How to Choose a Hot Water Bottle – Buying Guide

Picking the right bottle is about finding something that meets your needs in terms of both quality and practicality. So don’t forget to consider how it would fit into your lifestyle.

Choose a Bottle Material That's Durable and Retains Heat

The two main materials that hot water bottles are made from are rubber and thermoplastic, and choosing which one you want is really a matter of preference rather than quality.

Rubber is Long-Lasting and Reliable

Rubber is Long-Lasting and Reliable
Traditionally, hot water bottles are made from rubber as it retains heat well, lasts for years, and can take a bit of a beating. However, rubber is opaque, and you won’t be able to see how filled your bottle is, which might be an issue for those less familiar with hot water bottles.

Rubber is also more malleable and easy to bend, so it can be more comfortable to hold or lie in bed with as it's made to withstand being pushed and pulled around. However, rubber does contain latex, and those with latex allergies should steer clear, even if you use a cover with it.

Thermoplastic Retains Heat Better but Can Be Less Consistent

Thermoplastic Retains Heat Better but Can Be Less Consistent
Thermoplastic is a type of PVC that retains heat extremely well. It can stay warm longer than rubber can and is sometimes transparent for easy filling. Thermoplastic is also usually recyclable.

Hot water bottles made of thermoplastic can be either flexible or solid. The flexible ones behave in a similar way to rubber hot water bottles, as they can be bent and manipulated as you please. However, solid bottles are rigid and do not allow for any movement, so keep this in mind if you opt for a thermoplastic bottle.


Despite the fact that some of the best hot water bottles are made from thermoplastic, you may find some quality discrepancies between bottles depending on the company. That's why it’s important to read reviews before buying.

Pick a Size That Suits Your Target Area

Pick a Size That Suits Your Target Area
Larger capacity water bottles hold more water. Therefore, they have higher heat capacity, and given the smaller ratio of surface area to water, they’ll release heat more slowly than bottles with smaller capacities.

They’re also better for warming larger areas, such as if you’re trying to heat up a bed or even target areas like your abdomen or back. The most common size for hot water bottles is around the two-liter mark, and these are the perfect size for placing on your stomach or your lower back. For heating larger areas such as a bed, you might want to try bottles nearer three liters.

On the other hand, smaller bottles, such as those around one liter, will be lighter when full and are easier to store and take care of. They're also handy for targeting specific areas that might be difficult with a larger bottle, such as your neck or your ankles. 

Find a Bottle with a Cover for More Safety and Comfort

Find a Bottle with a Cover for More Safety and Comfort
Since you’ll be filling your hot water bottle with nearly boiling water, it’s important to also have a cloth cover for it so that you’re not directly touching the bottle and risking burns. Although the cover will prevent the full warmth of the hot water bottle being immediately felt, it won't prevent you from feeling the heat over the hours that you use it.

If this is your first hot water bottle or you’re looking into getting a different size or shape, it would be helpful if it came with a cover. It saves you from having to make another order, plus you know that it’ll fit perfectly. Some covers are pretty generic, but there are a few companies that sell their bottles with a wide variety of adorable covers, too.


Covers are intended to be soft to the touch and comfortable to hold, so you'll find many made from materials such as fleece, faux fur, and various knitted fabrics. These covers can often be washed so you can be certain that your hot water bottle will always be clean and soft!

Extra Tips: For Convenience, Consider a Microwaveable Bottle

Extra Tips: For Convenience, Consider a Microwaveable Bottle
If you don’t want to wait for your water to heat up, look for a hot water bottle that can be microwaved. Microwaveable bottles can be heated up within just a couple minutes, and you don’t have to worry about accidentally burning yourself trying to fill your bottle with hot water.

Just be sure to read and follow all directions carefully so that you don’t damage the bottle. If a microwavable hot water bottle is heated for too long, the material can be become damaged and the insides might leak. You should also ensure that your microwave is large enough for the bottle to freely rotate while it heats as if it can't, it will heat unevenly and risk damage.


Although there is no chance of burning yourself from pouring hot water with this type, you do need to be careful when first handling the bottle after it's been microwaved. They can be very hot to the touch, and if you need to put the inner pocket back inside its cover, you should wait before doing so or you might burn your hands.

How to Safely Fill a Hot Water Bottle

How to Safely Fill a Hot Water Bottle
Considering you’re pouring hot water into a bottle meant to be put on your body, it’s fairly important that you know how to fill it properly and safely. First, visually check that there are no cracks in the bottle or the neck of the bottle. 

Place the bottle inside its case so that you're not directly touching the material of the bottle and hold it over the sink. Make sure you have full control of how much water is being poured, as pouring too fast increases the chance of splashes and burns. We would advise using a kettle with a spout as it’ll give you more control than pouring out of a saucepan.

How to Safely Fill a Hot Water Bottle

You should also ensure that the water you use has been left to cool for a while and isn’t boiling. Boiling water can not only damage the integrity of the bottle, it will also cause painful burns if you spill any. A few degrees can make a huge difference!


Carefully pour the heated water into it until it’s about two-thirds full. Gently and slowly squeeze out the remaining air, being careful that no water escapes, until the water level rises to just below the top. You can then replace the stopper, making sure it's tight, and turn the bottle upside down to check for leaks.
