a. High-temperature regime means 60°C return temperature at heater inlet and 80°C feed temperature at heater outlet.
b. Low-temperature regime means for condensing boilers 30°C, for low-temperature boilers 37°C and for other heaters 50°C return
temperature.
(*) The yield data have been calculated using the higher heating value.
