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:

  1. A stainless steel inner pot to use on your stove, and
  2. A vacuum-insulated outer pot with a carry handle.

Billyboil Thermal Cooker Components

The Billyboil insulated thermal cooker components.

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.

Billyboil Thermal Cooking Process

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.

      Love it - first class for yoghurt making, directly in the pot. Veg stew, roo ragut, no fuss, no burnt bottom, minimal power used, easy clean up. Very happy.

      Billyboil is very good for camping!

      Billyboil has been so very useful in my mini campervan, as it takes minimal gas to bring a meal to the boil for a while. I then seal it up and enjoy the day! Late afternoon I undo it and have some of the delicious stew, and more at supper time. One of the good things about it is that the inner pot is very easy to clean if I wipe it out first and then wash it. The 3 ltr size does two adults a big meal, and to make a meal go further and be more warming I can add rice. The best thing I have bought for a long time. It is also good for taking food to my daughters house for lunch rather than buying junk food.

      Pleasing results

      Tried porridge and Mediterranean Chicken dishes so far. Both turned out quite well.

      Exceeds my expectations

      So happy with my Billyboil. Took it camping and first night I ate a fantastic Beef Stroganoff. Was hot, tasty, and the beef was tender. The next meal was a Chicken Curry. Absolutely delicious. Best Winter camping cooker ever. Love it. I'm going to try corned beef next.

      Great for caravans

      I use a portable induction cooktop in my campervan, and as power is limited the Billyboil is great to save power, as once the food is heated through you put it away and it continues to cook at no expense. It seems really well made, and after 6 hours the food was still piping hot, even after my wife opened it up once to check on it.

      Billyboil wonder

      Love my new Billyboil Thermal cooker, it works a treat. I haven't used it out on the road yet but have tried it at home. Made a beef casserole and everything was cooked perfectly, left it for 6 hours, it was warm enough to eat but I did heat it up again for 5 mins to thicken the sauce. Very easy clean up.
      I ordered it on a Wednesday and it was delivered the very next day.
      I'm very impressed, would love some specific recipes though.

      It works just as it is advertised it's fantastic
