[ILUG-Social] heating systems for houses...

[Smith, Graham - Computing Technician]

Well heat rises in air so the warm air underneath
would try and escape upwards into the room which
would probably work I guess. Probably very slowly
as hot air wont conduct into a solid sunstance very
well.

I cant see how it could be worse overall though...
if heat travels equally in all directions (in other
substances besides air), wouldnt you assume a lot (50%)
of heat would be lost downwards into the ground? 

I dunno i'm probably talking crap, but it seems logical
enough....  My main point is that i thought that wood
would conduct heat faster than concrete - more suited
to buildings occupied at less well defined times. 

Altenativly I think scsi hard disks and overclocked cpu's 
probably provide pretty good heating also :)

? Wouldn't it work really badly with wooden floors as
the air would heat underneath which couldn't move to
the rest of the room (air is a very good insulator
without convection)
