And you’d still need five or six split systems to properly heat a home.

Kitchen, dining, bathroom, three or four bedrooms.

I’ve never seen a split system in a bathroom, but I’ve definitely seen freezing cold bathrooms, or bathrooms with a radiant heater on the wall or heat lamps on the ceiling, which occasionally get left on all day and destroy electricity bills.

Ducted systems almost always extend to the bathroom, and almost always cost AU$15,000 or more to install.
