Three whirlybirds were replaced with two solar powered SAV20 roof vents, each solar vent extracts 2718 cubic metres an hour, that’s near 5500 cubic meters between them.
Together they are a bit of an over kill tho owner stated that the heat inside the lower pitched large home was very hot, so this will drop the roof temperature dramatically and therefore reduce the living area temperature substantially in summer.
These SolarArk roof vents are second to none, no power required, turn on when temp hits 24deg, only working when needed.
Large three year warranty and definitely top of the range.
