I've seen a couple of posts by members who are using their mining rigs to generate heating for their homes. Also, I found a company that is selling a room heater with a couple of processors to mine ETH. Is this something that will gain popularity? If home room heaters can be used for mining, it will help to decentralise mining in the future.
Our ETH mining rigs on liquid cooling can be very effectively used for room heating. The minimal level of noise of 30 DBa (which is a bit louder than a whisper, quiter than a regular conversation and almost the same noise level as your fridge) makes it a perfect room "companion".
And it will keep the temperature high enough to save some energy on heating bills, but not enough to make you turn on the air conditioner.
Comino N1 is enough to keep a 25-30 square meter room comfortably warm.
Our Grando - industrial device, is built to create less excess energy and to recycle it back for heating. Liquid cooling helps recuperate the heat from the device, transport it and use it effectively in any other facility. But you would not need that much to heat you room )))
