Billyboil cooks your food using retained heat, for up to 8 hours. There is no energy requirement after the initial heat-up phase. This means you can save up to 80% of your cooking energy usage!

For example, based on a typical use of 20 minutes total cooking time, there would be an initial 5 minute “heat up” phase, followed by a 15 minute “simmer” phase.  With Billyboil, the simmer phase, usually spent on the stovetop, now consumes zero energy.  That’s 15 minutes of energy savings!  Longer cooking times equal more energy savings.

Regardless of what type of cooktop you have – gas, electric, or induction, Billyboil works with all of them, and makes any cooking process more energy efficient.
