• 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

Peak Load Management

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.
