Experience the ingenuity of the Original Copper Thermette, a remarkable Kiwi invention conceived by John A. Hart in 1929.

Known by various names such as 'chuffer,' 'kelly kettle,' and 'Benghazi boiler,' the Thermette is an essential companion for outdoor enthusiasts. With the ability to boil water in just 2 minutes and cook meals in the wild, this versatile cooker relies solely on small sticks and twigs for fuel.

The Thermette's rapid water-boiling capability is attributed to its proven design, featuring a unique cone-shaped internal wall that efficiently distributes heat across a large surface area surrounded by water. Similar to a rocket stove, the heat is funneled from the bottom up through the top, simultaneously reaching the upper section for cooking meals in a pot or pan.

Bid farewell to the hassle of carrying or purchasing cooking fuel – simply gather dry twigs and ignite them with a lighter or matches.

A true outdoor companion, the Thermette accompanies me everywhere, facilitating the creation of wild infusions (wild herbal teas) and cooking meals during camping trips. Its lightweight design ensures easy portability, and it remains effective even on wet days.

The Thermette offers versatility – boil water in the body (in just 2 minutes!) or add the cooking ring on top to hold a pot and heat food or water simultaneously.

Each order includes:

  • 1 x Solid Copper Thermette
  • 1 x Cooking ring (for holding a pot on top)
  • 1 x Galvanized fire ring (placed at the bottom to create your fire)


  • Height – 38cm tall
  • Weight – 1.7kg
  • Water volume – 2.2 liters

This extraordinary Kiwi invention is so renowned that the New Zealand Army has been utilizing Thermettes (also known as chuffers) for years!

Copper Thermette

Excellent purchase and a quick, no hassle delivery. The Thermette boils water quickly and heats food easily. It is a great piece of kit to have on hand for camping, power cuts or during any natural disaster.

Amazingly fast

Love the thermette, I have only used it once to give it a test drive, but was amazed how a handful of twigs can get the water boiling so fast. By the time I got my second handful it was at boiling point. Just don't fill the water right up as it boils over and puts the fire out 😂

Although I haven't as yet used my Thermette, I am very happy and looking forward to using it in my garden. It is exactly the same as I remember my Dads thermette that we used camping and picnicing in my childhood. I am happy it is made of copper

Hi there, the thermette has been used a few times, with my families, when we are out & about. Fast & easy to boil water for cuppa tea/coffee/soups. Amazing appliance, just like the old days. It is truly awesome. It now sits beside my braizier, when I heat my out door bath tub, for hot drinks at night.

Boiled in 6 minutes

So simple yet so effective, the gas camping stove is redundant. Touch and go whether it can boil 2L faster than the electric jug too!
