Electric water heaters have gained popularity due to their convenience and energy efficiency. However, there are several drawbacks to this type of water heater that you may not be aware of. Here are six reasons why more and more people are choosing to opt for alternative options, such as gas water heaters.
1. Slow Heating Process
In today’s fast-paced world, waiting can be a challenge. Electric water heaters require users to turn on the power at least 20 minutes in advance to reach the desired temperature. Forgetting to do so results in an even longer wait for hot water. On the other hand, gas water heaters provide instant heating without the need for pre-boiling or waiting.

2. Limited Hot Water Supply
Electric water heaters are storage-type heaters, which means they heat water after it enters the tank. Consequently, when the tank runs out of water, you’re left without hot water. A 60-liter electric water heater typically provides enough hot water for only about 30 minutes of showering, causing inconvenience for larger families. In contrast, gas water heaters offer an unlimited supply of hot water.
3. Poor Temperature Control
One of the main drawbacks of electric water heaters is the difficulty in controlling water temperature. These heaters often heat water to temperatures as high as 60°C or more, posing a scalding risk. Users have to constantly adjust the hot and cold water mix, which can interrupt the shower experience and affect relaxation. Gas water heaters, on the other hand, provide precise temperature control for a more comfortable showering experience.
Additionally, electric water heaters often fail to maintain a stable water temperature throughout the shower. As hot water is used, the temperature in the tank gradually decreases, resulting in fluctuating water temperatures. Gas water heaters, however, can supply a continuous flow of hot water at a stable temperature.
4. Bulky and Space-Consuming
With bathrooms becoming increasingly compact, the large size of electric water heaters can be a significant drawback. These heaters are typically installed in bathrooms to reduce the distance between the heater and the faucet, maintaining stable water temperatures and reducing waiting times. However, their bulky design, especially in larger capacities, can be cumbersome and may not suit all bathroom layouts.
In contrast, gas water heaters are known for their compact size, taking up only a fraction of the space required by electric heaters. They can be installed in the kitchen or even concealed in a cabinet, saving space and enhancing the aesthetics of your home.
5. Prone to Hygiene Issues
Electric water heaters with storage tanks can develop hygiene issues over time. The water stored in the tank for extended periods can lead to the formation of sediment and scale buildup, especially if the heater is not used frequently. This buildup can affect the efficiency of the heater and may even cause damage to its components.
The high heating temperatures of electric water heaters also contribute to the rapid formation of sediment. When the water temperature exceeds 55°C, the rate of sediment formation increases significantly. In contrast, gas water heaters typically operate at lower temperatures, reducing the likelihood of scale buildup.
Additionally, the heating element in electric water heaters is immersed in the water, which means that any sediment buildup will accumulate on the element, reducing its efficiency. The anti-electricity coating at the bottom of the tank and the internal pipes are also susceptible to corrosion and deformation over time, leading to potential blockages.
6. Inability to Provide 24/7 Hot Water
To have continuous hot water with an electric water heater, it needs to be powered on 24 hours a day. This not only increases electricity costs but can also reduce the lifespan of the heater and pose electrical safety risks. Gas water heaters, on the other hand, provide instant hot water whenever you need it, without the same concerns as electric heaters.
