Electro Electric Boiler EB-WO-27 is designed for multiple temperature, high temperature, and zoning applications. The EB-WO-27 has the ability to sense water temperature and maintain an accurate boiler temperature output by only energizing the electric elements for needed output (not full capacity). The EB-WO-27 also has an outdoor reset for added convience. The Electroc EB-WO-27 electric boiler eliminates extra costs associated with relays, extra temperature controls, zone boxes, etc. Our more experienced installers use t his boiler to avoid the extra cost of the above.

The front panel temperature knob allows you to simply dial in your desired output temperature and the EB-WO-27 will automatically adjust to meet your water temperature needs.
