My set-up to heat house using bitmain S7 (UPDATE 03JAN2016)

[rockyforever]

Well done.

Maybe I didn't understand / missed this part.  How are you pushing the air around the house?  Do you keep the furnace blower set to always on?

this was an option I was using but the furnace blower was sucking the cool air from inside the house and pushing it back through and was cooling off the air blowing from the miners. The air was to cold to have blowing constantly.

The 470 cfm duct fan is sufficient to blow throughout the house. When i put a piece of paper or plastic in the vents in the rooms you can see it vibrating strongly from air flow. Also if you stand on the vents in the room they are warm to the touch from the air constantly blowing on them. The one thing that sucks now is my garage is back to being cold again lol

My house is a little over 1000 square feet. They ran the hvac system to the nearest point of each room to reduce the amount needed under the house. this allows for efficiently and less cfm to move air throughout.

If i had a bigger house (2 stories or 1500+ sq ft.) this system wouldn't work and I would have connect directly to the one rooms vent access.

Understood.  That's a solid setup (I have a single floor ranch myself that is < 1000 sqft much like you).  So this intrigues me

It would work than. I tried 2 previous in duct fans with lower cfm (180 and 350) that failed miserably. This one was more expensive but moved the amount of air needed, also if the fan of the furnace is turned on you don't have to worry about adding a dampener because the cfm is sufficient.

How much extra energy do you use to take away the heat from S7?

I think even with natural convection, the heat generated by S7 can heat a room without the complex set up.

The watts to run the in line fan is the "extra" energy used to utilize the heat generated by the S7 but this allows me not to have to turn my furnace on to heat the house.

Have you calculated how much money you save by using the S7 to heat your house?

Last month my electricity bill was 180$. That was running 2 S7s and 3 S3+ (just recently sold). First winter in this house since I bought this spring so cant compare costs but I can compare some friends houses and their bills (they were interested in comparision as well).

A friend with same sq ft paid 165$ in heating, another paid 230$ and a third paid 345$ (they have a two story though). All were shocked that I was paying near the same, cheaper or way cheaper.

Nice little setup although how effective is this heating method for your home?

Nice little setup although how effective is this heating method for your home?

working just great. keeps my house between 68-69 in 4 rooms (master bedroom, living room, kitchen and main bathroom). Its not a method but really just utilizing the heat already generated by the miners to heat the house.

[rockyforever]

just ordered another 2 S7s so I will create a custom vent duct with sheet metal so all 4 (connected with flexible ducting) will be utilized to heat the house. I will see if its the same or better.

Wow, brilliant! Ive joked many times about using mining equipment as space heaters, but this is way beyond what I envisioned! Well Done!

Would a single 6" alum flex tube attached to the fan blowing directly into another room work as well.

Indeed it did. Updated with a sound reduction box. Waiting for batch 9 to arrive to add to the set-up

Like your setup mate! I'm also heating a house with miners, if u wanna check it out here's the link: https://www.youtube.com/watch?v=mfmfdEjRkWU
I badly need to insulte the room because of noise with the S7's, would you insulate the room in the video, or create a box like you did, inside the room instead?

Do you know the amount of dB your setup makes?

Thanks

Nice set-up!

Insulating the room would be easier but prob would still be louder than enclosing the S7s with an insulated box. The box is more of a hassle having to cut ports for the air to come out and air going in but would enclose the sound to a smaller area. Either would work good. Just make sure the insulation is both fireproof and sound reduction.

I did not have a dB meter to test the difference but it is incredibly quieter! (10x quieter)

goodluck!

whatever you end up doing please take pics!

Came up with a redneck solution instead, has killed the high-pitch sound, so its not a problem anymore.
What I did was basically make sure all the miners get direct cold air from the outside, which made the temps go down. And then the fans didn't have to work as hard anymore, problem solved (for now).

Quite a good idea to be honest, I like the way you are saving money on heating and using that to run the bitcoin miner, very efficient  

I disagree that. It is not efficient simple reason that miners will not earn money back because difficult level rising all the time and when you use example 1000w keep miners running you will get only 1000w heat. If you use air source heat pump you will get 2000-6000W heat per one 1KW so it is much more efficient for heating than running miners.

So you have to spend 2-6times more electricity when using miners compared heat pump or other efficient heater to heat house for same temperature. Keep that mind when doing calculations.

I see your point, but you can't really compare the two.
Sure, if your goal is to use as little electricity as possible to heat your house, then there are more effective ways. Insulating walls, roof, windows and burning wood comes to mind.
Throw in a heat pump in the mix and you're good to go.

But, if you eitherway are going to mine, its more efficient to use the heat, instead of just pumping it out of the house.

This is how I do it:
Family and friends are heating their houses with 1000-2000W electrical heaters. So I replace their heaters with miners. I pay half the electricity.
They get: Same heat for half the electricity price.
I get: Location to host miner, half price on electricity.

This is how you ROI a miner today

I support Torepia answer on this.

The goal wasn't buying the miners to heat the house over my furnace. trust me it is far cheaper to use my gas furnace. The goal was to utilize the heat blown off the miners. Instead of blowing the heat elsewhere, I can use it to heat house.

At this stage in mining, it will take 6 months+ to get ROI mining straight bitcoin (depends on electricity cost). But most people who keep say "ROI is an issue" they refuse to mention or include the fact that reselling the miner will easily get you over your ROI. Even if you don't mine enough to get your ROI, the reselling will.

Look at prices currently on the marketplace section, ebay, craigslist, amazon, etc.

Thanks for good reply torepia and rockyforever. My first post was little bit narrow minded,sorry. I am using miners as well to heat my house. I want to be part of network and collect some acknowledge about how bitcoin works and that's why I am mining right now. Heat it just extra that I use for. I have 2 x antminer s3, 2 x antminer s5, 1 x Dragon 1THs and one bitmain.ch 600ghs. Overall 5Ths hashpower and those keep warm my whole house (100m2) and garage. Here is about -5 to -35C degrees outside so all heat coming for purpose in winter time. Antminer S5s are good for garage because those are little bit a noisy there it won't trouble and S3s are good for bedrooms because those are quiet even running overclocked. I paid about 1200e for all these and those have been mined for 500e after I got those, electricity bill is about 70-100e bigger than normally but now I keep garage plus degrees normally won't, so electricity bill is about the same now if you compare that heat for the garage what I still need. Let's see what happens after halfing that should I go to buy heat pump and keep only S5 running in the garage.

I have my S7s blowing in through my HVAC and now have 3 Avalon 4.1 I bought from Droid in my house. My house is now too hot lol, I have to open the windows now in my house even though its 35f outside

I've just switched on a 2nd hand S1 in the cheapo version of the project.
Seeing the coldest nights of the year forecast for the w/e and plenty of sun for the solar panels, A little bit of extra heat is useful to me.

Unlike the writer, who is using an efficient S7, I'm sometimes using an old S1.  The quantity of bitcoin/Watt made is 10x less; the bitcoin mining is only a by-product of using a 2nd hand miner for heating.

God that looks dangerous. Hopefully you have an extinguisher, smoke detector and insurance handy to keep your family safe.

umm why? please explain. If your referring to the insulation you didnt read or click on the links provided.
