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.

      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.

      Lynne Guthridge

      Our first meal was beef in red wine sauce. Best ever. Absolutely love this pot.

      Billyboil 3lt

      Great product. Used three times already with great results. Heat retention great after eight hours. Happy we got this one and not a more expensive brand. Get 3 to 4 meals from full pot. A winner for us

      Better than a slow cooker

      I tried making a hay box years ago but it was too big for the house. This does the same job only more compact. I had a slow cooker which I gave away because I didn't have the room for it.

      As good as it gets

      I’ve only used my new pot twice but both times have been blown away by the results! Terrific meals and can’t wait to take it with us on our big camping trip starting next month. The BillyBoil will be invaluable

      Great little item

      Have cooked a couple of things and all turned out well. The real test is coming up when we go on the road very soon looking forward to pulling up and having the dinner sorted.
