Can You Boil Water on a Grill?

It seems like a convenient option to use the grill for boiling water, especially when you are outdoors, away from the kitchen, and with no electricity. However, before attempting to boil water on a grill, there are some limitations and potential hazards.

Firstly, it is important to note that boiling water on a grill is feasible but not the most efficient way. The grill is primarily designed for cooking food, not boiling water. It may also take longer to boil water on a grill than on a stove or an electric kettle.

Furthermore, boiling water on a grill can pose potential hazards. The hot surface of the grill can be dangerous, and you may risk burning yourself or accidentally spilling the boiling water. Taking extra precautions when using a grill for boiling water is essential.

Boiling Water on a Charcoal Grill

Charcoal grills are popular among grill enthusiasts for their distinct smoky flavor. However, boiling water on a charcoal grill can be challenging. They don’t have a consistent temperature like a stove or an electric kettle, which can affect the boiling time, especially for grills that don’t have a damper to control the heat.

How to Boil Water On a Charcoal Grill

Here are the steps to boil water on a charcoal grill:

Step 1: Prepare enough charcoal to cook your food and boil your water because it takes less effort than adding charcoal while grilling.

Step 2: Light the charcoal. If your grill has been lit before and is in use, you can skip this step. You can use a chimney starter to light the charcoal and avoid using lighter fluid, which can leave a chemical taste in the food or water. Fill the starter with charcoal, light a few pieces of paper under the chimney, and wait for hot charcoals.

Step 3: Once the charcoal is hot enough, spread it out on the grill. If you have a large grill, you can put the pot of water on one side of the grill and cook other items on the other. Make sure to put the pot on a sturdy surface and use heat-resistant gloves to move it. Remember to cover the pot with a lid to reduce the boiling time.

Step 4: Wait for the water to boil.

Boiling Water on a Gas Grill

Gas grills are a popular choice for many grill owners due to their convenience and ease of use. Boiling water on a gas grill is relatively simple, even more leisurely for grills with side burners. However, it will still take a long time to reach boiling point.

How to Boil Water On a Gas Grill

Here are the steps to boil water on a gas grill:

Step 1: Begin by filling a pot with water, leaving enough space for the water to expand as it heats up. Use a pot with a lid to reduce the boiling time and prevent the water from spilling over.

Step 2: Place the pot on the grill grate or the side burner, depending on your grill’s configuration.

Step 3: Turn the grill to high heat. Keep an eye on the pot, as the water can boil over and spilling. Avoid lifting the lid too often to prevent heat loss and prolong the boiling time.

Step 4: Wait for the water to boil.

Smart Tips

Boiling water on a grill can be a useful skill to have, especially if you’re outdoors and don’t have access to a stove or other cooking equipment. However, there are some important tips to keep in mind to ensure your safety and the quality of the boiled water.

  • Ensure you have enough fuel, whether it be charcoal or gas. If you run out of fuel, the water may not boil completely, or it may take much longer than anticipated.
  • It’s best to place the bottom of the pot or kettle under a fire or embers to maximize the heat transfer. The higher the temperature, the faster it boils.
  • Be sure that the pot or kettle can withstand the heat, especially the plastic or wooden parts on the handles. Turn the handle outward to prevent burning in a high-temperature area.
  • Never leave the grill unattended. Boiling water can take a considerable amount of time, so it’s easy to get distracted and forget about it. Always keep an eye on the pot to prevent the water from boiling over, which can cause a dangerous situation.
  • Don’t grill indoors; it can be hazardous due to releasing harmful gases and the fire risk from hot grills.

How Long Does It Take for Water to Boil?

Gas and charcoal grills typically take around 8-10 minutes or more to boil water, but several factors can affect the boiling time. Knowing these factors can help you estimate the time needed to boil water and adjust accordingly.

1. Temperature

Temperature is one of the most critical factors that can affect boiling time. Water boils at 212 degrees Fahrenheit or 100 degrees Celsius at sea level, but the boiling point changes depending on the altitude or the surrounding environmental pressure. At 1,905 meters or 6,250 feet of altitude, water boils at 93.4 degrees Celsius or 200.1 degrees Fahrenheit.

For example, in Denver, located at a high elevation, water boils at about 202 degrees Fahrenheit or 94 degrees. This is lower than the boiling point of water in Los Angeles, which is close to sea level.

2. Heat Source

The temperature can also be affected by the heat source. Charcoal and gas grills can produce different temperatures, affecting boiling time.

Charcoal grills tend to produce higher temperatures, speeding up boiling time. On the other hand, gas grills can produce lower temperatures, which can slow down boiling time.

Gas or charcoal grills take longer than a stovetop or electric kettle because grills are not designed for boiling water.

Below is a table showing estimated boiling times for a cup of water using different types of equipment:

EquipmentBoiling Time for 1 Cup of Water
Electric Stove2 minutes
Microwave (700W)3 minutes
Microwave (1000W)2 minutes
Electric Kettle2 minutes
Gas Grill10 minutes
Charcoal Grill8 minutes

3. Amount of Water

The amount of water you’re boiling also affects the boiling time. The more water you have, the longer it will take to bring it to a boil. If you’re boiling a large amount of water, it may take significantly longer than just a cup or two.

Following is the calculated time to boil a given amount of water.

Amount of WaterEstimated Boiling Time (minutes)
1 cup (250ml)1-2 minutes
2 cups (500ml)3-4 minutes
3 cups (750ml)5-6 minutes
4 cups (1liter)7-8 minutes

* Please note that these are estimated times and may vary depending on the heat source, container material, altitude, and other factors.

4. Container Material

The container material used for boiling water plays a role in the boiling time. Materials have different levels of heat conductivity, and some heat up faster than others. For instance, stainless steel and aluminum containers are usually faster than glass containers since they conduct heat more efficiently.

Nevertheless, glass containers have the edge over other materials, as they can withstand higher temperatures. On the other hand, it is not advisable to use ceramic and plastic containers for boiling water because they may not tolerate high temperatures.

5. Container Shape    

The shape of the container also plays a role in the boiling time. A wider and flatter container will boil water faster because it has a larger surface area for heat to transfer. A tall and narrow container, on the other hand, may take longer to bring water to a boil.


Boiling water on a grill can be a practical option when other means of heating water are unavailable.

Ensure the grill is appropriately set up, and the pot or kettle can withstand the heat. Besides, understanding the factors that can affect boiling time, such as the amount of water, container material, and heat source, can help estimate how long it will take.

Overall, with the right precautions and considerations, using a grill to boil water can be a safe and effective way in certain situations.


Why Won’t My Water Boil?
