Pulse combustion condensing hydronic boilers have a combustion process that is naturally aspirated and does not require a blower motor for operation. An assist fan is used for pre-/post-purge only and turns off once combustion has been established. The boilers require electricity only for purge cycles, powering fuel valves, controls, and other safety features; the Pulse combustion process itself requires no electricity. According to the manufacturer, because the electricity consumption of the boilers is so low, it is very easy to integrate the units into various green building applications, including those that use solar, wind, or other alternative sources of energy. The boilers are available in models that range from 300,000 to 2 MMBtuh input. The boilers are configured to meet low-emission requirements, and a modulation control system provides precise temperature control with infinite turndown capabilities throughout the entire firing rate range.
