12 Best Hot Water Bottles | Reviews & Tips

Looking for a hot water bottle? Whether you just need a little extra warmth in your bed at night or are looking for a way to ease aches and pains, hot water bottles are something that should be in every household!

Hot water bottles are basically the same thing as an electric heating pad and oftentimes used for the same thing. One big perk of a them is it’s portable and doesn’t require electricity for you to use it. This makes it a great option if you’re on the go!

If you’re new to hot water bottles let’s start with the basics. What is it and what is the point of it?

What is a hot water bottle and what is the point of it?

A hot water bottle is simply a rubber or thermoplastic bottle with a secure stopper to keep the hot water in.

People use hot water bottles for a variety of uses! They’re used to keep warm (especially in winter!), ease aches and pains from things such as menstrual cramps or back pain or even helping with anxiety.

Things to look for when buying a hot water bottle

1. Type of material

You’ll want to purchase one with a durable material. Most use either thermoplastic or classic rubber.

Rubber is traditional way of making hot water bottles. It’s a thicker material which makes it very durable but it can take longer for heat to be emitted through the rubber. Rubber is also opaque so you won’t be able to clearly see how much water is inside as you fill it.

Thermoplastic can hold heat longer than traditional water and it’s oftentimes translucent making it very easy to see how much water is in your hot water bottle preventing spills (which is very important when using very hot water!). It’s also usually recyclable. There can be some different types of thermoplastic so be sure to check out reviews when you go to purchase a hot water bottle made out of this type of material

Sometimes the mouth of the bottle can use metal. One thing to be aware of this can sometimes rust.

Also look for seams. Ideally you want a hot water bottle without a seam as this can cause unnecessary leaks.

2. Type of mouth

Be sure to look at the type of mouth of your hot water bottle. How wide is it? If it’s too narrow you could have trouble filling it up easily.

3. Is there a cover?

One thing that is a smart thing to get is a cover, especially if you’ll be using these with a child. A cover can help prevent touching a too hot water bottle. If it doesn’t come with a cover you’ll need to find something to use to cover it.

4. How much water it holds

What will you be using it and who will be using it? A typical hot water will hold either 1 or 2 liters of water. Larger hot water bottles are convenient but they can also be much heavier and require more hot water to be heated up.

Smaller hot water bottles are great for small kids or smaller areas of pain. Do a quick look to see how much water is required.

5. Is it microwaveable?

Yes, some hot water bottles are actually microwavable! This could be a good option for you if you need something to heat up quickly. You also don’t have the extra work of dealing with boiling water and the potential for burning yourself.
