Cleaver-Brooks - Complete Boiler Room Solutio

2018-8-5 · Condensing boilers can achieve efficiencies that exceed 90% because they are designed to operate with cold return water temperatures, which promote condensing of the moisture in the flue gas. In a condensing boiler, the return water must be brought back to the boiler below 130°F — coinciding with the flue gas dew point for natural gas

How High Efficiency Condensing Gas Boilers Work

In contrast, a high efficiency condensing gas boiler, with a fully modulating ebm-papst blower, is capable of running at full on, off, or any speed in between. The result is a more efficient boiler and meets the demand of the system, even when the full heat input isn't needed. Components of a high efficiency condensing gas boiler
