About this file
This document is a technical data sheet for the AERCO Benchmark E Electric Boilers, produced by AERCO, a Watts Brand. The Benchmark E is an electric hot water boiler designed for closed loop hydronic systems, ranging from 216 to 684 kW (750 to 2500 MBH equivalent). Key features include an Edge Controller, Boiler Sequencing Technology that can manage up to 16 units, hybrid plant control capabilities, and peak load management. The boiler produces zero emissions and offers design flexibility with various control options including constant setpoint, outdoor reset, remote BAS setpoint, and analog signal input.
The specifications show the boiler is ASME Section IV rated for 150 PSG at 250°F, with models ranging from 216 kW to 684 kW. Standard features include a 10-stage sequencer, one modulating element group, variable primary flow capability, and a compact footprint that can fit through standard doors and freight elevators. The Edge Controller provides a 7" touchscreen, precise temperature control, on-board Boiler Sequencing Technology (BST), hybrid boiler plant controls, and integrated communication protocols like BACnet MSTP/IP and Modbus RTU/TCP. The boiler has a temperature control range of 50°F to 230°F and an ambient temperature range of 0°F to 130°F, with a 10-year pressure vessel warranty.

Technical Data Sheet
Benchmark E 216-684 kW with Edge Controller Electric Boilers (Benchmark 750 to 2500 MBH equivalent) The AERCO Benchmark® E (BMK E) hot water boiler is designed for any closed loop hydronic system. Just like our Benchmark condensing boilers, this unit is packed into a small footprint that fits through a standard door and can be transported in a freight elevator.
Benchmark Exclusive Options:
| • | Edge® Controller |
| • | Boiler Sequencing Technology* – manage up to 16 BMK Es with the |
Edge Controller
• Hybrid plant control – sequence Benchmark and Benchmark E together without an external controller
• Peak load management* – manage electricity usage by limiting power output
Energy Efficient Since the BMK E uses electricity, it produces zero emissions. Peak load management comes standard to lower building peak loads and take advantage of off-peak electricity rates*.The Edge controller can limit power output using a time schedule, analog input, Building Automation System (BAS) point, or outdoor temperature sensor, accommodating for great design flexibility.
Hybrid Boiler Plant Capability* The BMK E can be sequenced together with Benchmark gas-fired condensing boilers, allowing two highly efficient products to work together.
The hybrid boiler plant can prioritize gas or electric to best suit customer needs, helping lower operating costs and building emissions. Boiler status can be directly displayed on the unit in real time or be remotely monitored via BACnet.
Application and Plant Design Benchmark boilers can be used as individual units or in modular arrangements. In addition to controlling the boiler according to a constant setpoint, outdoor reset schedule, analog input or BAS point, one or more units can be integrated via Modbus communications protocol*. For boiler plants ranging from 2-16 boilers, AERCO’S built-in Boiler Sequencing Technology (BST) can be utilized*. In addition, the Benchmark with Edge control has integrated solutions for multiple BAS protocols.
