When you’re looking for an electric water heater for your home, there are several key factors to consider. It’s not just about choosing the cheapest option, but about investing in a model that offers efficiency, durability, and safety. Below, I will explain the characteristics a good electric water heater should have so you can make the most of your purchase and avoid long-term problems.
Opt for an electric water heater with an A++ or A+++ energy rating. High-efficiency models can reduce electricity consumption by up to 30-40% compared to older models. This translates into significant savings on your electricity bill, which is ideal if you’re looking to reduce household costs.
The energy consumption of an electric water heater depends on its efficiency, which is measured using the energy label. Since 2017, manufacturers have been required to include these labels, which classify appliances from A+++ (maximum efficiency) to G (lowest efficiency). Although manufacturers calculate consumption based on a standard usage profile, this data is useful for comparing electric water heaters but does not guarantee an exact estimate of your annual spending. It is recommended to use these labels for comparisons rather than as an accurate estimate of your bill.
2 Ideal Capacity: Suited to Your Needs
The size of the electric water heater is crucial. If you live alone, a 30-50 liter model will be sufficient, while for a family of 3-4 people, an 80-100 liter model is more appropriate. It’s important not to choose a model with a higher capacity than necessary, as this can lead to unnecessary energy consumption.
Here are some estimated water usage amounts by activity, so you can get a better idea of the required capacity:
- Shower: 25/30 liters per person
- Washing dishes: 5 liters of water per person
- Sink: 5 liters per person
From there, you can calculate the minimum capacity your water heater should have, depending on how many people live in your home.
3 High-Quality Materials: A Guarantee of Durability
Materials are a key factor in the durability of an electric water heater. Models with stainless steel or vitrified tanks are ideal, as they prevent internal corrosion and extend the lifespan of the appliance. Additionally, these materials improve thermal efficiency, keeping the water hot for longer without using extra energy.
Types of Heating Elements in an Electric Water Heater
When choosing an electric water heater, one of the most important aspects is the type of heating element. There are two main types:
- Shielded Heating Element: This element is directly immersed in the water, allowing for faster heat transfer. However, it is more prone to wear due to limescale buildup and its replacement requires draining the tank. It is recommended for areas with soft water.
- Enclosed Heating Element: This element is housed in a cylinder, preventing direct contact with the water. It is more durable and easier to replace, although it heats the water more slowly. It is ideal for areas with hard water.
Additionally, the power of the heating element is also crucial, as it determines how quickly the water will heat up: the higher the power, the faster the heating.
4. Temperature Control: Comfort and Precision
It is important that the electric water heater offers precise temperature control. Ideally, you should be able to adjust the temperature between 30°C and 75°C. Some advanced models come with digital displays or smart controls, allowing for more efficient and personalized adjustments.
5. Safety System: Extra Protection for Your Home
High-quality water heaters include protection systems such as automatic shut-off thermostats, pressure relief valves, and overheating protection. These features ensure that the electric water heater turns off safely in case of any malfunction, preventing accidents or damage.
6. Thermal Insulation: Keep the Heat Longer
Thermal insulation is another factor that improves the efficiency of your electric water heater. Good insulation, such as high-density foam, can reduce up to 25% of the energy needed to keep the water hot. This helps maintain the desired temperature for longer without using more electricity.
7. Maintenance and Ease of Installation
A quality electric water heater should also be easy to maintain. Look for models that include self-cleaning systems or allow easy access to internal components for regular inspections. Additionally, some heaters come with magnesium anodes that prevent limescale buildup, improving performance and extending the heater’s lifespan.
8. Electric Water Heater Repair Service in Marbella
If you have an electric water heater and notice that it isn’t functioning correctly, don’t worry. A plumber in Marbella specialized in electric water heater repairs can help diagnose the problem quickly. Although electric water heaters are durable, they can occasionally experience failures, such as a faulty heating element or a water leak. A professional can offer a quick and efficient solution, ensuring your heater works like new.
9. Professional Installation and Repair
Sometimes, even if your electric water heater is of good quality, problems arise due to improper installation or lack of maintenance.

Most problems can be resolved quickly, saving you from higher costs in the long run.
Conclusion: The Key is Quality and Maintenance
It’s not just about choosing the cheapest model, but investing in one that fits your needs and allows you to save energy in the long run. Remember, a good electric water heater should have high energy efficiency, be made of durable materials, and include proper safety systems.
