Buying criteria: factors that allow you to compare and rate different models of electric water heaters

When you have a wide variety of models and brands of electric water heater in front of you, it is difficult to know which is the product that will satisfy you for days to come. To clear your mind in that situation we have created this section, where we will show you factors to look out for before buying an electric water heater.

One of the first factors that we will show you and that form a crucial part of a good buying criteria are the uses. We will show you what options you have when it comes to using an electric boiler, and we will give you recommendations on how to get one.

Office appliance. An electric water heater can be the ultimate office appliance. It's compact and all you need to do is plug it into the mains to start heating water. If you eat instant soups, drink coffee, tea or other beverages at work, we advise you to buy one, smart or not.

Car thermos. Got to rush out of the house to get home early? Make tea on the go or keep your coffee hot with an electric thermos that can be plugged into your car's cigarette lighter. Whether it's smart or the simple variant, you can make your life simpler with it.

Camping. It's always great to be in touch with nature and nothing beats camping. If you want to be able to have a hot drink or prepare something special, you should have an electric thermos of any kind among your devices.


The second most important aspect when you are about to buy an electric thermos is the capacity it has to contain a substance, that is, the amount of millilitres it can hold. This directly affects its price.

Low. A low capacity electric boiler is one that can give you 200 to 400 ml in its cup. This is a limited amount of drink, but it is perfect for a good coffee. If this is what you want, our advice is to buy a smart thermos, so you can set everything yourself. Small but blessed!

Medium. Medium capacity electric thermoses can hold 400 to 800 ml, a perfect amount for all kinds of drinks and even for preparing a small meal that requires boiling water. Do you need one like this? We recommend both simple and smart thermoses, both will meet your demands.

High. High capacity products in electric water heaters are those that can work with 800 to 1200 ml, in short more than enough for one person and you could even invite one more. In these cases our buying advice is to buy a simple thermos, they are the largest capacity and cheapest.

Type of connector

As our thermos flask is electric, it is important to know how to connect it to a power source in order to have more possibilities in terms of use and transport. The type of connector is another factor in the purchase of our thermos flasks.

Car plug. Cars have a cigarette lighter socket, there are models of electric thermos that have a connector that fits perfectly into this type of socket. This will allow you to take your thermos and your piping hot drink wherever you want to go. Both simple and smart thermoses are good options.

USB. If you don't have a car nearby but you do have your computer or other device, use a USB cable to plug in your thermos. This type of connector is perfect for office use, although it tends to be a little slower than the others. If you want a product with a USB connector, get a smart thermos.

Simple connector. This is the typical connector for electrical plugs or sockets, which you can find everywhere. If you like to have quick results and have multiple places to leave your electric boiler this is the most suitable, both the simple and the smart boiler have this type of connector.

Extra functions

Electric water heaters have different aspects or functions that also need to be taken into account to get the product that gives you the best possible performance. These aspects are the insulation, the appearance of your thermos and its touch panel.

Insulation. The insulation function of the electric water heater is extremely important because if you don't have it when you touch your cup you could burn yourself. This technology consists of using high quality manufacturing materials to maintain a high temperature on the inside and room temperature on the outside. No burns.

Appearance. When buying a product it is always nice to choose the one we like, not only for its functions or capabilities, but also for its appearance. The appearance and design of the electric water heater is another extra aspect that will help you decide which one to choose and which one not to choose, the great thing is that it all depends on your taste

Touch Panel. This is an extra feature that only smart electric water heaters have. It's a great feature to be able to set the temperature you want in your cup, especially if you prepare a tea that needs a particular point.
