So, it's a bit chilly in our office this fine morn.

The heating engineer's just been round with his snazzy laser-pointer-thermometer thingy, to reassure us that we're all not actually freezing, and in the process, explained the philosophy of the heating installation we're enjoying.

And it goes like this: the panel radiators around the walls, which have just been fitted with thermostatic valves, run off recovered heat from the air-conditioning system. This is considered a supplementary system to the panel-heaters.

What panel heaters, we wondered, in a state of collective perplexity.

The ceiling mounted ones, came the answer.

Huh. OK - that'd be the ceiling mounted panel heaters that we can't see because of the polystyrene-tile-based floating ceiling that we have, then? Thought as much...

Aside from the fact that hot air isn't well known for falling downward, there's also the slightly odd design decision of then placing an insulating barrier of polystyrene betwixt what little gravity afflicted thermal action might be headed our way and us poor code monkeys.

And all this topped off by a radiator system running off the recovered heat from the air-conditioning, such that when the air conditioning is working hard, the radiators are warm (positive feedback loops FTW!), and when the air-conditioning isn't running, said beasties are stone-cold.
