The 10 best electric water heaters of 2021
Lately, electric water heaters are becoming more and more demanded devices thanks to their wide range of advantages, but we will highlight two. It requires less maintenance and as soon as you turn on the tap the water is already hot.
What is an electric water heater?
Understanding the operation of the thermos 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 is turned off to prevent overheating. Depending on the model, its capacity may vary but the standard is 80 liters.
The 6 things you should keep in mind before buying an electric water heater?
1.- The capacity:
The first decision that you must take into account is the capacity of the electric water heater that will depend on the number of people who live at home.
To standardize, it is calculated 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.
Thus:
- For 1 person, a 25 to 50 liter thermos is enough.
- For 2 people, 50 to 80 liters.
- For 3 people, 80 to 100 liters.
- More than 4 people, between 150 and 200 liters.
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 it will fit you. 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 they adapt very well to the space.
The most common space to install it is in rooms where hot water is used more, 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 full thermos.
4.- Maximum pressure:
The great advantage of electric water heaters compared to 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 that 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 an adjustable temperature, which allow you to choose the water temperature since they have 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 water heater with a shielded resistance, which transmits the 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 avoids the corrosion of lime.
