MODEL BMK-2.0 GWB
TECHNICAL DATA
AERCO Benchmark (BMK) Gas Fired Hot Water Boiler System
The AERCO Benchmark Water Boiler is a true industry advance that meets the needs
of today’s energy and environmental concerns. Designed for application in any closed
loop hydronic system, it relates energy input directly to fluctuating system load, yielding
seasonal efficiencies as high as 95%. Its efficiency actually increases as the load
decreases due to its unique inverse efficiency curve. The boiler can be used singly or
in modular arrangements for inherent standby with minimum space requirements.
Venting flexibility permits installation without normal restrictions.
The advanced electronics of each boiler module offer selectable modes of operation for
temperature control. (see reverse side)
Regardless of the mode of operation, the load tracking capability of every unit delivers
the ultimate in energy control through energy input modulation with a 15:1 ratio while
meeting all load demands.
