What do you think? Thank you in advance for all replies.

I would consider a heat lamp to be a fire hazard and to pose a danger of
shrinking/warping/melting synthetic fiber carpet. Carpet backing is
often, I believe, natural fiber and subject to shrinkage.

Are you addressing shampooed carpet or disaster? When carpet is wet,
use a shop vac to remove as much water as possible.....for disaster,
where the padding is saturated, rent a heavy duty vac with squeegee
nozzle. Then run AC or heat to get air dry and run fans in room with
wet carpet.
