Heat Recovery/Extract Fan Ductwork

Question

Is their anyway I can add a heat recovery unit/extract fan whilst drawing/sizing ducts in Netsy?

Hi Liam - The System Marker is used to indicate the extract fan and this must be placed at the start of the system. If you are wishing to accommodate the potential resistance offered by a heat recovery unit you can use a user defined fitting to indicate this. Regards,
