We have an old vented dryer, only takes a small-ish load (about 3kg), and has 2 settings: hot and warm (I think) - I use hot.
I usually have a wash day - there's at least one day a week where I'm not planning on going out during the day, I like to have some time pottering around each week! So I load the machine in the morning and do 2-3 loads - clothes from the week just gone, plus towels and bed linen.
Each load tends to get split for drying - basics and linen in the dryer, delicates on the airer, skirts/shirts/dresses go on hangers to dry. The airer and hanging stuff is just in our hall - we live in a small flat and have no outside space. Almost always have windows open during the day though.
The airer and hanger clothes dry quite quickly, I think as they're all quite light things and spread out, and the dryer takes 40mins-1hr per load (last 10mins is cooling). If I start in the morning around 9am I am usually done with all the washes and drying some time in the afternoon - about 4pm? I don't tend to watch the time too carefully as I'm at home doing other things and just put things to wash/dry once I realise the last lot has been done.
We only iron when a shirt or skirt/dress looks creased. Drying on hangers has largely eliminated the need for ironing.
No one ever sees washing in my house but that's just because they're never here on wash day!
