What is a heat exchanger in a boiler? | Viessmann

A boiler works by using hot gas to heat water - and a heat exchanger is what allows this to happen. As the gas is heated, it begins to rise. When it rises, it reaches the heat

Boiler Efficiency - an overview | ScienceDirect Topics

Boiler efficiency can be calculated using ASME Performance Test Codes (PTC). PTC 34 is used for waste combustors with energy recovery using the boiler as a calorimeter. Using this method, the heat outputs, losses and credits must be calculated. Heat credits correct the efficiency to standard ambient conditions, such as air temperature.
