Expert Guide to Selecting and Pricing Electric Water Heaters

We have prepared everything you need to know about a high-quality electric water heater, how it works, and its key features, so you can choose the most suitable option based on your needs and budget when purchasing an electric water heater.

Electric water heaters operate in a manner similar to other types of water heaters and are used to supply domestic hot water in various locations. The main difference between electric water heaters and other types lies in their energy source, as they use electricity instead of gas, oil, or other fuels.

Electric water heaters are manufactured in wall-mounted and floor-standing models, available in various sizes and capacities. Users can select the appropriate capacity based on their hot water consumption and the size of the intended space.

Although gas water heaters are more commonly used today, there are still many areas without access to a gas distribution network. Especially in cold regions and areas outside cities, electric water heaters are considered the best solution.

How Electric Water Heaters Work

As expected, electricity is the primary energy source for these types of water heaters. A sensor is installed inside the unit, which detects water flow when a tap is opened and activates the heating element.

Water enters the heater’s tank and is heated by the heating element. Once heated, the hot water becomes available for use. When the tap is closed and water flow stops, the sensor deactivates the heating element and no water exits the tank.

Advantages of Electric Water Heaters

By understanding the many advantages of electric water heaters, you can make a better and easier purchasing decision.

Electric water heaters have eliminated many limitations associated with domestic hot water systems, especially for villas, off-grid units, or areas without gas supply. Electric water heaters are an excellent choice because:

• No gas piping is required.
• Installation is simple and fast.
• No chimney or flue is needed.
• Wall-mounted models occupy less space.
• They eliminate risks such as gas leaks, carbon monoxide poisoning, and air pollution.
• They can be used anywhere, even in remote areas without access to city gas.
• Maintenance and repair costs are lower compared to other water heaters.
• They have a longer lifespan than gas water heaters due to the absence of an open flame.

Types of Electric Water Heaters

Electric water heaters are categorized based on several factors such as power supply type, wall-mounted or floor-standing design, tank or tankless structure, and heating load. Users can select the most suitable type according to their requirements.

Based on Power Supply

Electric water heaters are available in single-phase and three-phase models. You can choose the appropriate option based on site conditions and consumption requirements.

Wall-Mounted and Floor-Standing Electric Water Heaters

Electric water heaters are produced in wall-mounted and floor-standing designs. Wall-mounted units are suitable for smaller spaces with lower heating demands, while floor-standing models are better suited for areas with higher heating loads.

Electric Water Heaters Based on Heating Load

The heating capacity of an electric water heater should be selected based on hot water consumption, area size, and application type. If you are unsure about the correct capacity, providing accurate information to a sales expert can help you make the right choice.

Tank and Tankless Electric Water Heaters

Tank-type electric water heaters are equipped with an insulated water tank. The water temperature inside the tank is continuously monitored and controlled, and when the temperature drops, the heater automatically reheats the water.

One of the main disadvantages of wall-mounted tank-type electric water heaters is tank corrosion and scale buildup over time. Therefore, reputable manufacturers apply protective coatings to the tank to prevent such issues.

Tankless electric water heaters heat water on demand without storing excess hot water.
This feature results in slower water heating and makes simultaneous use of hot water from multiple taps impossible. To ensure optimal performance, the anti-scale filter must be replaced at least once a year.

Difference Between Tank and Tankless Electric Water Heaters

The differences between these two types are as follows:

• Tank-type electric water heaters consume more energy compared to tankless models.
• Installation and setup of tankless electric water heaters are easier and more convenient.
• Tank-type electric water heaters require more installation space due to the presence of a tank.
• Tank-type electric water heaters offer better performance by supplying hot water more quickly.

Purchasing an Electric Water Heater

Always keep in mind that when purchasing an electric water heater, you should carefully evaluate the required capacity as well as the installation location and usage conditions. There are also other important factors that must be considered before making a final purchase decision.

It is recommended to note down the required information in advance. If you are unable to make the right selection, you can seek assistance from sales experts. For example, you should know the size of the unit, the number of bathrooms and restrooms, and whether the heater will be used in a cold or warm climate.

To ensure an easy and accurate selection, the first step in purchasing an electric water heater is determining the required capacity.

Difference Between Electric Water Heaters and Package Systems

Both electric water heaters and package systems are designed to heat water, but there is a fundamental difference between them.

An electric water heater is solely responsible for heating domestic hot water used for bathing, washing machines, dishwashers, and sanitary facilities. A package system, however, not only provides hot water but also heats indoor spaces through connections to radiators, fan coils, or underfloor heating systems. This feature is considered an advantage of package systems, although the final choice depends on your specific needs and application.

Applications of Electric Water Heaters

The main applications of electric water heaters include:

• Use in areas without access to city gas.
• Use in cabins or temporary units without gas piping or chimneys.
• Use in small apartments with low hot water demand.
• Use in locations sensitive to pollutants produced by fossil fuels.
• Use in areas lacking proper ventilation or open spaces such as balconies, where gas water heaters cannot be used due to safety risks.

Safety Tips for Using Electric Water Heaters

In general, electric water heaters pose fewer risks compared to gas water heaters. However, observing the following safety guidelines is strongly recommended to minimize potential hazards:

• Thermostat: One of the most critical components that helps prevent hazards. Always ensure it is functioning properly.
• Usage Intervals: Continuous operation may be hazardous. It is recommended to allow a 10-minute break after every hour of use.
• Safety Valve: Ensure that the safety valve is properly installed and operating correctly.
• Grounding Wire: Since electric water heaters rely on electricity, using a grounding wire is highly recommended for added safety.
• Empty Tank: Never operate the electric water heater when the tank is empty.
• Pipe Integrity: Regularly check the condition of the connection pipes and the heater tank.
• Cleaning the Heater: Never spray water directly onto the heater. First disconnect the power supply, then clean it using a damp sponge or cloth.
• Heater Maintenance: For installation or servicing, contact authorized representatives and use qualified technicians.
• Adequate Oxygen: Avoid installing electric water heaters in humid environments with insufficient ventilation.
• Children: Install the heater at a height that prevents children from accessing it.
• Safety Valve Inspection: Regularly inspect the safety valve to ensure it is not blocked by scale buildup and that discharged water is directed to an open area.
• Optimal Temperature: For tank-type electric water heaters, the recommended water temperature range is between 50 and 60°C.
• Emergency Situations: In case of an incident, first disconnect the power supply and then shut off the water inlet valve.
