I'm sure it depends on how much laundry he is doing - his dryer is probably heated entirely by servers.

He can then exhaust the remaining server heat through the dryer vent stack.

Keep going. I love dry humor.

Its dryer sheets soften the soul.

Untill the exhaust starts "Feeling leaky" I guess.

Might not even need a dryer :-)

Change it to a sauna?

I thought of this a whole ago when I was a Datacentre monkey. In the winter it was pleasant to walk down the hot aisles.

However the exhausted hot air never had the same feel of a sauna. It left the air stale and dry.
