Thermos RPC-6000 6L Thermal Cooker

Thermos Thermal Cooker RPC-6000W 2x3L Thermo Pot

RPC-6000 thermal cooker with two 3L inner pots

Thermos also offers the RPC-6000 in a two 3L inner pot configuration which adds to the versatility of this thermal cooker. You are able to cook two recipes at the same time for example, rice and beans, rice and curry etc. or fill them both up with the same recipe for double the amount.  I’ve also used it with just a single 3L pot to cook smaller portions and filled up the empty space inside the outer pot with a small blanket, towel or rag to help retain the heat better.

Assemble all the ingredients in the inner pot, put it on the stove and bring to a boil. Then remove the inner pot from the stove and place it inside the outer pot which serves as a vacuum insulated container to keep the contents hot.  There is no need to plug in any power cord.  The food will continue its “thermal cooking process” using the retained heat.  After the required time (e.g. rice 30 min; chicken stock 2 hrs; beef brisket 3.5 hrs), just open the outer pot, and a nutritional and flavorful meal is hot and ready. The Thermal Cooker has excellent heat retention capacity; the food inside the pot can retain a temperature of about 160 degree Fahrenheit even after 6 hours.


Safe: It is not a pressure cooker, there are no power cords, no switches or electrical hazards to worry about.

Energy Saving: After the food has been boiled for a short time, the cooker needs no external energy while thermal cooking. Food stays warm automatically after it’s ready.

Convenience: The thermal cooking process requires no further supervision or monitoring. Food can be cooked while you are traveling. You can cook with the pot anywhere, anytime and it’s safe to use indoors or out.

Economical: Decreases fuel costs, economizes time and energy.

Healthy: Entraps flavor, minerals and vitamins; generate less odor, grease and smoke in the kitchen.

User friendly: Never over cooks and cleans up easily.

Durable: Unlike foam insulation used in other brands, Thermos’s vacuum insulated outer pot is a technology that foam insulation can’t begin to touch. Thermos produces the most effective insulated container and is engineered to last.

How does a Thermal Cooker work?

Thermal cooker is a patented product of Thermos®. It is an epoch-making cooking concept, consisting of an inner pot and outer vacuum insulated container. The inner pot is a three layers structure: two layers of stainless steel with a layer of carbon steel of high heat conductivity. It is able to conduct and absorb heat quickly. The outer container is vacuum insulated. It prevents heat loss and is able to keep warm and keep cool efficiently. The cooking process is easy and safe.

If you compare a thermal cooker vs a slow cooker you get the same functionality but without the power requirements. A thermal cooker is like a non-electric crock pot, you apply all the heat up front to the food while simmering on the stove and afterwards the recipe finishes cooking in it’s own heat.

Does a thermal cooker work? Absolutely! With two vacuum thermal cookers you could prepare your whole days meals in the morning. One would be ready to eat at lunch and the other still hot and ready to eat for dinner.
