Benchmark S

High efficiency gas-fired Benchmark boilers reduce total project and lifecycle costs while delivering energy savings, quiet acoustics and easy maintenance. Their condensing heat exchanger design is built to withstand thermal shock and eliminates the need for boiler pumping equipment. Their forced draft, modulating burners operate with unmatched turndown to minimize cycling and maximize seasonal efficiency while simplifying the venting system.

Each unit features a compact footprint allowing it to fit through a standard 32" doorway to be easily installed. Removable enclosure panels support easy access to all piping and simplify lifetime maintenance. Compatible with popular EMS software, the units can be remotely controlled and provide detailed LCD diagnostics. Available in eight sizes 750 - 6000 MBH.
