More Info
The graphs shown below are intended to provide general guidance on the sizing of the system, and give, depending on the type of combustor, the heat output of the generator[kW] and the height of the fireplace [H], an indication of the hydraulic diameter [Ø mm] with which to construct the flue.
The purpose is to provide the characteristic curves of tendency in sizing; it is still essential to carry out the sizing calculations, even with specialized software, and with the qualified technical support staff.
