Best Hot Water Bottle Buying Guide

Hot Water Bottle Size

Hot water bottles are no longer just manufactured in a one size fits all model so now you can choose from a range of sizes that fit your needs.

Large Hot Water Bottles

As the name suggests, these hot water bottles are larger so they can hold a larger volume of water. Larger hot water bottles aren't as effective at retaining heat because of their larger surface area, but it also means that you can treat a larger area of your body which means you can reduce your pain quickly.

A larger hot water bottle does make it heavier, which can be an issue for the elderly or if you suffer from joint issues.

Small Hot Water Bottles

In comparison to large hot water bottles, these are smaller in size, which makes them more compact and easier to carry. Their size also makes it quicker to fill, and they are great at retaining heat for long periods, which makes it ideal if you plan to use it while you sleep.

Small hot water bottles are ideal if you have a specific spot that your pain is coming from while also being small enough to take on your travels when you leave your home.

Long Shaped Hot Water Bottles

As with any product category, hot water bottles now come new shapes and sizes with some having a long sleek design while still having all the benefits of a traditional hot water bottle. This stylish, long shaped design means that it has a greater number of application uses, so, for example, you could wrap it around your bicep if you have an arm injury.

This also means that it will stay in place more securely if you're using it while you sleep. This shape gives you greater versatility so you can have one hot water bottle for all situations.

Small hot water bottles are ideal for smaller children or if you have a small area of pain, whereas the average hot water bottle has a capacity of around 2 litres which is adequate in most circumstances.


You need to consider the material of your chosen hot water bottle because this will determine its overall quality and durability. The main materials are:


Hot water bottles have long been made from a rubber material and can range from naturally manufactured rubber or recycled rubber. Rubber has many great benefits, including being flexible so it can bend to make it feel comfortable.

Rubber also has strong heat retention capabilities so it won't feel too hot and burn your skin when you use it, but will also stay warm for longer periods, so you don't have to keep refilling it.

It's common for the rubber to not be see-through so this makes it difficult to know how full it is when you're filling it with water.


You can also choose a hot water bottle that's made using thermoplastic which similar to rubber, has a high heat retention level so you can fill it once and it'll last many hours. There are also thermoplastic hot water bottles that are transparent, so you don't have to guess the water level when you're filling it up, which is also a greater safety feature.


Although it's unlikely you'll find a hot water bottle that's made completely of Copper, it's normal that some of the components such as the bottleneck will be made of Copper. Copper is very corrosion resistant but is also great at transferring heat energy, and because of their firmness, it means you have something to hold while you refill. Copper is also long-lasting and easy to clean.

Hot Water Bottle Filling

Nowadays the filling for hot water bottles isn't only water. If your children are going to be using it and you're worried about them being around hot water, then you can now get microwaveable bottles that have material built into the fabric. The fabric heats up and can reach the same temperature as a standard hot water bottle.

Due to them not having the threat of bursting or your children, opening them it makes it great for kids to use. Of course, bottles that use hot water can retain heat for longer periods depending on the model, but this is a great alternative.


Hot water bottles come in a range of sizes and materials, which means that the selling price can vary massively. The cost will also be determined by the brand of hot water bottle with more established brands often using higher quality materials which increases the selling price.

We'd always recommend spending more on a higher quality product because this often will get you a longer-lasting product so it'll need replacing less often and will have a lower chance of developing a fault.


You must ensure that you choose a durable and well-made product because you're going to using hot water. Hence, you must be well protected especially if younger aged children will be using it too.

You should try and avoid low-quality materials and choose the highest quality option such as rubber or thermoplastic, that is less likely to split or burst. Durability is closely linked to the brand and cost of the item.

Protective Cover

It's normal for manufacturers to provide a colourful fabric cover with the water bottle, which helps to extend the life of the product.

They're usually made of a comfy material which makes it nicer to cuddle up to and keep warm. These covers will often also be stain-proof and give additional protection for the bottle to reduce the chance of a puncture occurring.

Although it's not 100% necessary, a hot water bottle cover is an excellent addition to your purchase to give added durability and protection. It also allows you to have a unique looking product versus the standard look of a hot water bottle. We'd recommend a fleece material as they are soft and cosy.


Due to you having to handle hot water, you must check whether your chosen hot water bottle meets any British manufacturing standards. This will give you the added peace of mind that you're buying a higher quality product that is less likely to fail on you.

You want to avoid any cheaply made hot water bottles, but safety also comes down to how you use the product and not just the manufacturer's responsibility.

You should never use water that has been boiled to the max but instead stop it just before, so it's still hot but just not boiled otherwise this can be a burn hazard.

You should also never fill the water bottle to the rim and makes sure that at least 25% of the bottle is unfilled before you close it you should gently squeeze out excess air which stops the threat of it bursting.
