While standard computers won’t be able to keep you nice and toasty on a particularly cold day, what happens when you take something far larger – such as server racks? Perhaps these servers could be used to power your huge business’ back end, while keeping the office warm at the same time, but chances are far higher that a custom heating solution in the form of the standard heater would be used instead.
One thing though – folks working at server farms might want to suggest to the management that during winter, they might want to find a way to channel all of that heat to the rest of the building in order to take advantage of the situation.
