Which of the following is NOT an advantage of an electric boiler?

In the context of electric boilers, it's important to understand their advantages and limitations. One of the key features of electric boilers is their efficiency. They convert a high percentage of electrical energy into heat, which makes them highly efficient when compared to some traditional fuel-fired boilers. This efficiency is beneficial for reducing energy consumption and lowering costs associated with fuel.

Another notable advantage of electric boilers is their compact size, which allows for installation in areas where space is at a premium. This is particularly useful in applications where floor space is limited.

Quiet operation is also a significant benefit of electric boilers. Since they do not rely on combustion, there are no noisy burners or exhaust fans, making them suitable for environments where noise reduction is essential.

However, water treatment is still a consideration with electric boilers. While they may have some advantages in terms of reduced scale formation compared to conventional boilers, water treatment is often necessary to prevent corrosion and maintain system efficiency, especially in cases of hard water. Therefore, saying that electric boilers do not need water treatment overlooks the importance of maintaining the water quality for optimal performance and longevity. This understanding underscores why the statement regarding the absence of a need for water treatment is not considered an advantage of electric boilers.
