When it comes to selecting an electric water heater for your installation, it is essential to conduct a thorough assessment to ensure that you are investing in the most suitable option for your needs. Here is a detailed guide that will help you make an informed decision about which is the best electric water heater for your project or home, considering various key aspects and the best brands available on the market.
Key aspects when choosing the best electric water heater
Capacity of the electric water heater
The capacity of the electric water heater is a critical factor that will determine the amount of hot water available in your installation. It is important to assess the needs of the users in the home or establishment and the daily hot water consumption to select the appropriate capacity. Common options include:
- Electric water heater 100 liters: Recommended for larger families or those with high hot water consumption.
- Electric water heater 150 liters: Designed for homes with a high demand for hot water, such as residences with multiple bathrooms.
- Electric water heater 200/300 liters: Ideal for medium-sized businesses or those with a moderate demand for hot water, or for large organizations or industries that require a continuous supply of hot water for industrial processes, laundries, or other commercial applications.
Energy efficiency
The energy efficiency of an electric water heater is essential to reduce energy consumption and, consequently, the associated costs. Look for models with a high energy rating, preferably A or higher, which indicates lower electricity consumption during operation. This will not only help you save money in the long run but will also reduce your environmental impact.
Brand and reputation
The manufacturer's reputation and brand quality are aspects that should not be overlooked when choosing an electric water heater. Opt for recognized and established brands in the market, which have a long history and a solid reputation for quality, reliability, and customer service. At GroupSumi, we have some of the best brands of electric water heaters such as Thermor, Ferroli, Junkers, and Baxi.
Value for money
It is important to find a balance between quality and price when selecting an electric water heater. The most expensive model is not necessarily the best, nor does the cheapest one offer the best value for money. Make a detailed comparison of the features, performance, and price of different models to determine which offers the best combination of quality and price for your needs.
Additional functions
Modern electric water heaters often come with a variety of additional functions that can enhance their performance and ease of use. Some features to consider include:
- Digital temperature control.
- Scheduled programming to optimize energy consumption.
- Energy-saving modes.
- Protection against corrosion and limescale.
Type of installation
The installation of an electric water heater can be done in both horizontal and vertical positions, and the choice will depend on several factors, including the available space, the plumbing system configuration, and the user's preferences. Below are some considerations for each type of installation:
Horizontal installation
- Available space: Horizontal installation may be more suitable when vertical space is limited. Electric water heaters installed horizontally typically require less clearance height compared to those installed vertically.
- Access: Horizontal installation can facilitate access for maintenance and repair, as the components are often more accessible when located along the wall.
- Aesthetics: Depending on the environment, horizontal installation can provide a more discreet and less intrusive appearance compared to vertical installation.
Vertical installation
- Space saving: In some situations, vertical installation may be more convenient for saving floor space, especially in tight spaces like closets or storage rooms.
- Compatibility with plumbing: In certain cases, the configuration of the existing plumbing may favor vertical installation, making it easier to connect the hot and cold water pipes.
- Stability: Depending on the design of the electric water heater and the installation, the vertical position may provide greater stability and less risk of tipping compared to horizontal installation.
In summary, both horizontal and vertical installations can be suitable depending on the specific circumstances of each situation. Before making a decision, it is advisable to evaluate the available space, the plumbing configuration, and other relevant considerations to determine which option is best suited for your needs.
Additionally, it is important to follow the manufacturer's recommendations and local installation regulations to ensure safe and efficient operation of the electric water heater.

Frequently Asked Questions about Electric Water Heaters
What is better, electric water heater or gas?
The choice between an electric water heater and a gas one depends on several factors, including the availability of gas supply, the available space, energy consumption, and individual preferences.
Electric water heaters are usually easier to install and maintain, but they can be more expensive to operate, especially in areas where electricity is costly. On the other hand, gas water heaters tend to have a lower operating cost, but they require more complex installation and may not be suitable for all environments. The choice between the two types of water heaters will depend on your specific needs and the conditions of your home or business.
Is it better to turn off or leave the electric water heater on?
There is no single answer to this question, as it depends on consumption habits and personal preferences. Turning off the electric water heater when hot water is not needed can help save energy and reduce operating costs. However, keeping the heater constantly on can provide an immediate supply of hot water and avoid waiting times to heat the water. If you choose to leave the heater on, make sure to set the temperature to a level that is safe and efficient for daily use.
If you plan not to use the electric water heater for an extended period, such as in vacations or prolonged absences, it is advisable to turn it off to save energy and reduce the risk of safety issues. Before turning it off, make sure to empty the heater and shut off the water supply to prevent possible leaks or damage from freezing. When you return, turn on the heater and allow the water to heat up completely before use.
Remember that it is always advisable to consult the manufacturer's instructions and follow best practices to ensure the safe and efficient operation of your electric water heater.
Which electric water heater consumes the least electricity?
The electricity consumption of an electric water heater can vary significantly depending on several factors, including its capacity, energy efficiency, level of insulation, frequency of use, and temperature setting. However, in general, electric water heaters with a high energy efficiency rating (for example, an energy rating of A or higher) tend to consume less electricity compared to those with lower ratings.
What is the appropriate temperature for an electric water heater?
The appropriate temperature for an electric water heater can vary depending on individual preferences, the intended use of hot water, and safety considerations. However, a temperature of between 45°C and 60°C is generally recommended for the water stored in an electric water heater.
