Conventional camp stoves have an efficiency rate of 40% — more than half of the energy is wasted! In response, we designed the PrimeTech Stove System to achieve an efficiency rate close to 80 percent.
Choosing a PrimeTech Stove System means:
1. You can bring less fuel with you
2. Less fuel is good for your wallet, your back and the environment
3. Your food will heat up/boil faster
"All of us who spend time in the great outdoors have one thing in common: we want hot meals as quickly and smoothly as possible." - Eric Svartström, Head of R&D
By combining three technologies: (1) a built-in heat exchanger in the pot, (2) an integrated windscreen that protects the flame, and (3) a burner optimized for the PrimeTech Pot, we achieved nearly double the efficiency of a normal camp stove. This increased efficiency means a 100g Primus gas canister is sufficient to cook every lunch and dinner, brew breakfast coffee (or tea), and still have enough fuel for afternoon fika* for one person during a five-day trip! Carry half fuel, produce half emissions.
*fika is a Swedish coffee break
"During the development of the super efficient stoves, we went back to the drawing board and reviewed every aspect of the stove: How do we make the burner, the windshield and the pot work optimally together? How do we get your LP gas to last almost twice as long, by reducing heat loss and heat-up time? Primus solved the challenges. Every PrimeTech stove now offers you an unsurpassed user experience for a long time onwards, at a maximized efficiency rate and at a minimal environmental impact." -Eric Svartström, Head of R&D
The yellow/red parts show areas where heat goes up past the sides of the pot rather than going in to the pot.
The yellow/red area is greatly reduced and this focused heat goes directly into the pot, while the blue shows how little heat is lost going up the sides.
