Designed and produced by Erif, the innovative device does not require electricity and relies on a [battery-sparked igniter](https://www.trendhunter.com/trends/copper-charlie) instead. Running off two LPD canisters, the Outdoor Gas Boiler has neither a power button nor an ignition switch. The easy-to-use boiler boasts a [showerhead switch](https://www.trendhunter.com/trends/heau-shower), which users can push down to begin the boiling process. Once the flow of water is detected from the tap, the machine ignites automatically. The boiling process is fast, taking only 10 to 30 seconds to heat the water to 30 degrees celsius. On the exterior, the tankless water heater boasts a dial that switches between hot and cold temperatures for the user's convenience.
