Now reaching the end of some works to my house I am thinking of
fitting a 42" plasma screen t.v. I recall reading on an old thread,
that I can't find, that they produce some heat. I don't intend to
mount it in an enclosure so don,t think this will be a problem. What
does concern me is its possible weight and type of fixing to the wall.
I was considering using m10 expanding type rawbolt.
It will be fixed above an unused chimney opening to old stock type
bricks.
Will the rawbolts hold it or would a resin based bolt fixing be
preferrable ?
Your thought or opinions appreciated.

Unrelated advice but I suggest you think about fixing it lower down.
Eyeline when seated is usually below 1m and it's more comfortable to
look downwards than upwards so I'd suggest you keep the top of the
screen below 1m.

You often see flat screens in design mags mounted where a picture would
be but that's because it looks good in photographs not because it's
pleasant to watch sitting down.

They aren't that heavy - nowhere near as heavy as a biggish radiator
full of water. The brackets that come with them usually allow for 3
screws per bracket. As long as you use sensible sized screds (say 60mm+
no8/10) with wall plugs it will be more than adequate.

As for he heat, yes, they do produce some heat. Maybe 400W at a guess
for a 42". But again, this isn't anywhere near as much as a radiator :-)

Anyone care to widen the discussion to include LCD screens, which are now
coming on the market in bigger sizes - 32 to 42"

I would be interested in any experience and I expect
OP dave would be too

I was thinking of putting a plasma or LCS screen over a fireplace with a
gas fire - would the heat from the fire affect the screen? There would
be a mantlepiece.

There is an inverse relationship between temperature and reliability
in all electronics so yes - it would affect the lifespan.
Additionally dust particles swept up by the rising air would adhere
to the screen.

As mentioned elsewhere, you'll get a cricked neck looking at it up
there.

Where are we going and why am I in this handbasket?

But is about the same as an aga, which heats the whole house at this
time of year...and a 30 sq meter kitchen in winter...

Surely an Aga has got to put put more than 400W.... 4kW perhaps... From
when we last built a computing lab at one of my old jobs, a PERSON puts
out about 400W... (Used for calculating how much aircon you require).

Only when excersising hard, or on fire.
400W =100 calories/sec = .1 Calories/sec * 86400 (s/day) = 8640 calories.

Not exercising very hard though... I went & got some hard figures...
400W is a bit on the high side, but not anywhere near exercising hard...

The figures from
http://web.media.mit.edu/~testarne/TR328/node1.html#tabhumanpower give
the following

sleeping 70 kCal/hr 81W
Sitting 100 116
Driving 140 163
Carpentry 230 268
Hiking 350 407
Swimming 500 698
Dist Run 900 1048
Sprinting 1400 1630

Personally I was surprised at the high figures for the sprinting... BUt
the hiking figure is almost exactly 400W (407). Considering the figures
were for people working (supposedly hard, they were students in a lab
400W per person without lighting, computers etc seems about right.

Definitely not. The maximum is about 1kW and that is after a major
cooking session. In steady state it is no more than 750W with gas or
oil models because the burner modulates.

I've measured the input gas rate and calculated the power consumption.

In rest state, a human is about 100W.

Am I missing something here. How do you cook on 1kW ?

Recently installed a 9kW total hob and I had to agree with somebody here
(Christian) that a good gas hob would still be faster.

Aga kicks out 600W according to the specs. They are VERY well insulated

Person kicks out about 100W. From memory. Average. Aircon probably takes
into account the computer and lights they are using as well..
