Ducted in West Hoxton homes

Ducted in West Hoxton starts with the roof. Middleton Grange and Len Waters Estate homes have low-pitched roofs, often dark metal or black concrete tile, on closely spaced trusses, so the fan coil goes in near the upstairs hatch where it can be reached for service, and every duct run is insulated and kept as short as the truss layout allows, because a cavity that reaches 60°C will cook any bare or poorly routed duct. The upstairs bedrooms are fed from above, and the ground floor living, kitchen and any downstairs bedroom are served through a bulkhead along the hallway or a dropped ceiling section. We zone upstairs and downstairs separately as a minimum, and on the bigger homes the master retreat gets its own zone so it can run alone overnight.

Sizing has to respect the solar load rather than the floor area. Minimal eaves and north or west glass on the living areas mean the afternoon gain in a Len Waters Estate home is well above what a similar floor plan would see in a shaded older suburb, so we design to the real numbers and avoid the undersized units some builders put in to hit a price. The condenser is chosen slim enough for a 900 mm setback, kept clear for airflow and pointed away from the boundary. Running cost is roughly $1–$2 per hour whole-home, and because most West Hoxton households run the bedroom zone overnight and the living zone through the afternoon, the summer bill is usually less than the two or three wall splits they replaced.
