Whirlybird Installation in Bassendean, Perth

Dave works right across Bassendean and the wider Town of Bassendean. The suburb sits about 11km north-east of the Perth CBD — close enough that travel is always included in the quoted price, same as everywhere else in the metro.

16km inland puts Bassendean at the far edge of the sea breeze's reach. Hot, still afternoons are the norm through summer here, and that is precisely the condition wind-driven whirlybirds handle worst.

Most of what Dave works on in Bassendean is character homes with steep tiled roofs. Older homes here were built before insulation was standard and often before sarking, so the roof cavity behaves differently to a modern one — it heats fast but also sheds heat readily once you give it somewhere to go.

What holds them back is almost always the eaves. Narrow originals, or later work that boxed them in, leaves the cavity with no reliable way to draw replacement air. Adding eave vents alongside the roof units is usually money better spent than a fourth turbine.

Far inland — light, late breeze

Whirlybirds or Solar Vents in Bassendean?

Solar, in most cases. Bassendean 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 Bassendean 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.
