Boiler Efficiency - an overview | ScienceDirect Topics

584 is the latent heat constant for partial pressure of water steam. 3. Heat loss owing to the moisture present in fuel. The fuel evacuates as a superheated vapor with moisture arriving at the boiler. Furthermore, this moisture loss is prepared as practical heat to pass the moisture to the boiling point and as superheated needs to get the steam

What temperature should a condensing boiler be set at

The dew point temperature is a measurement that determines the humidity of air and is the temperature at which water droplets form in the heat exchanger. For gas boilers, the dew point is around 55 °C. This means that the water needs to be 55 °C or lower for your boiler to maintain its efficiency. How to set the temperature on a Viessmann boiler
