The electrode boiler is a high-voltage, jet-type electrode steam boiler that utilizes water as a resistor to conduct electrical current and create heat to generate steam.


Cleaver-Brooks electric boilers use electricity as an energy source for zero carbon footprint and zero site emissions, ideal for meeting emissions reduction or decarbonization goals. Electric boilers are also nearly 100% efficient, meaning all energy delivered to them is converted to steam or hot water.

The Cleaver Brooks electrode boiler design is a fully packaged product which includes fully automated PLC controls, circulating pumps, and trim. This boiler technology has been in use since the early 1930s, and is becoming an excellent option for users needing to reduce carbon dioxide (CO2) emissions. Boiler water conductivity is automatically controlled. Since conductivity can be maintained at high levels, surface blowdown can be reduced compared to other designs. Reduced surface blowdown improves overall system efficiency. Boiler output is modulated using a shield gate design, which ensures consistent boiler performance by keeping water pressure even up and down the internal nozzle stock. This eliminates water splashing inside the boiler and ensures efficient circulating pump performance.
