Grand Designs: radiant window heating?
John Stumbles
window heating. Never heard of it before and it sounds firmly in the
league of containers for beverages of Asian-sub-continental herbal
infusions constructed of confections of sweetened South American stimulant
bean-based plant extracts. But it was apparently Belgian, which might (or
not) explain it. Anyone see it, have any more info?

Triple glazed (on that house), metal oxide coating on the inside pane with

surface. Mains power bus bars in the frames carry current to the glass and

the outer pane reflects the Infra Red radiation back into the room
Claimed heating is 20% cheaper than the 'equivalent alternative', but I'm
not sure what that is - possibly oil or electric heating as the houser seems
to be in a village so may not be on mains gas.
Presumably by heating the glass you reduce draughts caused by cooling
against the glass - so you can get by with a lower air temperature.
What surprised me was that the actual house itself didn't seem to have any
kind of privacy at all, as there was no sign of blinds or curtains on any of
the windows. Presumably putting a curtain over the heating system would be
inefficient, so I'm not sure how you would combine the heating with
curtains - fortunately the house faced over fields so privacy isn't a
problem but getting woken with the light at 4am in the summer wouldn't be
fun.

'expensive'.
Lack of privacy and excess light seem to be recurring themes in GD
houses - where the hell do you go with a migraine and urgent need for
dark room?

The dreadful acoustics would probably be the cause of the migraine...

This is surprisingly common with the houses featured in "Grand Designs".
I've seen two with liquid crystal glass that could be obscured at the
touch of a switch, but many people featured in the programme seem to
want rooms with no curtains.

You go to one of the partly underground houses featured in the series,
the one with insufficient illumination from too few light tubes. ;-)

Parent's dining room has two large windows either side of a corner,
and about once a year, something tries to fly right through.
Pigeons make one hell of a bang when they do it, and I think it's
always resulted in a broken neck. First couple of times, it was
rather alarming -- a really loud bang which we had no idea what
it was, and on going to investigate, there's this ghostly image
of a large bird in full flight on the window glass, and a dead
bird on the ground. The image on the glass is a perfect imprint
in what looks like white flour dust of the whole bird with wings
outstretched -- you can make out all the feathers and the body.
Most bizzare.
Smaller birds usually survive, and after a few minutes on the
ground with stars going round their heads, they take off again.

I thought they claimed the windows had a very low U value somehow
because of this electric heating. Was this a misunderstanding (by us
or them) or is it possible, for example, that by heating the inner
pane you remove the downward convection air flow on the inside and
thus reduce the heat transfer?
Robert

From what I understand, the U value is inherently low for the glazing
units (multiple glazing with IR reflecting layer on the outer pane, and
krypton gas filled gaps). So much so that the internal pane of glass can
heat the air inside, whilst still meeting standards for Building Regs
Part L.
With this arrangement, heat transfer at the windows will be from pane
/into/ the air, thus eliminating cold draughts from the windows.

I wonder if the heater automatically switches off when SHMBO
flings the window open? ;-)
I guess you might arrive home to find an electrocuted burglar
halfway through breaking in :-)

I saw it and wondered what the point was. If the house had curtains the
heating would be useless. I also can't see in what way electric heating
makes sense or that the heated windows are more efficient than
underfloor heating. Electric U/F heating would have been a doddle to
install if you don't mind the costs.
There are other unobtrusive heating designs such as heated skirting
board (water filled radiatiors), and underfloor heating using ceramic
tiles to spread the heat evenly. Systems which use water to transfer
heat seem to me to have the advantage that the owner can make their own
decisions about what sort of heat source to use as events change.
i.e. use gas/oil at present, but consider a heatbank + woodburner +
solar, if electric heating works out to be more economical (say if
fusion power ever appears) then put in an electric boiler.
Mike
Only because they have spent so much on their barmy projects they
can't afford any curtains.
I can't help thinking the one this week would have been much better
with plasterboard on the walls and carpet on the floor. That kitchen
they chucked in was crude and cheap looking. I've got better looking
units in my shed.

in flight stuck on theirs, don't know how effective they are at
frightening flying birds away from the windows or if they are available
here.

What surprised me more was that there is clear air between the two
levels, as the upper floor was suspended on a steel frame above the roof
of the ground floor.
Why??
Kevin McCloud said this was so that it appeared 'floating' over the
fields, but at what cost (other than £685,000 of course!)?

Fair enough, I don't really like curtains, I put with them (and in a
Victorian house with single glazed windows and such they are useful) ,
but if I was building my own that might be a different matter.
I suspect they often have some discrete blinds.
Certainly some of them have had such things.

If the room is superinsulated, the heat loss is minimal, and heat
requirements minimal. Having these radiant windows will eliminate a massive
cold front and bridge, the windows...and provide enough heat to heat the
room.

These dippy Grand Design owners build these houses for 1 reason.
They haven't got anything to talk about.
So by building such a pretentious pile of crap they will have something to
talk
to about to each other for about 3 years. After which they will discover
that they hate living in it.
Any friends that have will quickly become ex-friends because after their
friends have visited them
and endured 3 hours of the 2 prattling twats showing off......
Imagine listening to someone for hours going on about .. "We wanted it all

We wanted to create a particular ambience...

So I've noticed. YAGB - yet another glass box; I haven't bothered
watching a few of the last several progs once I saw what was being
served up, save popping back into the prog for a look at the halfway or
threequarter mark to see if anything interesting had transpired (it

Yes, apart from whatever warm air makes it upstairs through the tubular
staircase, the heat from downstairs can't benefit the upstairs.

The majority of these designs seem to be built for the views they get -
and aren't overlooked. A few have had blinds built in to the windows which
aren't obvious when open. Others might be the same.

If you can afford the plot then fine, this week's one was hardly
overlooked but there were neighbouring houses in view, such that I'd be
a bit bashful wandering out of bed to get to the shower.

You are nuts. They think them through very well and do the calulations to
suite.
You are obviously an aficionado of Ned Ludd.
No doubt you have an avocado bathroom suite and carpet on the toilet seat.
