In one of the rooms in my house, there is a radiator next to the door
not as I would prefer under the window. I want to move it when we
decorate the room, but my wife thinks that it would be better left where
it is so we can put a table under the window (actually it has a computer
on it and the blinds are drawn as soon as the sun comes out).

Can anyone suggest any reasons one way or another so I can make my
arguments or take the less work option?

thanks

If the spaghetti behind your computer is anything like mine, maybe not a
good place for a rad.

From what I can remember the old way was to put the rad under the window
because windows weren't completely airtight so any draft coming in would
help spread the warm air from the radiator out into the room.

Now that double glazing has come about virtually no drafts come from the
window so there is no advantage putting it under one. I'm not sure if
putting the rad at the door has the same effect with draughts coming through
the doorway. I would guess they are just put there as it is much easier when
installing.

We have just had our central heating replaced and the installers put all but
one at the doors. When they first suggested putting them there I wasn't that
enthusiastic but in hindsight it frees up the window wall. Its not as if
furniture would be placed next to the door where a radiator is anyway?

Is there an outside wall / internal wall issue? I was always given to
understand (and treat that with the circumspection that it deserves) that
radiators were best placed on internal walls.

Curtains.

Long ones cover up a radiator - so you are forced to choose between
shorter ones (or none, blinds, etc.) or longer ones and inhibiting heat
output from the radiator. (You might actually find the heat comes out of
the radiator but largely heats the window.)

Does your wife fancy the table for another object?

I've just done a reccy - and only 4 of my 11 radiators are under windows.
Another is on an outside wall which doesn't have a window, but the majority
(6) are on inside walls.

I think the best solution is to decide the most convenient location with
regard to furniture and pipework - and not worry to much about windows. It
could be argued that if you heat up an outside wall by putting a radiator
next to it, you'll actually *increase* the overall heat loss, and thus
increase your fuel bill.

We don't have double glazing - but that's another issue, mainly
revolving around the fact that we don't like the look of any but the
most expensive ones, and also like the faceted appearance of the
separate panes in the leaded glass. Secondary glazing possibly.

We do have cavity wall insulation.

My understanding is that if the rad is next to a window, then the
convection currents provide a warm air curtain by the window, and get
deflected mostly back into the room. When put opposite the window (as it
is) the currents actually tend to take the heat out.

We would have sill length curtains which ever we do and as to furniture,
we have a bookcase that would do just fine where the radiator is
currently, and would move the desk with the computer if the radiator
went under the window.

The theory is, that a radiator under the window counteracts the cold
drafts that would otherwise occur in a room. Basically, a window
(especially non DG) is the cold spot in a room; the radiator the hot
spot. Place them together and you eliminate those cold drafts around
the feet that would otherwise occur - the cold air from the window
would sink to the floor, chilling feet. The hot air from a radiator
somewhere else in the room would just rise to the ceiling, and not
really effect that cold air near the floor.

In our house there's furniture under windows. I wouldn't want a radiator
behind the furniture. The only place where there's a radiator under a windo
is in this room, where my desk is in front ot the window and the radiator
(very occasionally) keeps my legs and feet warm. that's the exception which
proves our rule.

Quite.

Far too complicated for me Mary. Plus any job I do takes weeks (if I can get
away with it) and I doubt my wife would put up with that mess for that
length of time ;o)

Doesn't really.

If you want an acceptable room temperature close to the window then you
have to heat the far side of the room higher than you would if your heat
source was between the cold spot and the rest of the room. I don't
suppose you can get an absolutely even temperature distribution across
the whole room even with underfloor heating but with radiators you get
the worst case scenario if you put them on an internal wall and as far
away for the window as possible.

For the installer of course putting radiators back to back on the
opposite sides of an internal wall rather than round the periphery of a
house can make installation much easier.
