I'm not getting this.
I'm not getting it either, Mindy. The picture of the Brits as a nation whom simple plumbing and heating technology has passed by is frankly bizarre. I honestly don't see why Angel, bless her! has to wash her hands in cold water in summer (look for the "on" button on your domestic hot water system, Angel!), or hang out her washing to dry if she doesn't want to. As you say, Mindy, tumbler dryers aren't earth-shatteringly expensive - probably not much more than the cost of a standard rail ticket from Derby to London.
In another thread there were comments about how long it takes for a Brit washing machine to do a wash. Well, mine is a fairly elementary model, and it still doesn't take much over half an hour - so, are people misreading the instructions? I suppose if their machines are plumbed-in to the cold water supply only, it could take longer, because the machine would itself have to heat the water first: could this be the reason for the long washing times reported?
Also, while it is true that mixer taps are rare in British bathrooms, there is a good reason for this. The cold tap is fed by the rising main, and therefore provides water pure enough for drinking. If it were mixed in with the hot supply. it would be meeting water that had been in stored in a tank for some time, often at a temperature beneficial to bacteria growth. You have to run cold through a mixer tap for some time before you can be sure left-over water from the hot supply is not contaminating your drinking water.
Also in another thread there were comments about there being no electricity outlets (e.g. for hair driers) in our bathrooms. Well, this is a safety thing too. Bathrooms are damp places, and our voltages twice as high as yours. Is it really such an imposition to have to dry your hair in your bedroom?
As for those who feel that living in Britain is like camping, well, I can only assume that they are living in incredibly out-of-date housing, or in very remote places, or perhaps are being made the subject of a remarkably sophisticated and complex Brit-style practical joke!
