Start cooking for free with retained heat

The Billyboil Thermal Cooker cooks your food using retained heat, for up to 8 hours.

There is no energy requirement after the initial heat-up phase on your existing stove top. This means you can save up to 80% of your cooking energy usage!

The Billyboil Thermal Cooker has an internal capacity of 3.5 litres which is enough to cook for up to six people. It is made up of a stainless steel inner pot (roughly 20cm wide and 14cm high) and an insulated outer pot with carry handle.

A slow cooker, without the energy consumption

Slow cookers are great because:

  • They lessen the chance of food burning or boiling-over,
  • They allow for better distribution of flavours,
  • They can save time with 'one pot' cooking.

BUT regular slow cookers still need a continuous supply of energy, just like regular stove-top cooking.

If you enjoy the benefits of a slow cooker but want a simple, yet highly energy efficient cooking solution, then the Billyboil Thermal Cooker is for you.

Here's how the Thermal Cooker works:

Step 1 - Use the stainless steel pot just like you would normally, bringing your food to the boil, or heating-up as required.

Step 2 - Rather than leaving it on the stove-top for the required cooking time, you can now switch off your stove and place the 'inner pot' inside the insulated 'outer pot' and close the lid. The Billyboil Thermal Cooker will continue to cook the food for several hours using the retained thermal energy in the already heated-up food.

Step 3 - Remove the inner pot from the unit when the cooking time has elapsed or later, when you're ready to eat.

Thermal Cooker Benefits

The Thermal Cooker concept was originally developed for those travelling in caravans, motor-homes or when camping.

We think it's an ideal solution for everyday cooking in the home. Here's why: 

  • No boiling-over and no burning of food possible.
  • Zero energy consumption after the initial heat-up phase which you do on your regular stove.
  • Keeps food at safe (high) temperatures for up to 8 hours.
  • Use it to cook vegetables, curries, stews, or just about anything.
  • Works well as a rice cooker.
  • Saves up to 80% of your cooking energy costs.
  • Suitable to be used in conjunction with any stove top (gas, electric or induction).

    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 available.

    Here's a blog post we wrote on how to turn any recipe into a thermal cooker recipe. Additionally, there is a list of a few thermal cooker recipes on the Billyboil website. 

    Will it cook brown rice / arborio risotto rice / etc?

    Yes. The Billyboil Thermal Cooker easily cooks pretty much anything with 'absorption method' instructions on the back (all types of rice, risotto, etc). Simply use the same amounts as in the instructions, heat it up on the stove, then place it in the Billyboil to do the absorbing and cooking!

    Is it compatible with electric induction stove tops?

    Yes. It has a thick base which is appropriate for induction stove tops. It is of course also suitable for regular electric and gas stoves as well.

    Can I use it with camp stoves / alcohol stoves / etc?


    How should I clean it?

    Inner pot: Use your dishwasher, or wash it just like a normal saucepan with warm soapy water. Avoid using steel wool pads, or abrasives that may scratch the stainless steel surface.

    Outer pot: Wipe with a damp cloth only, then dry with a clean towel. Do not rinse or immerse the outer pot in water.

    Did you know? The Billyboil Thermal Cooker is easier to clean than regular saucepans because it is virtually impossible to burn your food to the bottom.

    How to test the performance of your Billyboil Thermal Cooker

    If you are having any trouble using the Thermal Cooker we suggest you conduct the following test to check and verify its performance.

    • Place 2 litres of water in the inner pot, bring it to the boil, and let it boil for a few minutes.
    • Then place the inner pot inside the outer pot, close both lids, and leave for 8 hours.
    • Open after 8 hours and measure the temperature of the water with a thermometer - it should be around 60˚C.

    If your thermal cooker is not performing as expected, please let us know.
