95% efficient to 99% maximum Are all efficiencies created equal? Unfortunately, no. Many manufacturers, including Harsco, certify boiler efficiency using third party testing standards. However, test conditions rarely occur during normal operation. To truly compare one boiler’s efficiency to another, it is important to consider normal operating conditions. The charts shown in this brochure illustrate the efficiency you can expect under real world conditions. Efficiencies shown are thermal efficiencies (input vs. output using a flow rate corresponding to 40°∆T at full output.

MACH® C2000–C1500 Our Large Heat Engine 96% efficient to 99% maximum It’s all about system design. Purchasing a high efficiency condensing boiler is just the beginning. Condensing boilers that operate above 120°F return water temperature do not condense. Therefore, to truly take advantage of a condensing boiler’s efficiency benefits, such as significant fuel savings, the system must be designed with a return water temperature of 120°F or less. Harsco customers have saved 25% or more on fuel costs with MACH® condensing boilers.
