Commercial Products

SIME's line of commercial high efficiency gas boilers gives one all the advantages of 316 stainless steel copper heat exchanger technology plus the benefits of a sealed combustion system. 

Every SIME commercial model offers four major advantages:  higher efficiency, smaller footprint, smaller vent diameters and multiple venting options. 

Our models offer dollar stretching proportional firing that provides a measured response to the demand for heat as much or as little as needed. 

Outstanding Thermal Efficiency 

SIME boilers offer a remarkably high 97% thermal efficiency.  This means that $0.97 out of every fuel dollar goes into heating the water, dramatically reducing the operating cost of the equipment.  SIME achieves this efficiency through the combination of an advanced fan assisted combustion system and highly durable 316 stainless steel exchanger.  A time tested proven combination. 

The heat energy from the combustion process is transferred to the water as it passes through the 316 stainless steel heat exchanger.  The sealed combustion design eliminates external heat losses, this means that the energy dollars heat the water, not the mechanical room.  It also ensures that the boiler jacket stays cooler, providing greater safety, and requires less clearance from combustible walls.
