3 TECHNICAL AND DIMENSIONAL CHARACTERISTICS
3.1 DESCRIPTION
Wood is an alternative source of energy
and it is also precious; therefore, use it in
the best way using suitable technologies for
combustion.
Iron cast and traditional combustion wood
boilers
BPI-Eco are designed to ensure
maximum thermal yield optimising draught.
The boilers are in compliance with PAD
Directive 97/23/EEC and Standard EN
303-5.
