Save Time & Energy While You Cook
The Billyboil uses no energy after an initial heat-up on your existing stovetop. It cooks delicious meals for up to twelve hours using retained heat.
It's an ideal solution for everyday cooking or when you're travelling. Here's why:
- It saves time because you can leave your meal to cook unattended while you do something else.
- It saves money using up to 80% less energy than conventional cooking methods.
- It's vacuum insulated, which means it can keep food cooking between 60˚C and 100˚C for up to 12 hours.
- It's safe and easy to use, with a carry handle and lockable lid for travel.

How Does the Billyboil Work?
The Billyboil has two main parts: a stainless steel 'inner pot' and a vacuum-insulated 'outer pot'. Here's how easy it is to use:
- Use the inner pot like usual: bring your food to a boil, or cook as your recipe requires.
- Once the food is heated, switch off your stove, place the inner pot inside the outer pot, and close the lid. The Billyboil will continue to cook the food using retained thermal energy in the already heated-up food.
- Remove the inner pot when the cooking time has elapsed or when you're ready to eat (up to 12 hours later).
The Billyboil is easy to use on any existing stovetop.

Frequently Asked Questions
How many people is it suited for?
This thermal cooker has an internal capacity of about 4.5 litres. It suits cooking for four or more people. You can also use it for cooking in larger batches (for a smaller number of people) to make extra meals for later.
If you prefer something a bit smaller, see our compact 3L thermal cooker.
Some of our customers buy one of each size for large groups or for cooking two types of food (for example, rice in one and a curry in the other).
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. We have more guidance in the instruction manual (in the specs table above) and this thermal cooker recipe guide.
Is it compatible with electric induction stovetops?
Yes. It has a thick base which is appropriate for induction stovetops. It even works on camp stoves, butane stoves, alcohol stoves, etc. It is, of course, also suitable for regular electric, ceramic, natural gas, and LPG stoves.
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.
Customer Reviews
I'm happy to review this product! We can now use less energy and save money on gas. Also we can cook on the fire (rocket stove and indoor wood stove) with much more ease because we can cook for a short time while the fire is hot and then pack the Billy boil away and let it finish cooking by itself, long after the fire has cooled down. + the meal is hot and ready to serve when we are ready to eat. If we aren't cooking anything we can just heat water on the fire and put it away to use the next day for dish-washing or cooking! (it was about 70 degrees C after 10-11 hours) It is well built with little design details that make it easy to use like the handle that stays up away from the heat while cooking and then folds away snugly later. Also the pots are narrow and tall making it easy to fit two at the same time on our small wood stove. Risotto worked well and I only had to bring it to boil, and then pack away, veggies still have their texture and have flavor all the way through. Stewed fruit was delicious, each piece of fruit still has it's shape unlike when boiled on the stove and spices and flavor all the way through the fruit. Yum. We'll be using this for years to come. Thanks
Loving the billyboil
I have both the 3 L and 4.5L. I have cooked Thai green curry in the 4.5L and brown basmati in the 3L. Both came out piping hot. This is my way of cutting down on energy usage
It is an excellent product that I like it very much. I used it every time whenever I need to. Very happy with it, The shopping experience with Reduction Revolution is excellent as well.
Just what I was looking for to save on energy usage in the caravan. Very pleased with purchase though could have got away with the 3L to just cook for 1 or 2 people.
Have used Bilkyboil twice and love it. Silverside and Chicken Caserol. Both turned out great. Love the product and great service. Thank you. Colleen.
I'm still scratching my head on how this actually does what it does. Stews comes out perfect, the veges are still firm and the meat couldn't be any more tender , yet everything is thrown together in the same pot at the same time. Boil for 15 or so minutes, lock it away and come back up to 6 or 7 hrs later and it's cooked to perfection and piping hot . Stew in 1 pot and my rice in the smaller pot . Easiest cooking I've ever done. Love it and will be using a lot ..
First thing I cooked was corn beef. So easy. No 6 hrs on heat in the slow cooker!! I live in the far north. According to the critics it was the best corned beef in history. Stews just as good. Anybody tries to take my Billyboil will lose an arm!
I have tee we I of these and use both at home and when camping. Such a great way to slow cook without worry about leaving appliance on
To small and way over priced
