The Pros and Cons of Electric Boilers

The conversation around heating solutions for our homes and businesses is evolving as we move towards a more sustainable future. Electric boilers have emerged as a popular alternative to gas or oil-fired systems, providing an eco-friendly way to keep your space warm. However, like any technology, electric boilers come with their own set of advantages and disadvantages. In this blog post, we’ll explore the pros and cons of electric boilers to help you make an informed decision.


  • 1. Energy Efficiency Electric boilers convert almost all the electricity they use into heat, boasting an efficiency rate of 99-100%. This is considerably higher than most gas boilers, which typically operate at around 89-95% efficiency.
  • 2. Environmentally Friendly Electric boilers produce zero on-site emissions, reducing your carbon footprint. When paired with renewable energy sources, such as solar or wind power, they can be an entirely green solution.
  • 3. Easy to Install and Maintain Electric boilers are generally smaller and lighter than their gas counterparts, making them easier to install. They also have fewer moving parts, which translates to less maintenance and a longer lifespan.
  • 4. Safer Operation Unlike gas boilers, electric models do not emit carbon monoxide or pose a risk of explosion, making them inherently safer.
  • 5. Space-Saving Many electric boilers are compact and can be wall-mounted, saving valuable floor space in your home or business.
  • 6. Quiet Operation Electric boilers are typically quieter than gas boilers, which can make a significant difference in your comfort, especially if the boiler is located near living or sleeping areas.


  • 1. Higher Running Costs Electricity is generally more expensive than gas, so operating an electric boiler can be costlier in the long run, especially in colder climates.
  • 2. Limited Heat Output Electric boilers are generally better suited for smaller spaces or moderate heating needs, as they may struggle to heat larger homes efficiently.
  • 3. Dependence on Electricity If there’s a power outage, an electric boiler will stop working, leaving you without heat. Gas boilers, on the other hand, can continue to operate during a power cut.
  • 4. Upfront Costs While they’re cheaper to install, the initial purchase price of a high-quality electric boiler can be quite steep.
  • 5. May Not be Entirely Green If the electricity used to power the boiler comes from fossil fuels, then the environmental benefits are negated.

Electric boilers offer a compelling mix of advantages, from high efficiency and low emissions to easy installation and safe operation. However, they also present challenges, including higher running costs and limitations in heating capacity. Before making a decision, consider your specific needs, the size of your space, and your long-term financial and environmental goals.
