hydro-pressure gas boiler flue height

Flues - an overview | ScienceDirect Topics

Flue height Raising the height of a flue increases the flue draft but also adds to the pressure loss due to friction. The net effect is that increasing height is very beneficial for short flues but has progressively less effect as the height is increased. With very tall flues there can be a reduction in flow rate due to excessive heat loss.
