Electric Steam Boilers

Electric steam boilers provide a clean and simple solution for generating steam without combustion. While they are not always the optimal choice for industrial-scale operations, they can be suitable for specific scenarios. We can source and incorporate electric steam boilers into larger system designs when they align with the project requirements, drawing on our expertise in package plant rooms and thermal system design.

How do electric steam boilers work?

Electric steam boilers generate steam by heating water with electricity rather than a fuel source. Resistive heating elements or electrodes transfer energy directly into the water, producing steam. This process avoids the need for burners or flue gas systems, making electric boilers inherently different from combustion boilers.

While electric boilers offer advantages such as no on-site emissions and quieter operation, they are often limited in capacity and can result in higher operating costs where electricity prices are high. Their use is typically best suited for specific applications rather than large-scale industrial processes.

Key considerations when choosing an electric steam boiler

Choosing the right electric steam boiler for your application requires evaluating a a variety of different factors:

Zero on-site emissions

Electric boilers eliminate the need for combustion, resulting in no direct CO₂ or NOx emissions. However, the environmental impact depends on the source of electricity.

High efficiency

Electric boilers operate near 99% efficiency in converting electrical energy into heat. This makes them efficient in energy transfer but does not account for the cost of electricity.

Capacity limitations

Electric boilers are generally more suitable for small to medium-scale applications due to limitations in grid capacity and energy costs.

Simplified design

With no burners or fuel storage, electric boilers are compact and require less maintenance compared to combustion boilers.

Applications of electric steam boilers

Electric steam boilers are typically found in specialised applications where low emissions, compact design, or silent operation is a priority. Common sectors include:

  • Healthcare
  • Pharmaceuticals
  • Small scale food production

 

Our expertise

While electric steam boilers are not part of our core product focus, we understand their role in niche applications. With decades of experience in combustion systems and thermal engineering, we can incorporate electric steam boilers into larger, customised system designs, ensuring they work seamlessly alongside traditional combustion systems to meet your operational goals.
