I'm trying to build ducting to get heat from 4 s7s out of the basement through the exhaust for the dryer and want to know if it's big enough or needs to be widened? Should the exhaust have it's own fans pulling air?
1 watt = about 3.4 btu
so 1000 watts = 3400 btu
200 watts = 680 btu
thus the s-7 is close to a 4000btu heater
the cfm is about 200 at 4000 rpm fan speed
Does all the 1000W get converted to heat? I had an HVAC guy mention to me that even though the unit takes 1000W, if the antminer is 80% efficient (for example), then only 200W is released as heat.
I'm not clear on efficiency of the power useage for the antminer, nor how much of the 1000W actually is converted into heat.
Any ideas?
