An electric boiler system is highly efficient thanks to the direct conversion of electricity into thermal energy that produces an almost 100% efficiency rate. Compared to normal boilers an electric boiler operates without using combustible fuel such as oil or gas. Electric boilers use electricity to generate heat for your application. Diesel fuel and gas burners on boilers require a fuel supply line, and a tank if diesel, propane, or heating oil is used. Diesel and gas boilers require a chimney and roof penetration to exhaust harmful CO and other emission products. Gas burners are more expensive than fuel burners, but all require periodic maintenance and tuning. In some areas, by law, you must pay a state inspector or independent testing agent to verify combustion emissions on a regular basis.
Electric boilers do not require tanks, fuel lines, chimneys, roof openings, or expensive combustion inspections. Reimers Electra Steam builds hot water and steam electric boiler. Just connect electric power, pipe the outlet and return lines, and it is ready to use.
You hear about electric water heaters (hydronic) too: it is similar but not the same as an electric steam boiler. Reimers can provide models that heat water up to 200F or they can provide models to generate steam up to 135 psi. Electric Hydronic Boilers Electric Steam Boilers
