The electric water heater produces hot water and makes it available directly in pipes. Once installed, it is an independent appliance that does not need any other fuel, such as boilers or gas water heaters. Therefore, it does not need revisions or particular maintenance.
The electric water heater or electric boiler, generally installed in the bathroom for convenience in water supply connections, can be closer to the taps and avoid heat dispersion in pipes. On the other hand, smaller models can be easily installed even in the kitchen.
Larger models must consider the wall’s solidity where it will be hung and use special fastening systems. In the same way, check that the electrical system is fully functional and safe. Once installed, the electric water heater can last up to 10 years without special intervention.

How to choose an electric water heater: Types and Characteristics
When buying an electric water heater, there are some important features to consider. The first is consumption. A couple consumes about 60 liters of water a day. Of course, it is only an estimate, and to choose the most efficient water heater, we consider how much water we consume based on the number of inhabitants of a house.
Suppose we prefer the bathroom and shower (the bathroom consumes up to triple the shower). In that case, if we use hot water even to wash the dishes one or more times a day if we are away from home all day, or at home, there is always someone and other personal habits that can affect the consumption of hot water.
Another important distinction is an electric water heater: accumulation or instantaneous. Let’s see the most important technical features below to evaluate which one best fits our needs.
Accumulated water heater
It is the most common, equipped with a tank filled with water and then heated. Depending on the size and capacity of the tank, we will have different performances.
Instant water heater
Low consumption and higher yield are guaranteed with an instant electric water heater. This water heater does not have a tank and can promote high-energy savings. Moreover, it takes up less space than storage water heaters.
Tank capacity
The smaller water heaters have a capacity of between 10 and 30 liters. The advantage is that the water has a much faster heating cycle but ends earlier. They are suitable for one or two people based on how much water is used or support for other water heating systems. They are needed in tiny bathrooms where it would be impossible to place another water heater.
In addition to the bathroom, placing it above the kitchen sink to wash dishes can be beneficial. A water heater with a capacity between 50 and 80 liters is required for a family of two or more. The water will be heated longer, but some are equipped with a double tank. This way, it can heat the water separately for a higher yield.
Timer
The timer is useful for programming switching on and off in larger water heaters. If there is always someone in the house who could use water to shower or wash dishes, it is good to leave the water heater daily. If most of the time the house is empty.
It is beneficial for a timer to activate the water heater a few hours before its intended use, for example, in the evening on returning from work or early in the morning. This way, you do not waste energy but have hot water available at the right time, depending on the family’s habits.
Thermostat
The thermostat serves to regulate the desired water temperature. For an intelligent use of the electric water heater, it would be useful to lower the temperature in summer when we do not need boiling water. Water at 40 degrees is enough for a pleasant shower in the summer months.
Energetic class
Like any other household appliance, the energy class indicates the water heater’s energy-saving capacity. For example, an electric water heater class A mounts high-efficiency internal components and will offer greater savings than one with energy class C.
This parameter often increases the price of a water heater. In any case, the energy class must not be the only parameter. For example, an electric water heater class AAA of 30 L capacity can result in an electric consumption greater than an 80L class B if the first will be induced to heat the tank more times on the same day to meet the needs of a large family.
Orientation
Excluding smaller, very easy-to-install boilers, a 50-liter water heater has a considerable footprint. Depending on the room’s space, we can choose a water heater that mounts vertically or horizontally. Some models allow both options, which is useful if we move to another house one day.
The Best Electric Water Heater quality-price more efficient
Based on the technical characteristics listed, considering a family of 4-6 people, the idea is to buy a model of an electric water heater of 80 liters class A or an electric water heater of 50 liters class A.
