Heat recovery depends on operating conditions
A condenser recovers additional heat from flue gas when operating conditions allow condensation. Return-water temperature, fuel composition and system arrangement all matter. Ask for performance at your design and seasonal operating points.
Read the efficiency basis
Efficiency figures based on lower heating value cannot be directly compared with figures based on higher heating value. State the fuel basis, water temperatures, load and test standard when requesting or comparing performance data.
Include condensate and materials
Specify condensate drainage, neutralization where required, suitable flue materials, and maintenance access. Select the whole heating system rather than an isolated efficiency headline.
