Benchmark E
- Electric boiler
- Advanced Edge Controller and mobile app
- 216 kW to 684 kW
Benchmark E is a powerful, zero-emissions electric boiler that offers the superior reliability and energy savings of the original, compact gas-fired Benchmark boiler, in addition to new technology such as Peak Load Management and Hybrid Plant capability. Featuring powerful technology that maximizes system efficiency and optimizes plant management, Benchmark E can help to effectively meet local regulations and codes on building electrification and decarbonization.
Features and Benefits

- Zero emissions and near 100% efficiency
- Durable Incoloy sheathed elements
- Integrated Edge® Controller
- Manage electricity usage with Peak Load Management
- Easy hybrid plant control and boiler sequencing
- Compact, lightweight and fits in freight elevator
- Easy service access from front and top
- Industry-leading warranty for greater peace of mind
Benchmark E lowers building peak loads and operational costs by maximizing charging time during hours with off-peak electricity rates. The Edge Controller can limit power output by using a time schedule, analog input from a Building Automation System, or outdoor temperature sensor. The SSR diode element group in the Benchmark E further enhances the effects of peak load management by providing superb low-load control.
Boiler Sequencing Technology and Hybrid Plant Capability
Benchmark E boilers come standard with AERCO’s Boiler Sequencing Technology (BST) to enable the load to be shared between up to 16 boiler units in order to maximize system energy efficiency. As individual boilers are added or taken offline for maintenance, the energy delivered is automatically adjusted to prevent fluctuations in the header temperature of the plant. Benchmark E also pairs seamlessly with AERCO’s SmartPlate® EV indirect water heater for a fully electric, vent-free heating and hot water plant solution. The built-in BST also enables Benchmark E boilers to be sequenced with AERCO’s gas-fired Benchmark boilers for a versatile hybrid plant to optimize boiler operation and energy sources. Choose either to prioritize the electric boiler to reduce building emissions while using gas to cover design load days or to prioritize the gas or electric boiler depending on local gas and electricity costs.
Advanced Edge Controller
Benchmark E features the advanced Edge® Controller, which provides precise temperature and operating controls, outdoor reset, and boiler sequencing to enhance system efficiency. It includes a large, intuitive 7" touchscreen for easy startup and diagnostics, as well as performance trending, reset schedules, and sequencing for up to 16 units. The controller supports peak load management and integrates with BACnet and Modbus communication protocols for seamless connection. In case of external control failure, it ensures fail-safe operation and is compatible with AERCO’s Benchmark gas-fired boilers and SmartPlate EV indirect water heaters.
Backed by a Superior Warranty
Benchmark E comes with AERCO’s Industry-leading warranty, including 10-year warranty on the pressure vessel, 1 year on parts and electrical elements, first year service policy, and 2 years on the Edge Controller.

Frequently Asked Questions
What is the AERCO Benchmark E electric boiler?
Benchmark E is an all-electric commercial hot water boiler designed for closed-loop hydronic heating systems. Available in five sizes from 216 to 684 kW (equivalent to ~750 MBH to 2500 MBH), it delivers zero on-site emissions and 99+% thermal efficiency.
Where is Benchmark E a good fit for commercial heating applications?
Benchmark E can be used in new construction, retrofit projects, and facilities pursuing building electrification or decarbonization goals. It operates as a standalone electric boiler or as part of a multi-boiler plant, providing flexibility for a wide range of commercial and institutional hydronic heating applications.
How can commercial buildings reduce electric boiler demand charges and peak electrical loads?
Via the integrated Edge Controller, Benchmark E offers Peak Load Management capabilities that allows operators to limit boiler power consumption using a time schedule, Building Automation System (BAS) signal, or analog input. This capability helps facilities manage electrical demand, take advantage of off-peak utility rates, and align boiler operation with site-specific energy strategies.
Can Benchmark E operate in a hybrid electric and gas boiler plant?
Yes. Benchmark E can be sequenced with AERCO Benchmark gas-fired condensing boilers using the Edge® Controller's integrated hybrid plant controls. Building owners can prioritize electric or gas-fired operation based on utility rates, operating conditions, emissions objectives, or site preferences without requiring an external plant controller.
What controls and building automation capabilities are available with Benchmark E?
Benchmark E features the Edge Controller with a 7-inch touchscreen, precise temperature control, outdoor reset, and multiple setpoint options. It also includes Boiler Sequencing Technology for plants of up to 16 boilers, integrated BACnet IP and BACnet MS/TP communications, and support for remote monitoring through a Building Automation System.
What installation advantages does Benchmark E offer?
Because it operates entirely on electricity, Benchmark E requires no combustion-air piping, exhaust venting, or fuel-gas piping. Its compact footprint also fits through a standard doorway and can be transported in a freight elevator, helping simplify both retrofit and new construction installations.
How is Benchmark E designed to maximize reliability and serviceability?
Benchmark E features durable Incoloy-sheathed heating elements, easy front and top service access, and individually replaceable elements. The boiler can continue operating if an element requires replacement, and warranty coverage includes 10 years on the pressure vessel, two years on the Edge Controller, and one year on parts, electrical elements, and service.
