    Designed for larger hydronic heating applications, our Industrial Electric Boilers series boilers offer many new features. Available in many voltages(208V, 240V, 480V, 600V) and capacities(204,000 BTU/h to 1,023,900 BTU/h), the temperature sensing, relay staging and vessel configuration offer quiet operation, minimal relay cycling, consistent temperature output and most of all product reliability. Safety is one major benefit of these boilers. Several state electrical jurisdictions are requiring the Bender Insulation Monitor device (ground fault) for increased operating safety, personal protection and reliability of the boiler. Secondly, there are individual circuit breakers for each heating element, further increasing the safety and reliability of our boilers. Each boiler also includes built-in digital supply, return, and outdoor temperature sensors, enabling you to internally set and maintain the correct system design temperature, simplifying the installation process.
