Benchmark Standard 1500 and 2000

For more than twenty years, AERCO's Benchmark commercial condensing boilers have set the bar for high efficiency and have been considered the gold standard in hydronic heating. Benchmark 1500 and 2000 boilers provide reliable space heating for a wide variety of applications while delivering the highest burner turndown and seasonal efficiencies in the industry. Easy to install and service, the Benchmark is a powerful boiler in a compact footprint durably built with a 439 stainless steel heat exchanger for longer product life.

Use our pre-populated autoCAD schedules with detailed notes to ensure you get the exact product you want.

Features and Benefits

To minimize emissions, Benchmark boilers are fitted with a low NOx burner whose emissions will meet the most stringent NOx and CO requirements. The fully modulating burner also maintains AERCO standards for energy efficiency, longevity, reliability and construction quality.

​Benchmark boilers can be used as an individual unit or in modular arrangements and offers selectable modes of operation. In addition to controlling the boiler according to a constant set point, indoor/outdoor reset schedule or 4-20mA signal, one or more units can be integrated via Modbus communications protocol. For boiler plants ranging from 2-8 boilers, AERCO’S built-in Boiler Management Sequencer* can be utilized. For heating plants greater than 8 boilers, the ACS (AERCO Control System) provides the right solution. Likewise, Benchmark systems can be easily integrated with a facility-wide Energy Management or Building Automation System.

Reliability

First introduced in 1997, the Benchmark boiler is one of the first high-efficiency products available in the U.S. The market leader for the last decade, several thousand Benchmark units have been installed throughout North America and have continued to operate flawlessly season after season. Their performance proven reliability can be credited to:

Superior Construction Materials
A 439 stainless steel heat exchanger offers even longer life and improves longevity with a simplified design that has only two moving parts.

Advanced Design and Components
AERCO’s patented air/fuel delivery system and fully modulating burner reduces cycling losses, as well as wear and tear.

Warranty
AERCO stands behind its products. The heat exchanger in the Benchmark boilers has a 10-year full (non-prorated) warranty.


Installation Advantages

Venting Versatility
Benchmark products provide a number of venting options. Sidewall, through-the-roof, and ducted combustion capabilities (direct vent), approved for venting with Polypropylene, or AL29-4C materials, are all available and provide broad installation flexibility and savings.

Space-saving Design
All Benchmark products are delivered as a single, fully assembled unit. Its small footprint, doorway size, and quiet operation make it ideal for both new construction and retrofit applications.

Zero Side Clearance
The redesigned Benchmark can be serviced via the front or top of the boiler, as well as the side. This flexibility allows units to be configured side-by-side.


Environmental Advantages

The Greenspec® Listed Benchmark boilers are perfect for “green” designs. Their small footprint, flexible venting/piping options, high efficiency, and lower operating costs can help facilities earn LEED points. Benchmark has been designed with environmental advantages:

Low NOx burner
Benchmark boilers are fitted with a low NOx burner whose emissions consistently meet the highest regulatory standards. Ultra low NOx (9 ppm or less) calibrations are available.


Advanced Controls 

C-More
Efficiency and operation is further optimized via the C-More Control System. Intuitive, advanced, and simple to operate, C-More combine’s temperature and operating controls, combustion safeguards and fault enunciator functions – all at your fingertips! Benefits include:

  • Simplifies diagnostic troubleshooting
  • Full integration with BAS and EMS systems
  • Supports remote monitoring and control
  • Ensures fail-safe boiler operation (if external building controls fail).

Boiler Management System
Benchmark boilers can be used as an individual unit or in modular arrangements and offers selectable modes of operation. In addition to controlling the boiler according to a constant set point, indoor/outdoor reset schedule or 4-20mA signal, one or more units can be integrated via Modbus communications protocol. For boiler plants ranging from 2-8 boilers, AERCO’S built-in Boiler Management Sequencer can be utilized. For heating plants greater than 8 boilers, AERCO’s ACS (AERCO Control System) provides the right solution. Likewise, Benchmark systems can be easily integrated with a facility-wide Energy Management or Building Automation System.

Options and Accessories

Accessories

AERCO Condensate Neutralizer Kit 
Ideal for neutralizing condensate from condensing boilers and furnaces operating on natural gas or propane.

AERCO Control System (ACS) 
Optional multiple unit controller recommended for installations of eight or more boilers to maximize operating efficiency.

Butterfly Valve
Designed to meet the needs of HVAC and commercial application requiring bubble tight shut-off for liquids. Typical applications include boiler isolation, chiller isolation, cooling tower isolation, change-over systems, air handler coil control, bypass and process control applications.

ProtoNode Gateway 
Optional accessory supports boiler or BMS integration with BACnet, LonWorks and N2 systems.

Integration Panel - BST Modbus 
Allows for automatic BST Master-function transfer to the next available unit in the event the original Master experiences a control panel or communication failure.

Sentinel Products 
Compatible with all materials found in a hydronic loop, these chemicals offer overall protection of a heating system from sludge, scale, corrosion, and freeze conditions.

Secondary Low Water Cut-Off (LWCO) 
Where required by building code. Secondary LWCO must be installed external to boiler.
