| (1) Low temperature means for condensing boilers 30 °C, for low temperature boilers 37 °C and for other heaters 50 °C return temperature (at heater inlet). (2) High temperature regime means 60 °C return temperature at heater inlet and 80 °C feed temperature at heater outlet. (*) At the maximum flue distance, the flue length should be reduced by 1 meter for every 90° bend and 0.5 meter for every 45° bend. |
