Why Use a Hot Water Bottle?

Why Use a Hot Water Bottle?
If you are looking to save a bit of cash on heating your home this winter, purchasing a hot water bottle may be a thrifty solution. Fill one up and pop it under the covers when you go to bed to keep cosy on chilly nights.

Hot water bottles do more than just keep us warm when the weather gets cold. If you often find it difficult to drift off, it could be down to cold feet. One Swiss study discovered that when our feet are cold, we generally find it harder to fall asleep. Using a hot water bottle stimulates the blood circulation right down to our toes aiding relaxation for a restful night’s sleep.


For those suffering from stiff joints or muscle pain, before you reach for the painkillers, try a hot water bottle instead. Heat therapy is commonly used in rehabilitation to help patients recover from deep tissue injury. This is because heat activates receptors under our skin which block the chemical signals that cause pain to be recognised by the brain.

How to Choose a Hot Water Bottle in the UK ― Buying Guide

In the 16th century, bed warmers containing hot coals were used to warm up the sheets on chilly nights. These days, we have plenty more options than our ancestors. Before making your decision, take a look at our buying guide for tips to ensure you pick the right one!
1

Consider Whether You want a Traditional Hot Water Bottle or Microwaveable Heat Pack

Most of us are familiar with the type of hot water bottle you fill up using hot water from the kettle. But did you know there are varieties that can be heated using your microwave or oven? When comparing hot water bottles, think about what each type has to offer.

Traditional Hot Water Bottles Stay Warmer for Longer

Traditional Hot Water Bottles Stay Warmer for Longer
Hot water bottles come in a myriad of shapes and sizes. A traditional hot water bottle is a re-sealable vessel, usually made from rubber or thermoplastic, into which hot water is poured for the purpose of generating heat. The insulating properties of the hot water bottle mean that heat can’t escape.

Warmth is instead released gradually via convection to the surrounding area, the same way radiators heat our homes. A good quality, traditional hot water bottle can stay warm for up to 10 hours! Making them a great choice if you want long-lasting, sustained heat.

Microwaveable Heat Packs Can Be a Safer Alternative to Traditional Hot Water Bottles

Microwaveable Heat Packs Can Be a Safer Alternative to Traditional Hot Water Bottles

Microwaveable heat packs can be a safer alternative for those concerned about the potential dangers of using hot water. Microwaveable heat packs do not require hot water to generate heat, instead they are filled with a material that retains heat such as wheat or silica gel.

No hot water means you don’t have to worry about accidental burns or scalding, making them a suitable option for those who may have trouble pouring hot water from a heavy kettle or replacing screw caps and stoppers. Simply place in the microwave or oven to warm them up in a matter of seconds to a couple of minutes.


Some microwaveable heat packs are scented and release a gentle aroma when warm. Unfortunately, they tend to only retain heat for a short period of time, usually 20 minutes to 2 hours making them less suitable than a traditional hot water bottle for overnight use.

Pick the Best Material for Heat Retention and Durability

Hot water bottles are commonly made from rubber or PVC, although newer bottles are now sometimes made from silicone. Each material has benefits when it comes to durability and heat retention. Read on to find out more about the properties of each type!

Rubber Hot Water Bottles Are Flexible and Durable

Rubber Hot Water Bottles Are Flexible and Durable
Rubber hot water bottles have been used in Britain since the 1870s! For decades, natural rubber has been a preferred material for hot water bottle manufacturers due to its ability to warm up quickly and retain heat for long periods of time.

Rubber tends to be more durable than non-rubber alternatives and is flexible enough to mould closely to the body when in use. Rubber does, however, have a strong smell that some may find unpleasant.

PVC Retains Heat Better and Comes in More Colour Variations

PVC Retains Heat Better and Comes in More Colour Variations
Types of PVC known as thermoplastics are used as an alternative to rubber for their superior heat retaining properties. A great option if you aren’t a fan of the smell of rubber, PVC comes in a wide range of fun colours. You can even buy transparent bottles to easily check the water level when filling.

Although less prone to degradation than rubber, PVC hot water bottles generally aren’t as flexible, resulting in eventual splitting or cracking over time.

Silicone is Safe For Use in the Microwave

Recently, silicone hot water bottles have become increasingly popular online. Silicone is more flexible than rubber or PVC allowing for a wider variety of applications without compromising the integrity of the bottle.


Silicone hot water bottles are odourless and can be used hot or cold. Safe for use in the microwave, you can quickly and easily reheat a bottle once it’s gone cold. This also makes them a safer option for those who experience difficulty lifting and pouring from a kettle.

Choose The Right Size Hot Water Bottle for Your Needs

Hot water bottles are not one size fits all. Whether you pick a large or small hot water bottle depends on your personal requirements and the way in which you plan to use it.

Large Hot Water Bottles Warm a Greater Surface Area

Large Hot Water Bottles Warm a Greater Surface Area
Large hot water bottles are those with a capacity of 2 litres or more. The bigger the bottle, the more water it can store and the greater surface area can be warmed at one time. Opt for a large hot water bottle for warming your bed or if you wish to apply heat to an area such as the back or torso.

Long, snake-like hot water bottles may look funny, but they are the perfect choice for snuggling up with on the sofa. Their shape allows them to warm several parts of the body at once when wrapped around or laid lengthways.


Due to their greater capacity, large hot water bottles are also heavier. Usually weighing around 2-3 kg on average when filled, they may not be the best option for individuals with reduced strength.

Small Hot Water Bottles Are Lighter and Easier to Carry

Small Hot Water Bottles Are Lighter and Easier to Carry
If you are wanting something more transportable, look for small hot water bottles with a capacity under 1 litre. Small hot water bottles are lightweight and easy to carry so you can fill them up to take with you on a cold day out.

Having a small hot water bottle is convenient when you need to target pain in a specific area and can be useful for soothing headaches. You can even find mini hot water bottles with a capacity of 500 ml or less that are idea for warming your hands.

Buy a Hot Water Bottle With a Cover for Safe Use

Buy a Hot Water Bottle With a Cover for Safe Use
You should avoid placing a hot water bottle in direct contact with the skin. Even when they are not hot enough to cause a burn directly, prolonged exposure can cause hot water bottle rash. This is a skin condition caused by thermal radiation that ranges from a mild itchiness to painful burning sensations and hyper-pigmentation.

Most hot water bottles available to buy online come with a fabric cover. Hot water bottle covers can usually be removed and hand or machine washed depending on the fabric. These not only protect your skin, but come in a wide range of textures, colours and designs to suit every taste.

A Microwaveable Heat Pad for Treating Cramps

Leschi’s Bao the panda warming pillow is designed to ease pain caused by stomach or menstrual cramps, without the need for medication. The round pad can be heated in either the microwave or oven and administers a gentle heat to the lower abdomen to relax muscles.

The pad stays warm for a treatment time of approximately 45 minutes, which can be beneficial for avoiding hot water bottle rash from prolonged exposure. However, the wheat kernels used in this product are unscented and give off a natural aroma, which some may find unpleasant.

Always Fill Your Hot Water Bottle Safely

Always Fill Your Hot Water Bottle Safely
Holding your bottle by the neck in an upright position, fill up to two thirds capacity or less. Pour water gradually to prevent hot water splashing back. If you have removed your bottle from it’s cover, we advise you to wrap the bottle in a tea towel while filling.

Gently and slowly squeeze out any remaining air in the bottle, replace the stopper and return to the bag. Always use your hot water bottle responsibly, do not sit on it or use it as a cushion and never place the bottle directly onto bare skin.
