Hot Water Bottle vs Wheat Bags: Which One is Better?

Hot Water Bottle vs Wheat Bags: Which One is Better?

, by AussiePharmaDirect, 8 min reading time

Hot water bottles have stood the test of time as a classic and reliable heat therapy companion. Just the thought of cuddling up with a hot water bottle on a chilly evening brings a sense of comfort and warmth. The process is simple yet effective – fill the bottle with hot water, seal it tightly, and wrap it in a soft fabric sleeve. This snug bundle of warmth can then be placed on any area of your body in need of tender care.

Wheat bags, on the other hand, offer a more natural and sustainable approach to heat therapy. Filled with wheat grains or other organic materials, these soft fabric bags become a source of gentle warmth after a quick trip to the microwave or oven. The heat-retaining properties of the grains ensure that your wheat bag stays warm for a comforting duration, providing soothing relief wherever you need it most.

Despite their similarity in offering soothing heat therapy, hot water bottles and wheat bags each possess distinct qualities that set them apart from one another which we’re going to explore in this blog.

Let’s compare the features


Hot water bottles

Wheat bags


Typically made of rubber or heat-resistant plastic. The material is durable and can withstand hot water without deforming or leaking. The outer covering is usually a soft fabric or fleece sleeve to insulate the heat and prevent direct contact with the skin.

Made of fabric and filled with natural materials, such as wheat grains, rice, corn, or flaxseed. The fabric cover is usually soft and comfortable to the touch, and the grains inside have excellent heat-retaining properties.

Shapes and sizes

Come in standard shapes, resembling a rectangular or oval pouch with a narrow neck. The sizes may vary, ranging from small (around 0.5L) to large (up to 2L). Some designs may have ribbed patterns on one side, allowing for better heat distribution.

Offer a wide variety of shapes and sizes to cater to different body parts and specific needs. They come in rectangular shapes, long and slender designs for neck and shoulders, eye masks, mittens, booties, lower back wraps, joint wraps, and more.

Heating method

Require filling with hot water from a kettle or tap. They rely on hot water to provide warmth, and heat retention depends on the material and insulation of the bottle.

Heated in a microwave or oven. The grains inside absorb the heat and retain it, offering a sustained and natural warmth that gradually dissipates over time.

Customisation and targeted heat

While hot water bottles offer versatility in terms of sizes, the heat distribution is relatively uniform, making them suitable for larger areas of the body but less precise for targeting specific spots.

Wheat bags excel in targeted heat therapy due to their various shapes and sizes. They can be placed precisely in the desired area, providing localised warmth and comfort.

Aromatherapy and infusions

Do not typically offer aromatherapy benefits unless infused with herbs or essential oils in the fabric cover.

Many wheat bags come infused with calming scents like lavender or chamomile, adding an aromatherapy element to the heat therapy experience.


Common benefits of hot water bottles and wheat bags

Both hot water bottles and wheat bags share common benefits that make them popular choices for heat therapy and relaxation. Regardless of their differences, these two heat therapy solutions offer the following advantages:


  1. Soothing heat therapy: Both hot water bottles and wheat bags provide gentle and consistent warmth, effectively soothing sore muscles, easing joint discomfort, and relieving menstrual cramps.
  2. Reusability: Both can be reheated and used multiple times, making them cost-effective and eco-friendly options for heat therapy. This reusability reduces waste and supports sustainability.
  3. Portable and travel-friendly: Both hot water bottles and heat bags are lightweight and easy to carry, making them convenient for travel or use on the go. They offer a comforting touch of warmth during long journeys or chilly nights away from home.
  4. Customisable heat levels: With hot water bottles, you can adjust the water temperature before filling, while wheat bags can be heated for varying durations to achieve the desired warmth.
  5. Non-invasive and natural: Both heat therapy solutions do not involve any chemicals or medications, making them gentle and suitable for many individuals.

The disadvantages of hot water bottles and wheat bags

While hot water bottles and wheat bags offer numerous benefits for heat therapy, they also come with certain drawbacks.


One of the primary safety concerns with hot water bottles is the risk of overheating the water. If the water is too hot or left in the bottle for an extended period, it can cause burns or scalds when in direct contact with the skin. Similarly with wheat bags, there is a risk of burning if they are overheated or if the heating instructions are not followed correctly. 


Hot water bottles can develop leaks over time, especially if they are not properly maintained or if the rubber or plastic material becomes worn. A leaking hot water bottle can result in hot water spilling onto the skin, causing burns or injuries.

Electric hot water bottles and electrical hazards

Electric hot water bottles come with their set of safety concerns. Charging them for extended periods or using faulty electrical connections can lead to overheating and potential electrical hazards.

Need for a heat source

Both hot water bottles and wheat bags require a heat source for heating. For hot water bottles, this means access to hot water from a kettle or tap. Wheat bags need to be heated in a microwave or oven. This can be inconvenient, especially when a heat source is not readily available.


Filling a hot water bottle with hot water and waiting for it to reach the desired temperature can be time-consuming. 

Need for refilling or reheating

Hot water bottles need to be refilled with hot water after each use, and wheat bags require reheating before each use. This extra step can be inconvenient, particularly for individuals seeking quick and immediate heat therapy.

Which one is better?

When considering the disadvantages between hot water bottles and wheat bags, it becomes evident that wheat bags have a more favourable balance. Both products share certain safety concerns, such as the risk of overheating, but hot water bottles face additional issues like leakage and electric hazards, making them less desirable in this aspect.

Beyond safety and convenience, the materials used in wheat bags make them a more sustainable and eco-friendly option. With their natural fillings like wheat grains, rice, corn, or flaxseed, wheat bags leave a smaller ecological footprint compared to hot water bottles made of rubber or plastic.

Ultimately, as with many decisions in life, the choice between hot water bottles and wheat bags ultimately comes down to your specific needs and preferences.
