10 Best Electric Hot Water Heater 2020 – Reviews

Choosing the best electric hot water heater is not a task that should be taken lightly.

After all, it isn't something you buy just because you want it. It's a product that falls under the "needs" category. Just imagine having to take a bath without hot water during the cold months.

There are many types of water heaters. If you want to know why you should opt for the best electric hot water heater and which one to get precisely, then make yourself a cup of coffee and discover all you can about this necessity.

Electric Hot Water Heater: What It Is and Why Should You Buy It

An electric hot water heater is pretty straightforward. As the name implies, it's a device that heats up water for you to use.

Unlike other heaters that use natural gas or solar power, this one uses electricity to warm up heating elements to deliver hot water to you.

The advantages of using the best electric hot water heater

Electric water heaters are more affordable than gas-powered ones and other similar types of heaters using different fuels.

You also won't need additional piping and ventilation systems when you use electric heaters. As a result, you spend less on installation.



The downsides of using an electric water heater

Even the best electric hot water heater has limitations. First, it takes longer for an electric heater to heat up water than a gas-powered one.

You also cannot use your electric heater if the power goes out or during a blackout.

However, the biggest downside to having an electric water heater is that you will be spending more in the long run. Electricity is much more expensive than natural gas in most areas.

Types of Electric Hot Water Heaters You Can Buy

Regardless of the fuel used, there are four main types of water heaters.

Tank-type heaters

Tank-type water heaters have a storage tank that can hold hot water until you need it.

These tanks can hold anywhere from 20 gallons to 80 gallons of water, depending on the size. Getting this type of heater is a good option if you need hot water throughout the day.

However, if there are many people in the house and many appliances using hot water at the same time, a tank-type heater is not a good idea.

Also, to ensure that hot water is always available, these heaters will use up electricity or gas to maintain higher temperatures.

Tank-less water heaters

If you don't have enough space to accommodate a big tank, you can still get hot water for the whole house using tank-less water heaters. These heaters are mounted on walls.

With these tankless heaters, you can get hot water on demand. Because you're not storing water, the appliance will only use gas or electricity when you open the hot-water tap.

It works the same way as a tank-type heater, but it sends hot water straight to the faucet or appliance that needs it, instead of into the storage tank.

Tank-less water heaters also last longer than tank-type ones. However, it does cost a lot more to go tank-less.

Hybrid water heater

If you don't like the idea of having to use electricity just to keep an entire tank full of water hot, you can choose a hybrid water heater. It uses an electric heat pump that consumes around 60 percent less electricity than traditional tank-types.

When you need hot water, this heater will capture heat from the room and then use that to heat cold water.

It may save you from using too much electricity, but you have to pay more for this type of heater. Sometimes, it costs twice the price you pay for a traditional tank-type.


These water heaters are tank-less and provide hot water to a specific appliance or location. You can often find point-of-use heaters in your shower or sink.

These water heaters heat water instantaneously and on-demand so you don't have to wait. It also doesn't waste electricity.

They are small, usually measuring around a foot in width and height. They can easily fit inside cabinets, closets, or near your shower.
