Vacuum Insulated, Compact Thermal Cooking
The Billyboil Thermal Cooker cooks your food using retained heat for up to 12 hours.
It uses no energy after the initial heat-up phase on your existing stovetop. This means you can save up to 80% of your cooking energy usage!
The Billyboil has two main parts, which you can see in the graphic below:
- A stainless steel inner pot to use on your stove, and
- A vacuum-insulated outer pot with a carry handle.

This compact thermal cooker has an internal capacity of about 3 litres. It suits cooking for small groups of up to three people. You can also use it for cooking side dishes like rice, potatoes, or pasta for a larger group.

It's Like a Thermos Pot for Cooking
The Billyboil has a double-wall, vacuum-insulated outer pot. This means it is exceptionally good at retaining heat. It retains heat at least 50% better than our previous model Billyboil (sold between 2015 and 2020).
Here's how easy the Billyboil is to use:
Step 1 - Use the stainless steel inner pot as you would normally. Bring your food to the boil, or cook as required.
Step 2 - Once the food is heated through, switch off your stove. Then, place the inner pot inside the insulated outer pot and close the lid. The Billyboil will continue to cook the food using the retained thermal energy in the already heated-up food.
Step 3 - Remove the inner pot when the cooking time has elapsed, or up to 12 hours later, when you're ready to eat.
The Billyboil is easy to use on any existing stovetop.
Billyboil Thermal Cooker Benefits
The thermal cooker concept was developed for those travelling in caravans, motor-homes or when camping.
However, thermal cooking is an ideal solution for everyday cooking in the home. Here's why:
- Time-Saving. No boiling-over and no burning of food possible. Let your food keep cooking safely and unattended while you get on with something else.
- Energy Saving. Zero energy consumption after the initial heat-up phase on your regular stove.
- High Performance. It keeps food cooking above 60˚C for up to 12 hours. This is 50% longer than other thermal cookers on the market.
- Versatile. Use it to cook vegetables, curries, stews, or just about anything.
- Compatible. Suitable to use in conjunction with any stovetop (gas, electric, induction or even camp stoves).
- Safe. The lid can be locked closed with the handle for safe travelling. This also minimises any spillage if the Billyboil is knocked over.
- Removable Lid. The lid can be clipped off to keep your food piping hot at the table whilst serving. With the cover off, you can even use the Billyboil as an insulated ice bucket for super-chilled drinks.

Frequently Asked Questions
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. Here's a blog post we wrote about thermal cooker recipes.
Is it compatible with all stovetops?
Yes. It even has a thick base, which is necessary for electric induction stovetops. It is also suitable for regular electric hotplates, ceramic cooktops, natural gas burners, LPG stoves, etc. You can even use it when camping with butane, alcohol, and other fuels.
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.
