What is a main disadvantage of using an electric boiler?

The option indicating high comparative cost of required electricity is a significant disadvantage of using an electric boiler. Electric boilers rely on electricity as their sole source of energy, and depending on local electricity rates, the operational costs can become quite high compared to other heating methods, such as natural gas or oil. This can make electric boilers less economically feasible for large-scale heating needs or in regions where electricity prices are particularly steep.

Electricity can also be subject to fluctuating prices, which adds an additional layer of financial unpredictability for users. While electric boilers are often more straightforward to install and maintain than their fossil fuel counterparts, the ongoing operational expenses tied to electricity consumption can be a crucial factor in determining the overall cost-effectiveness of using such systems in heating applications.
