A space heater is very efficient in producing heat.
An asic miner is pretty efficient in producing heat, the amount that is not used in heating is used to gain bitcoin.
So it is better if you need permanent heating.
You could say, well some miners are more efficient than others.
But more efficient miners are just spending more energy on the usefull calculations, the calculations themselves are equally efficient since it is the same algorithm.
wrong. watts is watts is watts.
heat from 1 watt spent = 3.42 btu of heat
so a 1000 watt space heater = 3420 btu
a 1000 watt miner = 3420 btu
If you go with some of the old miners like the old dragons they practically spit out heat. The advantage I think a true heater has is sound, they can be more quiet then most of the stuff that is being sold as "heaters".
I think it's a little of a gimmick some sellers are using to unload some almost obsolete gear. Yes they will make heat, but better hope it's one long winter if you are spending much for them.
s-3's and sp20's give plenty of heat.
I burn 1200 + 1200+ 1200 + 720 + 350 + 480 = 5150 watts as I type.
this is 3.42 x 5150 = 17613 btus of heat .
I get 7.7th of hash that is about 1100 usd a month
the heat is 4.22 therms a day. a therm is 100000 btus so 17,600 x 24 = 422400 btus a day or 4.22 therms .
4.22 therms of gas heat cost me about 5 bucks so the heat from my miners is worth 5 x 30 = 150 a month.
so I earn 1250 a month .
the power will cost me 16.25 a day so 30 x 16.25 = 487.50
so 1250- 500 = 750 profit a month due to mining.
S-3's are a great space heater. Just down clock them to freq 150.
they use 240 watts run 300gh and are very very quiet. you can run 5 of them on 1 evga 1300 g2 1200 watts 1500 gh quiet and the heat is better then free you get paid for it.
