Low NOx burners help minimize air pollution formed during the combustion process, while trimming excess air coming into the boiler.

Airfoil blades on fans maximize fan efficiency. Periodically check fans and housings for dust and dirt buildup (at least semi-annually).

Variable speed drive motors or variable speed hydraulic drives on boiler forced draft fans reduce electrical costs. Analyze whether operational cost-savings offset capital expenditure.

Purchase and install premium efficiency motors. See Motorsfor more information about motor efficiency.

Increase boiler and preheater insulation.
