs and 10 per cent on wasted water compared to an electric tank-style heater. One unit supplies enough endless hot water for one shower at a time, while larger households could install a unit at every bathroom, saving money on hot water piping and cutting out minutes spent waiting for hot water to arrive. The key is how the Model 1 heats the water. Unlike current tankless electric heaters, which use a corrosion- and failure-prone metal coil, Heatworks relies on submerged graphite electrodes that use the water around them as a resistor. This, they say, gives you instant heat, rather than the 30-second wait associated with other tankless systems.

Sure, this all sounds great, and with the Kickstarter already past goal, it looks like Heatworks will have the money they're seeking to start production. But being funded on Kickstarter is entirely different from producing a reliable product in quantity. Even if they make it, are you willing to trade the familiar water heater any plumber can fix in the middle of the night for a high-tech energy saver that runs on the future? It's a gamble, and a cold shower is the loser's lot. [Kickstarter]
