The first is a chip fork, you get it with takeaway food to eat it with. A clothes horse is used for hanging and drying clothes on and an eggcup holds a boiled egg to eat it from ...

Bowl in the sink was when we had china enamel sink’s to stop the dishes chipping it and vice versa. ❤

This is why i love you!! I knew you'd have seen the washing up bowl. I don't do it, but i'm not against it either.
If you're soaking dishes, you can remove the bowl to add cold water for cooking or a kettle. I don't think ive used one myself as an adult though.

Ive lost my radiator key, so mine haven't been bled for ages. The teapot is dying out a little with younger and even my age group, so has the cosy.
Toast racks are usually for bigger households (like yours), or hotels (usually you just toast your own bread at hotels now)

I use tea bags 98% of the time. I think my leaves were too cheap, when i did use leaves.
Egg cups are used for soldiers (strips of toast to dip into the yolk). For boiled eggs too, to save them rolling around. Its easier to peel the skin, or eat inside it. (I saw they've already been explained below)
The chip fork goes with chips in newspaper. Its traditional, and kinda saves waste. animals eat the leftovers, and the paper and wood biodegrade. Rather then us being ahead of our time, i just think it helped polluction in seaside towns where the most daily fish and chips were consumed?

Next time your radiators get serviced watch what they do. You should see them use some sort of key or a wrench to loosen a valve at the top on one side of the radiator, just enough to hear air whistling.
Once it stops whistling, a little bit of water will start to leak so you tighten the valve and you are done.
You can probably buy a radiator key at a local hardware store.

Chip fork, (for your fish and chips, pick them up from the fish and chip shop): the washing dryer rack to put your clothes on to dry, the two small cups are egg cups to put your boiled egg into, so if you have a boiled egg for breakfast, you can cut the top off your egg with out burning yourself.

Great question. The temperature of our hot taps tends to vary depending on the type of heating system.
However because heat makes things more volatile, you tend to taste the pipes in the hot water from the tap so we only use it for heating and cleaning.
preheating the water in a kettle for cooking is for 2 reasons. Saving time and it is cheaper.

The water in your pipes is not boiling water and is therefore useless. For sterilisation, you need actually boiling water in a rolling boil to make tea. Or to sterilise anything

The wooden chip forks disappeared for a few years when the Gov banned the sale of wooden utensils due to the belief that they would harbour germs.
Finally it was pointed out that wood has its own natural antibacterial properties, so now we have the original biodegradable disposable forks back in the chippies.
If wooden utensils were a problem I think our species may have noticed during the thousands of years we used wooden spoons and bowls.

Yes we have hot water from the tap, but it’s not boiling hot for a cup of tea. You waste so much hot water while you wait for it to heat up in the pipes. A kettle so much quicker. You can clear your dinner plates of leftovers,and the kettle will boil before you have finished.

Before tea bags everyone had a tea caddy and spoon.

A full kettle, around (1 litre) 2 pints will boil in less than 2 minutes. Used for everything she said AND I use mine to cook boiled eggs.  Wooden chip fork, Clothes dryer and Egg cups for boiled eggs.

If your The water is that hot; you are wasting energy trying to cool it down. Try turning the thermostat down on the boiler to 104f, if fitted. Hot water from the tap will not be boiling unless you have an expensive Cooker tap with its own heating unit. It will not sterilise anything.

I use a tea towel folded in half and wrapped around my coffee pot so it stays hotter longer.
Shame nobody makes a coffee cosy.
We also have decorative toilet roll cosies, but they are more common in houses where they like to decorate everything.

Keys are not used on radiators anymore. I didn’t see hardly any radiators with keys back in the late 70s early 80s. The radiators in the house i grew up in didn’t have keys on radiators. To put my radiators on i just keep pushing a button on a box upstairs and the one downstairs until I hear a noise and that tells me that my house will be nice and warm in a number of minutes, my house was built in 2014 and I moved in in June, a block of flats used to be on the site.  When I was in my last year of middle school (September 1986-July 1987, I started middle school in 1983 this is the year the late Diana Princess of Wales opened Grimsby General Hospital which was the first hospital to be named after her) in December 1986 it snowed and it was deep close to the first school I went to between 1979-1983 I didn’t go back in until it melted majority of people in my class didn’t go in only a few were in school.

Now there's an idea for you...Tea & toast in the Cotswolds.  You could try some marmalade on your toast.  Not familiar with eggcups, wooden chip forks, or foldable metal drying racks?

Radiator Keys are used by people who have a Gas central heating system.

Nice one young lady. What no Egg Slicer, Heavy Duty Metal Egg Slicer Cutter for Hard Boiled Eggs.🤣Keep safe young lady.

Tea cosys, haven’t had one of them since my nana was alive,, tea bags are the thing nowadays.

The first of the 3 mystery items I can't tell you about because my vision is not good enough when I can't actually tell what is shown that and the second I have never seen in my life so assume it's something I don't use in London or something she found in some. Speciality shop or something. But I have no idea what it is but the third.  Shows egg cups   You boil your eggs for breakfast and you put one in each egg cup and then you use a spoon to hit the top until it breaks and then you use the adding of the spoon to peel V eggshell off and you cut or bite off the top of the egg. We civilised chaps do it with a spoon. But some people use an eye for just.  Savagely rip into it with their teeth. And then you can dip your little toast soldiers into it. Which are pieces of toast covered with butter and get all the running yolk all over the touch.

Bleeding the rads is a basic DIT maintenance task. Any boiler work must be done by a qualified Gas Safe technician. Anyone else will risk prison if their actions cause an explosion or injury. Nobody leaves tea in the pot to stew for a long time. Keeping it hot for longer is one thing, but if you leave it too long, it stews and tastes terrible. For that reason, tea left in a flask is an acquired taste.
