Istanbul is significantly harder than Sydney — a difference that has major household implications. Appliances, boiler warranties, and detergent costs will differ substantially.
Moving from Sydney to Istanbul?
If you're relocating from Sydney to Istanbul, expect visible limescale on taps and shower heads within weeks. You'll need to recalibrate your dishwasher's salt setting, increase kettle descaling frequency, and check your boiler warranty requirements. A shower filter and under-sink scale inhibitor are worth considering immediately.
