Now, I don't know about you lot, but for me shutting the windows on a
bloody hot day like today is the LAST thing I would consider to keep my
house cool with!!


Then you need to take heed of the Met Office's advice and my earlier
comments in another thread. To save you searching for it I'll repeat the
advice. Have all the windows open during the coldest part of the day
(around dawn) to cool the house down. If you can safely leave some windows
open overnight this will help. When the external temperature rises to a
point near where no further cooling of the house can be achieved, probably
by nine o'clock, close all the windows and close curtains on the sunny side
of the house. This way you should be able to maintain a temperature several
degrees lower than outside. Opening a window in the middle of the afternoon
will only heat up the inside of the house. If you want to feel the
refreshing effect of air movement, get a fan.

The temperature in my house is currently 26 downstairs and 28 upstairs. I
have no windows open. A couple of hours ago, according to Martin Rowley,
the external temperature near here was 32 degrees and I suspect it's higher
now.
