Boiling Billy applies the Venturi Principle of water pressure. There aren't any moving parts so it's maintenance free. It's our way of harnessing nature's technology. When there aren't any pumps, solenoid valves or electronic taps, there are fewer breakdowns and, importantly, less energy is consumed.
Our heating element contains its own small electronic control unit so it's easily replaced when it eventually does wear out. Everything else is recyclable. That means only 2% of our product ends up as landfill.
