I have a computer in a room that’s generally otherwise too cold… so all that power is just useful heat dumped into the room.

- londons_explore 5y agoIf you pay a lot for electricity, you could get heat cheaper with a heat pump, gas furnace, or simply adding insulation on the roof/walls so any heat you do add lasts longer.
- varjag 5y agoRe-insulating a house is a substantial cost that can take a decade to pay back in utility bills.
- londons_explore 5y agoYet spending $6 on draught excluders to keep the wind out can pay back in just a day or two. It all depends on your baseline...
- midasuni 5y agoAlbeit not as efficient as say a heat pump
- deadbunny 5y agoSignificantly cheaper though.
- yjftsjthsd-h 5y agoCheaper to buy, but not to run
- easygenes 5y agoCommodity window-mount heat pumps which run off household power outlets can be had for a few hundred dollars, and are good for a minimum of a couple kilowatts of heat output. Any computing solution which dumps a couple kilowatts of heat and didn’t fall off a truck would probably cost more than that. Computers are fairly efficient heaters, but they’re a lot more expensive than heaters.
- NorwegianDude 5y agoThat depends. The heat might be used in a heat pump for all we know.
- easygenes 5y agoWell given that all but a tiny percentage of the energy consumed that’s not waste heat is either going into useful computing or keeping fans spinning (which you would have in any sort of HVAC solution), I’d say it’s super efficient.
