NCV = Net Calorific Value | GCV = Gross Calorific Value
max. operation temperature 90°C (opt. 95 °C), max. operating pressure 4 bar, boiler temperature range 69 – 90 (opt. 95 °C), obligatory back-end protection with mixing valve, electrical supply 400V AC, 50 Hz, 13 A

The nominal output of these boilers is achieved with the fuel according to standard EN ISO 17225-4, class A1-B1 (P16 S-P31 S, M20) for wood chips and according to standard EN ISO 17225-2 class A1 for pellets. If these fuel specifications or the stated water content levels are not complied with, the respective nominal heat outputs may not be reached. Providing the above fuel-quality requirements are adhered to, the 24 hr constant heat output is approx. 92% of the nominal heat output (e.g. NO of 220 kW x 92% x 24 hrs = 4752 kWh).
