Using my mining gear to heat cold rooms in my house??

So I am coming to terms with the fact that ROI may never happen on the 6 BFL Jalapenos I just got. Feel free to ridicule me as you see fit, I ordered them after major surgery and I was pumped full of pain meds and not thinking clearly.

I also have a GPU mining rig with 3 HD 7950s.

So my question is, should I just run these things to heat a few rooms in my house that are at the end of my radiator system's circulation (and as such are always a bit colder that the rest of the house)?

I know the GPU rig kicks off a bunch of heat. And I have two room s that would really benefit so I am thinking of splitting those up to heat 2 rooms.

Do the jalapenos kick of some heat too? That would oddly carry a decent amount of value to me fm now until about March.

As of right now if I sell them I maybe get 250 each which is a loss, oh well, I could just eat the loss and move on. Or I could mine a few of them even if ROI takes forever, in hopes that one day bitcoin goes thru the roof (US Bailouts lets say or something similar or just a long enough timeline where more people get hip to BTC...) and in the meantime keep my office and my daughters room warm for the winter.

Thoughts?

I found this while digging around. If anyone wants to check my math or knows more about heat output please let me know what you think.

"for BTU calculations just use the 60W number for the device x the number of devices. x 3.412142 BTU/hr per watt."

gpu rig pulls around 400 watts x 3.412142= 1360 ish BTU/hr

jalapenos at 43watts (so I've read)
x 3.412142… should then pull 146 btus/hr

so could basically have a 1500-2000 btu heater that who knows, MAYBE, in a long long time if bitcoin prices go the the moon might make me some of my money back. The GPU rig kicked off a LOT of heat when I had it running in that room but I didn't have it running in there in cold winter months so it is hard to say if it will get the job done. Oddly the mining gear seems to be reasonably efficient for heating (if my calculations are correct)

for comparison, the amish heater that is enough for that room (which I think is 1300ish cubic fi

1500 watts, or 5110 BTU

which I would be running anyway but it doesn't mine bitcoin!!

If they sell they sell, if not I'm going to see if they can help me keep that room warmer.
