Hi Everyone

Quick intro, I have recently started house bashing due to twice being made redundant first as an auto spark and second more recently a server electrician installing power systems to servers and the likes.

Anyway, A recent call took me to someone bathroom with a ceiling fan fault. Did the usual diagnosis and found fan unit to be faulty. My question is, both the fan (240v) and the isolator are positioned that they are in zone 2. Looking at my trusted greenie it seems that this set up does not conform (if i have interpreted it correctly that is). My dilemma is do I replace fan anyway or report this as not conforming and price up accordingly to correct such.


In commercial/industrial land we always worked on the philosophy " if i don't make the existing installation any worse then go ahead (within reason of course) but, Domestic land is a whole new beast and usually is last man frees all.

any help guys and gals would be much appreciated.
 
I used to play with this:

Now THAT produces steam! ;)

water doesnt boil at 100oC
No, it boils at 100°C. The altitude doesn't necessarily make any difference, it's down to atmospheric pressure; water boils at a lower temperature onboard aircraft not because of the altitude but because of the reduced cabin pressure - if the cabin were pressurised to 'standard pressure' water would boil at 100°C at 40,000ft and you could get a decent cup of tea. At higher pressures water boils at higher temperatures, such as in a pressure cooker, regardless of altitude, although of course reducing the external pressure would reduce the maximum internal pressure possible before the safety valve operates.

I did state that it only boils at 100oC at sea level because of pressure.

if you did read the whole post you would have seen that

I didn't mention pressure initially, you brought that up and declared I was 'wrong'.
If we're being pedantic, water doesn't boil at 100oC it boils at 100°C, and as I pointed out, 'sea level' is irrelevant, it depends on the pressure.
 
and when water vapour condenses, it becomes ..... water. and it's not just internet info. i have A level physics and as part of HND did physics theory almost to degree level. steam is invisible as it's a gas, not vapour.

"The steam you see rising from a boiling kettle is actually invisible water vapour CONDENSING to form tiny water droplets as it spreads into cooler air" FACT
 
UNG
Steam is created by water vapour condensing. It does not require the water to reach 100c for steam to be produced. Steam is actually invisible water vapour condensing to form tiny water droplets as it spreads into cooler air.

I've had many showers and opened the door and steam has billowed out.

If it req. water to be at 100c then no one would need a fan in the bathroom.

pressure is determined by the elevation

Pressure at sea level or any level for that matter naturally varies although not by much with weather changes have a look at a barometer, so therefore the exact boiling point of water will vary slightly from day to day if we are really being pedantic

how can you see something that's invisible?
