Or I'm sure if you gave us the dimensions and some idea of what each
surface is made of someone would be able to help.


I doubt that, but lets just imagine a very simple room, about the size of my office.

3.5M X 5.5m and 3 metres in hieght.

Ok, that's a start, but ...

1) the size of the lab might be more relevant if we are wasting our
time on you.

I'm keeping it simple for you

How kind. ;-)

After talking to my studetns yesterday I now understand that I need to make things much clearer, so nwo you're getting multi-choice questions just lioke we do here when things get complicated.



as there are 3 labs,

Are they one airspace or separated. If the latter we only need the
information from one (as a starter).

No idea what do you mean by airspace seprated.
Where the flats in grenfell tower airspace or separated.

I have posted videos of the lab how comes you can't work it out from those.



and my office was teh only place I tested the heaters.

That's of no use re calculating the heat loss from the labs. IDGAF how
cold you are.

Yes I know, so how do the professionals calculate what to use or how to heat an aera. ?

A professional is someone that is paid to make these calculations and can understand both theory and practice.


2) A clue as to the size of any windows and the construction of all
the (especially external) surfaces.

Large triple glazed windows

'Large' as in your mouth or ego or something different? ;-)

Large as in the inverse square of your brain capacity.



that haven't been completely installed.

Ah, so, are we talking wind tunnel / tent then?

No, there are no wind tunnnels in this lab, the lab where there are wind tunnels in the aero lab and this is NOT a place where they test areo chocolate bars.

That's the lab just outside where they are replacing the roof and building an extra floor.

you can see some of the building work from outside.


see the small blue 'door' on the right that is the entrance that takes you to the labs, that blue section no longer exists as this is the doorway students use to go up to the 2nd floor where they enter the lab.



Or calculate it as from 3 weeks ago when we had NO windows.

I'm pretty sure your power supply wouldn't be up to that.

We do not have a power supply for that, we never had.
The heatting was suplied from a differtn building NOT in this building.

What sort of power supply would you suggest as the requirement for running labs in that the temperture should be a minuim of 16C as stated in the factories act of 1992 section 7.

How many 2KW heaters would be needed ?
or would you prefer to quote for 1300W heaters ?

Q1
If it was caluclated that you'd need 20 2KW heaters to heat a lab to the required temperature and replaced them with 1300W heaters would you need .

A More 1300W heaters than 20
B exaclty the same number of heaters
C Less 1300W heaters
D We have no idea because we don't know if they are one airspace or separated




You have been given lists of the sorts of materials and their u values
so you could help yourself a bit.

Get it through you're thick skull I am not gas registared so can't do those things.

Where TF have I said or suggested you have to deal with the *heating*
(especially gas). All you are supposed to be doing so far is working
out the heat loss.

that was the link that was posted, did you not check that link ?
