High Wycombe Whirlybird Installation and Replacement

High Wycombe 6057 sits about 17km east of the Perth CBD, in the City of Kalamunda. Dave installs and replaces whirlybirds and solar roof vents throughout the suburb — fixed prices, no subcontractors, travel included.

High Wycombe is roughly 22km from the coast, which puts it well outside the reliable sea-breeze belt. Summer afternoons here run hotter and stiller than anywhere on the coastal plain, and a wind-driven turbine can sit motionless through the worst of it.

High Wycombe is largely 1980s brick and tile. Floor plans grew through the eighties and roof pitches came up slightly with them, so cavity volume per square metre is higher than on a fifties home of the same footprint. Three to four units is the usual landing point.

Where these houses catch people out is eave venting that looks adequate and is not. It is worth an actual look rather than an assumption, because it changes what the extraction can achieve.

Far inland — light, late breeze

Whirlybirds or Solar Vents in High Wycombe?

Solar, in most cases. High Wycombe sits far enough inland that wind is the least reliable thing you could power a roof vent with, and hot still afternoons are the norm rather than the exception through summer.

A solar unit sidesteps the problem entirely — it runs on the thing High Wycombe has in abundance. From $750 installed, no wiring, no electrician, and no running cost, and it is working hardest at the hottest point of the day.

If the budget only stretches to turbines, they are still better than an unventilated roof — but you should go in knowing they will be doing less here than the same units would in Scarborough. Dave would rather tell you that upfront than have you disappointed in February.
