I've just checked my envelope of booklets -
Chest freezer - 2024
washing machine - 2024
electric stove - 2021
vacuum - 2020
water heater - 2013 (replaced 1999 heater)
microwave - 2020

my 2015 clothes drier died a couple of years ago but I kept it as it is my bathroom bench! The booklet lives on the top so my executor knows it's condition. I wash twice a week, open the window wide & put stuff on the airer or the lines above the bath & use my 18" fan to help them dry. In summer they are usually dry before I go to bed, on colder days the fan goes all day & night. According to my engineer friend it uses less electricity than a dryer would.

My 4 windows are locked open about 6" as my bit of Sydney is close to the harbour & doesn't get very cold, so I've never had a heater - track pants over my winter tights & thermal tops & woolly cardigans keep me warm in our version of winter.
