Make safe drinking water on the StoveTec rocket stove with our water pasteurizer! A quality pasteurizer is not just important for the 50% of the developing world that cooks on an open fire daily and pasteurizes every sip of water they drink to stay alive. Safe drinking water is important for emergency and recreation use for everyone. A water pasteurizer one of the prepper’s most important emergency supplies. Stovetec’s pasteurizer features a water pasteurization indicator (WAPI) with every unit.
To verify pasteurization, remove the water reservoir fill cap and hold in the vertical position to inspect the pasteurization indicator tube. Verify the red indicator wax has liquefied and dropped to bottom of pasteurization indicator tube. This indicates water has reached pasteurization temperature and is now safe to drink!
After verification of water pasteurization, simply turn the WAPI assembly upside down and place assembly on the flat top of the knob. The indicator wax will flow down tube and solidify quickly for years of repeated use.
In many countries fuel sources are minimal, wasting fuel to bring water up an additional 62 degrees to boiling is not required. The beauty of the WAPI modification is that the capillary tube is filled with red soy wax that melts after 5 minutes at 160 degrees, and the red wax falls to the bottom of the tube. Note that there is an additional 10 degrees of safety margin built in this low tech, low cost solution.
This product is designed to maximize surface area and optimize heat transfer from the inside out. Note the hollow inverted conical shape specifically designed for use with our rocket stove. Water is poured into the inverted conical walls of the pasteurizer, brought to temperature, and then allowed to quickly cool when removed from the stove. No other product enables you to make 4 liters of safe water as quickly and inexpensively as this pasteurizer with very little fuel.
Paired with a StoveTec rocket stove, approximately 4 liters of water can be brought up to 65°C (149º F), the temperature required to pasteurize water in mere minutes. The volume of a well-designed pasteurizer is important. Stovetec’s 4-liter volume of water is an effective individual amount to have on hand for an emergency drinking supply, to cook a pot of noodles, soup, or sanitize your cookware.
The pasteurizer container body is lightweight stainless steel alloy; the cast aluminum spout is mounted above the water line. Note: Do not fill pasteurizer above the water line below the spout. Overfilling the pasteurizer can cause excess heated water to jet from spout. An overfilled pasteurizer can cause burns. The small water cap is an additional safety feature to prevent toddlers from being burned by preventing them from sticking their hands inside the pasteurizer.
Water pasteurization is the heat process used to kill harmful bacteria and make water safe to drink for human consumption. Most people have heard to boil water to make it safe to drink. That made sense because boiling was one of the only visual indicators that medical authorities could explain to people that they could verify. The fact is that boiling is reached at 212 degrees and pasteurization occurs at approximately 150 degrees after 5 minutes.
The dairy industry developed flash pasteurization and really developed pasteurization science. Heating water to 65º C (149º F) will kill all germs, viruses, and parasites. Pasteurization can be accomplished without having to bring the water to a boil. There is no water filtration system included with this product. Heavy metal or water contaminated by toxins is not affected by the pasteurization. Pasteurization will not help if water is brackish or chemically contaminated.

Question: Many Western societies concerned about aluminum pots and possible links to Alzheimer’s disease.
Answer: The cast aluminum spout is located above the water line. Interestingly, in the 3rd world where cheap aluminum pots are almost exclusively in use, Alzheimer’s disease is almost non-existent, unlike the West.
Question: What is the Chinese kanji on the top of the pasteurizer.
Answer: “Welcome”. These water pasteurizers are seen throughout China (outside shops, construction sites, etc.). Customers and workers are invited to help themselves to hot water to pour into their personal tea containers. There is a wonderful sense of community in regard to the use of these pasteurizers throughout China.
Question: What are the holes for at the bottom of the pasteurizer base?
Answer: Ventilation. The ventilation holes at the bottom of the base are required if not using the pasteurizer on top of our stove. This application allows you to pasteurize water by placing the pasteurizer directly on top of a small fire and the ground, although this technique is not as efficient as using the Stovetec stove. Any of the 6 different models of our StoveTec rocket stoves offer more efficient heat transfer, reduce fuel use, smoke, and emissions by using the pasteurizer directly on top of our stove (not included).
