Light the Brat Signal!

interesting, thought it was only Scotland that used that word

The way my Mister plays it, random shootings of members of the public as well, not necessarily fatal (although usually )

Unrelated question: Hypothetical room, radiator in the middle pumping out heat, even though it's not physically attached to anything. The radiator is surrounded by layers of insulation so you can't feel the heat of the radiator.

Question: What happens to the heat eventually? Will it all get in to the room? What happens to it if not all the heat gets in to the room?

Yes. Heat transfer for a given surface area is related to:

1. Temperature delta
2. Insulation levels

I guess some hypothetical insulation could be 100% efficient and no heat escape, meaning it's all contained within the radiator itself, but otherwise it would heat the room.

Thanks :thumbs up emoticon:

What kind of radiator?

With an electric radiator in a perfectly insulated enclosure, the heater heats up until the element melts. There's nothing to cool it down, so it doesn't.

With a gas central heating radiator, the hot water simply leaves at the same temperature it entered and the radiator stays at the water temperature. The heat emitted by a radiator is proportional to the temperature delta between the water and the air. In the insulated box, the air warms up to the water temperature and no hotter.

Why do you ask? Have you invented such a box? It could make you rich. If our houses were perfectly insulated then our own body heat would cause them to become too hot, even in freezing weather. Of course, the ventilation would also require perfect heat exchangers if we weren't to suffocate or let all the heat out.

Nope I've heard it as far South as Peterborough. Although there is some sort of big company in Huntingdon that's called Munters. Occassionally see Munters vans on the A1(M), always raises a bit of a smile.
