Here is a list of the four best residential water heaters you can get on the market today. Let’s get started!

ECOTOUCH 9KW Electric Tankless Water Heater

ECOTOUCH 9KW Electric Tankless Water Heater


The best thing about electric water heaters is that they are the most eco-friendly option. They have the highest energy factor, which means they are very energy efficient. The ECOTOUCH heater is no different.

It has an energy efficiency rate of 99.8, which helps save a lot of energy, resulting in you spending significantly less on water heating.

You get hot water instantly when you turn on the faucet without having to wait. The heater does not need time to preheat, and the temperature of the hot water produced is consistent without dramatic fluctuations like in many other heaters. This is the kind of reliability you want from a heater.

You can also get an unlimited amount of hot water at a flow rate of 1.5 gallons per minute.

Another excellent feature with the ECOTOUCH heater is the smart self-modulation technology that adjusts temperatures of the water according to the flow rate. When the flow rate decreases, you don’t have to endure overly hot water while you are already in the shower.

The heater does this by reducing the amount of energy supplied to mirror the amount of water going through the pipes. This saves even more energy!

Another thing you will love about this heater is the digital display and the smart touch control panel that allows you precise control over the heater. For your safety, the water and electricity lines are completely separated, to prevent scale build-up and avoid leakages as well.

Considerations for the Best Residential Water Heaters

When you are looking for a residential water heater, you know it’s something you are going to get stuck with for a long time. For this period, your water heating unit is going to be at the center of the household’s hot water chores and activities, such as doing the dishes, showering, and boiling pasta, among other things.

This is why you should take the task of choosing your next residential heater very seriously, and to do so successfully, you need to know what you should be looking for in the search. Here are the most important factors to consider as you look for a new water heater.

Warranty information

A heater’s warranty information is one of the most important considerations to keep in mind. A great warranty helps you to easily access help if you encounter trouble with the water heater, or if it fails to function in some way.

A great warranty also lets you know that the manufacturer believes in their product and are therefore willing to stand by it.

The Size

Although traditional tank water heaters that take lots of storage space have significantly declined in popularity, you still need to check a heater’s dimensions to ensure it can fit in a space you plan to mount or install it.

Running cost

The running cost of a heater is the cost you will have to incur in terms of heating energy. A gas water heater, for instance, is more economical to run when you have a large family in comparison to electric water heaters. This should tell you what kind of energy source you need your water heater to run on.

The Volume of Water Required

The volume of hot water you need to run your household is an important guiding factor when it comes to deciding which water heater to choose. The amount of hot water you can get from a heater is determined by the heater’s flow rate.

It’s good to keep in mind that the volume of water you get from a heater may be lower depending on the groundwater temperature. For this reason, you should always give yourself 1 to 2 gallons per minute allowance. What I mean is, if you need a volume of 3 gallons per minute, be sure to get a heater rated 4 or 5 gallons per minute.

The Type of Energy 

Some heaters are more expensive to run than others, depending on the type of energy they use. This makes some heaters better for larger amounts of hot water than others.

Gas water heaters are better when you need large amounts of water, compared to the cost of electric water heaters. if you have a big family, you are better served by a gas water heater.


You must vent your heater well to avoid poisonous fumes from accumulating in your house. Electric water heaters don’t need venting. Gas water heaters, on the other hand, need to be properly ventilated.

While some water heaters come with a venting kit, others do not. You need to pay attention to the kind of venting you need for your heater, especially if the venting kit is not included in the purchase.


Water heaters are expensive, and when you get one, you want to make sure it lasts for a long time. If this is your goal, then you need to pay attention to the construction of the heater and make sure it’s made of quality materials.

This way, you will know that you can rely on the heater for a long time without worrying about breakdowns.
