The 10 best electric water heaters of 2022

What is an electric water heater?

Understanding how thermoses work is very simple. It is a bucket made of insulating material and inside the water is heated by an electrical resistance, once the temperature is reached, this resistance turns off to avoid overheating. Depending on the model, its capacity may vary, but the standard is 80 litres.

The 6 things you should take into account before buying an electric water heater?

1.- The capacity:

The first decision you must take into account is the capacity of the electric water heater, which will depend on the number of people who live at home.

To standardize, it is estimated that a person consumes around 25 liters per shower / day, we say shower since it is the time when a person uses more hot water.

Therefore:

- For 1 person, a thermos of 25 to 50 liters is enough.

- For 2 people, 50 to 80 litres.

- For 3 people, 80 to 100 liters.

- More than 4 people, between 150 and 200 litres.

2.- Where to locate it:

Depending on its capacity, the electric water heater needs more or less space, our recommendation is that you make sure that it will fit. Keep in mind that to connect the hoses you will need approximately 20 centimeters of additional space.

In Rehabilitaweb you can find both the horizontal thermos and the vertical or cube-shaped thermos, so that they adapt very well to the space.

The most common space to install it is in rooms where hot water is used the most, such as the kitchen or bathroom.

3.- Weight:

The weight will also depend on the capacity. At the time of assembly, it must be installed on masonry walls that are capable of supporting the load, it must never be installed on partitions or plasterboard walls because they will not support the weight of the filled thermos.

4.- Maximum pressure:

The great advantage of electric water heaters over gas heaters is that they work with any type of flow, thus avoiding pressure problems.

5.- Power and heating time:

As for power, the standard models you can find on the market are 1200W.

As for the heating time, there are two types of thermos, those with a fixed temperature, the water is always at the same temperature, and those with adjustable temperature, which allow you to choose the temperature of the water since they have of a thermostat.

6.- Type of resistance:

The type of resistance depends on the hardness of the water where you live. If the water is soft, the best option is an electric thermos with armored resistance, which transmits heat to the water directly. If, on the other hand, the water is hard, the best option is a sheathed ceramic resistance thermos, which is not in direct contact with the water and thus prevents limescale corrosion.
