The boiler meets Class 5 requirements for heat effi ciency and gas emission as defi ned in PN-EN 303-5: 2012 provided that
the boiler is installed in a central heating system with a buffer tank.
Minimum buffer tank capacity: V
• V
– buffer tank capacity in litres;
Sp
• Q
– nominal heat output in kW;
N
• T
– fuel combustion time in hours;
B
• Q
– building heat load in kW;
H
• Q
– minimum heat output in kW.
