The Seattle Sheraton hotel partnered with MacDonald-Miller to address boiler system inefficiencies that were causing temperature fluctuations and increased energy consumption. The primary goal was to improve system stability and maximize utility savings by modernizing the hotel’s boiler plant controls.

MacDonald-Miller delivered a state-of-the-art boiler optimization solution featuring Limpsfield burners paired with Autoflame linkage-less controls. This advanced system provides precise setpoint control within one degree, superior turndown performance for low-fire capability, and coordinated communication between burners to stage boilers efficiently as demand increases.

As the exclusive dealer for Autoflame and Limpsfield in the Pacific Northwest, MacDonald-Miller was uniquely positioned to deliver a high-efficiency, fully integrated solution that improved comfort, reduced fuel use, and enhanced the overall performance of the hotel’s mechanical plant.
