Boiling water is a critical part of ensuring that it remains safe for consumption, as it removes numerous impurities and harmful bacteria that can be found in untreated or contaminated sources. Boiling water also makes it a great alternative to other methods of purifying, such as filtration or chemical means, because simply getting the water to a rolling boil is enough to render most pathogenic bacteria, viruses, and protozoa harmless.
However, boiling water without electricity can be difficult if you do not have access to the necessary resources – especially when electricity is out, or the stove is having some issues. Fortunately, there are various methods available to boil water without electricity, each with its own unique approach.
Some methods, like high-powered camping stoves and portable butane burners, can bring water to a boil in under five minutes, while others, such as the solar kettle, take a more relaxed pace.
Regardless of the method you choose, the end result is always the same – clean and palatable water that is safe to drink. In this post, we’ll explore a range of ways to heat water without electricity, including traditional fire pits, charcoal grills, solar cookers, and camping stoves, among others. With these methods, you’ll be able to enjoy hot drinks and meals, whether you’re out camping or facing a power outage.
Note: Boiled water can have a slightly flat flavor, but a pinch of salt can make it taste better and be more hydrating. Boiling water drives out the dissolved oxygen, which can make it taste flat. Adding a pinch of salt to boiling water helps to restore some of the flavors and also helps to regulate the body’s electrolyte balance which will help to keep the body hydrated and functioning properly.
1. Boil water over a fire pit
Heating water is easy when you know how to start a fire. Fire has been an essential survival tool for humans since the dawn of time. It’s also an incredibly simple way to heat water without electricity.
You can achieve a stable cooking surface without any additional equipment by balancing your pot, kettle, or even a survival canteen or bamboo cup on sticks or stones within the fire.
To do this, first, choose a safe location away from flammable materials. Then, gather some firewood, kindling, and a lighter or matches. Build a fire by making a pile of kindling in the center, then adding firewood around it. You will need to maintain the fire by adding wood as needed and wait for the coals to form. Finally, place your pot or kettle with water on the coals and wait for the water to boil.
If you are outside camping, don’t forget to practice fire safety and check for any fire restrictions before starting a campfire.
2. Use a Solar Cooker
Solar cookers are a great way to boil water without using any electricity. They work by using reflective material to concentrate the sun’s rays onto a pot of water, which heats it up and boils it.
To use a solar cooker, you can simply place it in direct sunlight and then put a pot of water in the center. Cover the pot with a lid and wait for the water to boil. It can take anywhere from 30 minutes to a few hours, depending on the strength of the sun and the size of the pot you’re using.
Once the water starts boiling, carefully remove the pot using an oven mitt to avoid burning your hands. Solar cookers are a great eco-friendly way to boil water, and they’re also very affordable. If you’re looking for a way to save energy and reduce your carbon footprint, a solar cooker is a great option.
Solar cookers can be found on Amazon, or you can DIY it by following this video:
3. Boil water using a rocket stove
Rocket stoves are efficient and portable devices that can easily boil water with just a small amount of wood fuel. To use a rocket stove, simply add your wood fuel to the fuel chamber and light it up. Then, place a container with water on top of the stove’s cooking surface. Once the water starts boiling, you can remove the container and enjoy your hot water.
If you’re interested in getting a rocket stove, you can find them at your local sporting goods and outdoor store or order them online. Alternatively, you can build your own rocket stove using various methods.
Building a rocket stove can be done using a variety of methods and materials, including a simple block of wood or metal with an L-shaped hole in the middle. You can see more about rocket stoves for camping.
4. Use a propane or butane camp stove
We often use gas stoves to boil water, so it can be an option that is easily accessible, especially if you want to reduce your electricity usage or go off-grid. A single-burner propane stove or a two-burner camp stove can be enough for boiling water, depending on how much you need to boil.
Butane stoves, such as the Coleman Portable Camoing Stove or Gas One GS-3400P, are also great for boiling water and tend to be more compact and portable, making them a convenient option if you are backpacking. These stoves can get water to a rolling boil in just a few minutes, allowing you to have drinkable water much faster than fire or a solar cooker.
To use a camp stove, turn it on and place a pot or kettle of water on top until it starts boiling. Once the water is boiled, remove the container and turn off the stove. You can find camp stoves at your local sporting goods and outdoor store or order them online. They’re a handy item to have, so you may want to keep one in your garage just in case you need it.
5. Boil water with candles
When you don’t have access to electricity or gas, boiling water with tea candles is a great way to make a cup of tea or coffee. You only need a mug or pot, water, tea candles, a metal or ceramic container, and a lighter or matches.
See some of the best tea candles from Amazon:
Once you have the equipment, fill the mug or pot with water, place about 10 to 15 tea candles on a ceramic container or a baking tray, and then place the container in the center of the mug or pot. Using a frying pan can make the process a bit faster. Then light the tea candles and ensure there are about 1-2 inches of space between the flame and the water container, and then wait for the water to boil.
The water will take about 10-15 minutes to boil, depending on the size of the mug or pot, the number of tea candles, and the ambient temperature. This method may not be the most efficient, but if you have tea candles, a baking tray, and a wide water container, you can easily heat water without electricity in a couple of minutes.
6. Use a solar oven
Boiling water inside a solar oven is similar to boiling water in a solar cooker. Both methods use the sun’s heat to boil water. However, a solar oven is more efficient than a solar cooker because it traps more of the sun’s heat.
Using a solar oven to boil water is super simple. Just fill a pot or kettle with water and place it inside the solar oven, making sure that the lid of the solar oven is closed tightly. Next, place the solar oven in a sunny spot and wait for the water to boil.
It will take about 2-4 hours for the water to boil, depending on the size of the solar oven, the amount of water, and the intensity of the sun. You will need to check the water periodically and add more water if it starts to boil away (in case required).
7. A solar kettle
Boiling water without electricity by harnessing the sun’s power can’t be more efficient than on a solar kettle. It uses a thermal vacuum tube to absorb and convert the sun’s energy into heat. Because it has a smaller surface area and better heat-absorbing material with exterior reflectors, which help to maximize the sun’s rays, solar kettles are faster in boiling water than other water boiling methods using solar power.
A solar kettle would still take around 45 minutes to boil water despite being the most efficient. They are perfect for survival situations, camping trips, or any other outdoor adventure without electricity or gas.
When using a solar kettle, placing it in direct sunlight is important to maximize its effectiveness. Additionally, you will need to monitor the water level and add more if necessary. And as always, take care when handling hot water.
The GoSun Sport is a high-quality portable solar kettle that can boil water a lot faster.
8. A portable power station can help boil water
A portable power station can be a great solution for heating water when you’re off the grid or experiencing a power outage. However, boiling water with a portable power station requires significant power and can quickly drain the battery.
To use a portable power station to boil water, you’ll need enough charge and a way to recharge the device, either with solar panels or a wall outlet. If you rely solely on the wall outlet, you will likely encounter the same problem.
Alternative methods like a gas stove, campfire, or solar kettle are more efficient than using your power station to boil water.
9. Heat Exchanger
To use a heat exchanger to boil water, you would need to connect the device to a hot fluid source, such as a boiler or a solar hot water system. The heat exchanger would then circulate the hot fluid through a series of tubes, while the water to be boiled is circulated in a separate set of tubes.
As the hot fluid passes through the tubes, it transfers its heat to the water, causing it to heat up and eventually boil. The heated water can then be collected and used for various purposes, such as cooking or cleaning.
Using a heat exchanger to boil water has several benefits. First, it can be more efficient and environmentally friendly than traditional methods like electric or gas stoves. Second, it allows you to use a renewable heat source, such as solar energy, which can be more cost-effective in the long run. Finally, using a heat exchanger can be safer than traditional stoves, as there is less risk of fire or burns.
10. A car kettle can boil water for you
When you are out of reach of electricity, boiling water using a car kettle designed to run on 12 volts can be another option. To use the car kettle, fill it with water and plug it into your car’s cigarette lighter socket. WTJMOV 12V Car Electric Kettle and SUNSBELL 12v Car Kettle are some nice options you can go for.
Turn on the kettle and wait for the water to boil. The time it takes for the water to boil will vary based on the kettle’s wattage and the water’s temperature, and it could take up to 50 minutes for the water to boil in a car kettle. Once the water has boiled, you can unplug the kettle.
You should not leave the kettle unattended, forget about it while the water is boiling, and be cautious when handling hot water.
11. Geothermal Energy
Geothermal energy is a natural heat source generated by the earth’s hot interior. To harness this energy for boiling water, you must have a geothermal well or borehole or access to one nearby. Pumping water into the well and the heat from the earth’s interior will naturally heat the water. Once the water is hot enough, pump it back to the surface and use it for boiling or other purposes.
Using geothermal energy to heat water has several benefits. It’s a sustainable and renewable energy source, which means it’s environmentally friendly and doesn’t produce harmful emissions or waste products.
It’s also cost-effective in the long run because although the initial installation costs can be high, the energy is free once the system is in place.
12. Solar Thermal Collector
Solar thermal collectors are devices that absorb heat from the sun and transfer it to a fluid like water. This fluid then passes through tubes, where it is heated up and can be used to boil water.
To use a solar thermal collector, you will need to set it up in an area with good sun exposure. The collector should be installed at an angle where it can receive maximum sunlight throughout the day. The fluid you want to heat, such as water, is pumped into the solar thermal collector.
As the sun’s rays hit the collector, the fluid inside is heated up and then circulated through a system of tubes. The heated fluid can then be used to boil water or for other purposes.
13. Solar Water Heater
Solar water heaters are designed to use the sun’s energy to heat water. There are many different types of solar water heaters, but they all have one thing in common: they circulate water through tubes that are exposed to sunlight, which heats up the water.
To use a solar water heater, you’ll need to have it installed in an area that gets plenty of sunlight, such as on a rooftop. Once it’s installed, the solar water heater will start collecting sunlight and heating up the water in the tubes. This hot water can then be circulated back into your home for use as hot water.
Summing up: Each of these methods to boil water without electricity has its unique advantages and disadvantages, and some require specific conditions or equipment. Choosing the right method depends on your location, available resources, and heating needs.
However, these methods offer sustainable and environmentally friendly alternatives to traditional electric water heating methods by harnessing renewable energy sources.
