    yeah, that is nothing new, friend uses heat from small datacenter (i don’t think that 20 racks constitutes datacenter, but i am not sure if there is better word 😀) he has in a basement of that building to contribute to its heating.

    i really mean if you could make bitcoin coffee-maker and if it could eventually pay for the price difference between normal and bitcoin one and how much coffee would you have to drink to make that work.

      It’s doable, but you’ll need at least four heat pumps in series. Each one would bump up the temperature of the water, until you get 165 °C steam. The last few steps aren’t very efficient, but it’s still cheaper than using electrical heaters. Those heat pumps will take a fair bit of space and money. Oh, and those machines make as much noise as a big freezer. Other than that, it should be fine.
