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 appropriate for use with electric induction stovetops. It is of course also suitable for regular electric and gas stoves as well. You can also use it camping with butane, alcohol, and other stoves.

      How should I clean the Billyboil?

      You can clean the Billyboil like any stainless steel cookware. Use warm soapy water to clean the inner pot. For the outer pot, a quick wipe-down with a damp cloth is usually sufficient. Avoid using steel wool or abrasives as they may scratch the stainless steel. For any stubborn marks, use a stainless steel cleaner or cleaning paste, like Gumption.

      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.

      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.

      Billy boil works

      Cooked a mouthwatering corned silverside in there as my first trial. Pot is bigger than you think. Worked very well retaining extra flavours though out the meat. Will do that again. Can’t wait to go camping with it.

      After owning an earlier model of the Billy boil (which I prefer) and feel was more robust I feel this model may not last as long eg lid hinge which I feel may be the chillies heal, but hoping not.

      Hi Leonnie, The removable outer lid is handy for cleaning or when using the Billyboil as an insulated ice bucket. Just check that it's fully snapped back in when re-attaching. It's proved quite durable across several thousand customers using the current design.

      There are not enough recipes for this product, still learning.

      My Billyboil

      I have a Billyboil which was a gift. It is an excellent pot. I really enjoy using it and find it most successful. We needed a Thank You for someone who had done us a big favour so we purchased this Billyboil for them.

      Tony Kosovich

      Sorry, life has been busy here so we’ve only used it once, but l am very happy with our Billyboil. We purchased it for our motor home but we haven’t been away for a while.
