This is an interesting topic—Iceland is taking on this challenge, in a way.

Question: Aside from heating homes and offices, are there other uses that server farm heat could be put to?

Cool idea!
Servers, especially the kind that output significant heat, are high value property. How would you suggest that the liability and security of the machines be addressed when placed in someone’s home?

I definitely like the idea of harnessing the unused heat in server farms, and agree that this would be more appropriate in cooler climates. I could forsee some downsides to the distributed system such as it being more challenging (and requiring more driving) to maintain and fix the servers when they’re in various locations. Do you have any ideas for solutions to such challenges?

This is an interesting idea.
I’m trying to get a picture of how it would work. Do you know how many servers it would take to heat a typical house and how much space they would take up? Where do you recommend I locate my server/heaters?
Do servers need to be maintained at a cool temperature to run well? If so, what are the challenges involved in transferring heat away from the server and to my living room?

This is a very interesting idea, and it seems like a win-win situation for both the homeowner and the server owner. Would there be any way to control the heat output, if the homeowner/business were to want a cooler or warmer temperature throughout the building?

So this is a good idea, but it’s also one that seems to be in operation already in some places, with news articles about it. What makes your version innovative?
