Save Time & Energy While You Cook
The Billyboil uses no energy after an initial heat-up on your existing stovetop. It cooks delicious meals for up to twelve hours using retained heat.
It's an ideal solution for everyday cooking or when you're travelling. Here's why:
- It saves time because you can leave your meal to cook unattended while you do something else.
- It saves money using up to 80% less energy than conventional cooking methods.
- It's vacuum insulated, which means it can keep food cooking between 60˚C and 100˚C for up to 12 hours.
- It's safe and easy to use, with a carry handle and lockable lid for travel.

How Does the Billyboil Work?
The Billyboil has two main parts: a stainless steel 'inner pot' and a vacuum-insulated 'outer pot'. Here's how easy it is to use:
- Use the inner pot like usual: bring your food to a boil, or cook as your recipe requires.
- Once the food is heated, switch off your stove, place the inner pot inside the outer pot, and close the lid. The Billyboil will continue to cook the food using retained thermal energy in the already heated-up food.
- Remove the inner pot when the cooking time has elapsed or when you're ready to eat (up to 12 hours later).
The Billyboil is easy to use on any existing stovetop.

Frequently Asked Questions
How many people is it suited for?
This thermal cooker has an internal capacity of about 4.5 litres. It suits cooking for four or more people. You can also use it for cooking in larger batches (for a smaller number of people) to make extra meals for later.
If you prefer something a bit smaller, see our compact 3L thermal cooker.
Some of our customers buy one of each size for large groups or for cooking two types of food (for example, rice in one and a curry in the other).
What recipes do you suggest?
Any recipe designed for extended simmering, slow cooking, or one-pot cooking is ideal for the Billyboil.
In other words, you probably already have a stack of suitable recipes. We have more guidance in the instruction manual (in the specs table above) and this thermal cooker recipe guide.
Is it compatible with electric induction stovetops?
Yes. It has a thick base which is appropriate for induction stovetops. It even works on camp stoves, butane stoves, alcohol stoves, etc. It is, of course, also suitable for regular electric, ceramic, natural gas, and LPG stoves.
How should I clean the Billyboil?
You can clean the Billyboil's inner pot like other stainless steel cookware. Use warm, soapy water - or put it in the dishwasher. For any stubborn marks, use a stainless steel cleaning paste, like 'Gumption,' with a non-scratch scourer.
A quick wipe-down with a damp cloth is usually sufficient for the outer pot.
