depends on you heating cost.. if you get heat cheap enough with your normal HVAC system you still lose money heating with old tech ASICs and/or GPUs.. just not as much. loss is loss.
I would lose money big time heating with my GPU and 65 nm ASIC stuff vs my geothermal HVAC.

You're really not mining a coin? I'd at least mine some scrypt/x11 etc coin. What type of artificial load are you giving your GPU's?
It wasn't Winter when I wrote I'm not mining anything because it's not Winter, and it still isn't Winter, so none of them are running. 
With propane prices, though, I think I'm going to wind up heating the house like a normal person this year... I'll let them run on a Scrypt multi-pool for a week and see if it's worth it.

If anyone on propane was considering this, it might be worth checking propane prices again in your area, esp. if you're in the US. Propane prices have collapsed. Futures contracts seem to be pointing toward continued freefall in retail price into Winter. For those who stock up on propane before Winter for a better price, it might be worth trying to wait until it actually is Winter this year, though relative to Summer prices, current prices are pretty damn good.

Also as winter comes to the north, southern hemisphere like Venezuela with cheap power goes to summer - so minimal season effect.

Now this is a big point. the entire network is 236ph give or take a few ph
https://bitcoinwisdom.com/bitcoin/difficulty
Bitcoin Difficulty: 29,829,733,124
Estimated Next Difficulty: 33,192,651,006 (+11.27%)
Adjust time: After 1574 Blocks, About 10.1 days
Hashrate(?): 236,199,455 GH/s
now what does that number mean?
simple at 1 watt per gh the entire network is burning 236,200 kwatts or 236 mega watts.
that is not that much power
look at this puppy
http://www.power-technology.com/projects/gurihydroelectric/
10,200 mega watts or more power then 43 current btc networks. what do they charge for power?
the official rate is 3.1 cents
http://en.wikipedia.org/wiki/Electricity_pricing
so they could run the entire btc network at 3 cents a kwatt. There are more then 14 countries on the wiki list with power under 5 cents.
so at 3.1 cents per kwatt an s-1 under volted and down clocked
is cheaper to run then a 10 cent per kwatt sp30 . Since the sp30 does around .6 watts a gh and the downclocked under volted s-1 does 1.3 watts a gh. I could argue a large builder of chips/machines could have 2 plants 1 north hemi 1 south hemi as long as he can get 3 cent power. he can keep one turned off when it is hot.

exelent calculations, so this means you have found a very good way to earn out of mining, which miners do you use ?
GPUs :pI would not at all be surprised to see the difficulty increase as a faster pace this winter as people start to use their ASICs that are no longer energy efficient enough to mine more BTC then they cost in electricity again to help heat their home.
That might be true if the older machines had some relevance. I replaced 5 BFL Singles doing 300GH/s and pulling 1500 Watts with just 1 Antminer S3 doing 450GH/S with just 350Watts.
Even if every Avalon, BFL, AM Blade and block eruptor came back online it would be less than 10PH/s.
Also as winter comes to the north, southern hemisphere like Venezuela with cheap power goes to summer - so minimal season effect.

Somebody needs to invent a thermostat for bitcoin miners so that they kick in once the temperatures drop too low.
Any thermostat which uploads over WiFi should be able to do this pretty easily. Alternately, one could be rigged up for far, far less... but this is outside my knowledge area (like 99.99% of everything ).It may be possible to set up a script where if GPU temperature is

cant wait to feel the heat of my asics in a positive way

104F degrees out here in LA today. I really envy you guys getting a bit of cool weather. I can't even go out for a walk with kids let alone think about miners 
it is 11:30 am and 64 f. my miners in the garage are doing 5% better hash due to the cooler air.
I use nat gas to heat my NJ home. I will lower my heating bills about 100 usd a month using my miners.
My mining will be about 2500 watts this winter. this is 60 kwatts a day cost is 60 x .15 or 9 dollars x 30 days = 270 power bill for the miners round it to 300 a month take away the 100 in the winter and my mining power is 200 a month.
So my 15 cents a kwatt is really 10 cents a kwatt for the winter. Not too shabby.

I like hot weather, but it is getting colder here already

Haha, good idea. so you treat your GPU as a heater now? heh..
