The AERCO Benchmark 1.5 Low NOx water boiler is designed for condensing application in any closed loop hydronic system. It delivers 20:1 burner turndown to match energy input directly to fluctuating system loads to yield the highest possible efficiencies. The 1.5LN unit's efficiency actually increases as the load decreases. It can achieve 99+% efficiency when supplied with 60F return water while firing at minimum input.

Fitted with a low NOx burner the fully modulation burner maintains AERCO standards for energy efficiency, longevity, reliability and construction quality.

The BMK 1.5LN can be used singly or in modular arrangements and offers selectable modes of operation. One of more can be integrated with Modbus communications protocol to AERCO's multiple boiler management system (BMS) or a facility-wide Energy Management or Building Automation System.
