My sister has just had central heating put in her (council) house. She has
a very odd shaped kichen and and enquired whereabouts the kitchen radiator
would be. The 'fitter' said she couldn't have a radiator in there as
legislation says all "newly fitted" radiators (not replacements) must be
hung on an outside wall! So he put one of those fan heater/air conditioning
units above the outside door. Is this right or total bo****cks as I have
never heard this!
The "fitter" is completely wrong
If you read all the advice on central heating from official documents you
will find that you are advised to have radiators not under windows but
positioned on inside walls including partition walls.
I have built a new house which has followed these rules and I am very
satisfied with the results
I suggest your sister should write officially to the Council complaining
I had always thought that fitting a radiator on an opposite wall to a window
increased the draft
in a room, as the cold air fell off the window and was helped upwards by the
so it was a "good" thing to place it under a window - although that seems a
little odd as well as the
warm air is then trying to warm a cold window and some goes straight out
through the glass....
Paging Ed Sirett ........
At one time the thinking or lack of it was that placing a rad under a
window allowed the draught from the window to circulate the heat into
For years ever since, curtaining and open windows have cost the
householder hundreds of pounds in wasted heat.
Just having an heater on an outside wall is inviting direct heat loss
from the back of the rad to the outside wall without placing it under a
thin, leaking glass panel. Easy to see why the fitter was working for
the council. No one else would have him.
What part of the word "direct" do you have the most trouble with?
If the room is being heated the laws of thermodynamics indicate it will
also be losing heat. However if the radiator is situated on an internal
wall the heat loss will occur after it has radiated, conducted and
convected it through the building's internals.
So when a radiator is fitted to an outside wall under a window it will
lose no less heat than if placed elsewhere?
Just how dense is the wall? What difference might that make? And are

Both nice ideas, but you need the rad to be stood off the wall a decent
amount to do either. In the lounge we have to bundle the curtain up on
the window sill or cover the rad and in the bedroom we can't even do
that - the sill's too shallow. This isn't the 1st house I've lived in
where that's the case.
You'll lose a lot less though - the rad heats the inside of the wall
(feel it!) and so the temperature gradient is much greater than across a
wall at room temp.

Oh for heaven's sake. Why is it grounds for complaint? He was mistaken or
told a fib, big deal. I would accept that Sunday was Tuesday if it meant I
was getting my central heating installed for free.
