•
An automatic heating boiler up to 500 kW rated
capacity requires a minimum buffer volume of
25 litres per kW rated capacity.
Hence, a wood chip boiler with 100 kW needs a
minimum buffer volume of 2500 l (=100x25).
However,pellet boilers up to 70 kW rated
thermal input are exempt from this regulation.
