7 Ways To Keep Water From Freezing

Ways to keep water From freezing during winter camping

1) Use an Insulated Bottle or Bottle Jacket

Using an insulated bottle or bottle jacket is a highly effective way to keep water from freezing in winter camping. 

  • Insulated bottles are typically made of stainless steel and feature double-walled vacuum insulation that helps maintain the temperature of your beverages in cold weather conditions.
  • Bottle jackets, on the other hand, are insulating sleeves that you can slide onto your regular water bottle to provide an extra layer of insulation. 

How to choose the right insulated bottle?

When choosing an insulated bottle, opt for stainless steel options with double-walled vacuum insulation for maximum heat retention. 

Some popular brands like Hydro Flask, Yeti, and Klean Kanteen offer a wide range of insulated bottles suitable for winter camping. 

Pros and cons

  • Pros:
    • Reliable insulation.
    • Durability.
    • Widespread availability.
    • Reusable and can be used for both hot and cold beverages.
  • Cons:
    • Limited capacity compared to other options,
    • May add weight to your gear.

Despite these drawbacks, using an insulated bottle or bottle jacket is a practical choice for keeping water from freezing. 

2) Heat your water before you go camping

Before setting out on your winter camping trip, heat water to a near-boiling temperature and pour it into a thermos or insulated bottle. 

The high temperature of the water will delay the freezing process, allowing you to have access to liquid water for a longer period. 

When you’re ready to drink, simply pour the hot water into a cup or mix it with cold water to achieve your desired temperature.

  • Pros 
    • The immediate access to liquid water, especially in cold temperatures. It eliminates the need to rely solely on insulation methods during your trip.
    • The convenience of having hot water readily available for warm drinks or meals. For example, you can enjoy a soothing cup of hot tea or prepare a dehydrated meal with hot water right at your campsite.
  • Cons
    • Heating water before camping requires a heat source, such as a stove or kettle, to boil the water. This means you need to plan and allocate time for this preparation step.
    • The heated water will gradually cool down over time, so it’s important to drink it or use it for cooking before it reaches freezing temperatures. 
    • Regularly refilling the thermos with hot water will be necessary to maintain its warmth throughout the day.

3) Buy an Insulated Bladder

These hydration systems consist of a flexible reservoir and a drinking tube. Insulated bladders are designed to keep the water inside at a consistent temperature, preventing it from freezing. 

How to choose the right Insulated bladders ?

When choosing an insulated bladder, there are a few tips to keep in mind. 

  1. Consider the insulation quality and thickness. Look for bladders with high-quality insulation materials that provide efficient temperature retention. 
  2. Evaluate the capacity and size of the bladder. Depending on your camping needs, select a bladder with an appropriate capacity that can accommodate enough water for your trip. 
  3. Consider the durability and ease of use. Look for bladders with sturdy construction and user-friendly features such as a reliable sealing mechanism and an easy-to-use drinking tube. 
  4. Pay attention to additional features like insulation sleeves or covers that provide extra insulation and protection against freezing temperatures.

Check out these 5 Best Hydration Bladders.

  • Pros
    • Large capacity.
    • Convenient for long hikes.
  • Cons
    • May freeze if not properly insulated.
    • Requires cleaning and maintenance.

4) Use a Soft Flask

Soft flasks are collapsible water bottles that are typically made of lightweight and flexible materials. 

They are convenient for winter camping because you can squeeze out excess air, reducing the space available for freezing water. 

Soft flasks are also easier to carry in a jacket pocket, keeping them closer to your body heat and delaying the freezing process.

  • Pros
    • Lightweight.
    • Collapsible.
    • Easy to carry.
  • Cons
    • Limited capacity.
    • May require frequent refilling.

5) Sleep with your water bottles in your sleeping bag

An unconventional but effective method for preventing water from freezing is to sleep with it. 

Before going to bed, make sure your water bottle or bladder is securely sealed and place it inside your sleeping bag. 

Your body heat will act as a natural insulator, keeping the water from freezing overnight. This method is especially useful if you anticipate extremely cold temperatures.

  • Pros
    • Utilizes body heat.
    • Doesn’t require additional gear.
  • Cons
    • Limited capacity.
    • May not be suitable for extremely cold temperatures.

6) Bury your water bottles in snow

If you’re camping in a snowy environment, consider burying your water containers in the snow. Snow acts as an insulator and can help maintain a relatively stable temperature for your water. 

Dig a hole deep enough to bury the containers or bottles, ensuring they are well-covered with snow. 

Remember to put the bottle upside down with the threads/cap on the bottom. Also, mark the location to avoid losing track of your water source.

  • Pros
    • Utilizes natural insulation.
    • Keeps water relatively cool.
  • Cons
    • May be challenging to locate buried containers.
    • Requires snow.

Bonus trick: Just before going to sleep, heat up some water, bury it in the snow, and when you wake up in the morning, it will remain in its liquid state. This method is effective only with a heat-resistant bottle, such as a Nalgene. 

7) Use a Chemical Heat Pack

Chemical heat packs, commonly used for hand and body warmers, can also be utilized to prevent water from freezing. These packs contain chemicals that generate heat when activated. 

Place a heat pack around your water bottle or bladder to provide additional warmth and delay the freezing process. 

Keep in mind that heat packs have a limited duration, so bring extra packs if you plan for an extended camping trip.

  • Pros
    • Provides additional heat.
    • Easily accessible.
  • Cons
    • Limited duration.
    • Requires additional packs.

Choosing the Best Method for Keeping Water from Freezing While Winter Camping

When deciding which method to use, consider your personal preferences and the specific camping conditions. 

Evaluate the effectiveness and convenience of each method, keeping in mind factors such as insulation, portability, and ease of implementation. 

It’s advisable to plan ahead and test different methods before your camping trip to determine which one works best for you.
