Unless you have the latest ASIC (Application Specific Integrated Circuit) mining hardware don't bother. If fact just don't bother full stop !!
Anything you buy costs lots of money and may go out of date in 1 year. With the price of Bitcoin at less than $4000 It would be a much better investment to just buy Bitcoin.
The noise from these ASICs is horrific, really, 90Db and it never stops! it will damage your hearing and make you very unpopular with the family and neighbours and generally burn as much electricity as it will make in Bitcoin.
However, if you're not going to listen and you want a heater that makes money or a Bitcoin mine that heats your home, you've come to the right place.

This heater cost money :-(

What you need to Mine Bitcoin-
- Electricity.
- An internet connection.
- A Mining Pool Membership such as www.slushpool.com (A good one for beginers).
- An ASIC mining rig. Cost $1000 - $3500

Venting the warm air into another room is the best way to circulate it around the house. There is such a large air flow that you may need to cut 2 holes in the adjoining walls (one in and one out) or make sure doors are propped open. I find the T15 on low power mode 20THs / 1200Watts keeps the whole house warm enough down to -5c. The house is well insulated for an old house. You could experiment with a regular heater to see what wattage you need.
Assuming BTC = £6500, Running it 24/7 generates £37 in BTC / week and uses about £34 in juice. I tend to run it just at night on cheap rate electricity so its more profitable.
As my electricity is 100% renewables its also Zero CO2 - green as a green thing.

This method reduces the noise level of 1 mine down to 50 Db @ 1M. It cuts out all the high frequencies leaving you with a low rumble, like a tumble drier which can only just be heard in the next room.
These things REALY need to breath, so reducing the air flow must be kept to an absolute minimum. The air intake best placed on the side or bottom where the air is coolest. The in and outlets needs to be about 8.25* or 210mm. To allow the duct to fit in without having to squash it in. A duct may not be required on the inlet. Vent Sizes Cross Sectional Area The largest Vent on the T15 measures 7" x 4.5" CSA = 31.5" Power supply vent = 2" x 1.5" CSA = 3" Total CSA = 34.5" So all paths through the enclosure must not be <= 34.5" CSA and preferably much bigger. Duct CSA = Area of a circle A = π r ²
10" =3.14 x 5² = 78.54" Longer runs 8" = 3.14 x 4² = 50.26" OK for short < 5M 6" = 3.14 x 3² = 28.27" is less than the CSA of the mine therefore will restrict air flow and kill your mine. Materials Required-
Tools Required-
Box overall dimensions L = 970mm, H = 520mm, W = 582mm Wall thickness 45mm (2 x 22mm + sealant) The mine is placed in a partition lined with Sound proofed insulation so as to avoid direct contact with the inner box.
The partition is placed inside the similarly lined outer box and thus double acoustic isolation is achieved. Decide where your duct entry and exit are going to be so you can work out where the inner box vents will be. The air intake should be at the bottom so as to suck in cooler air from low down. Inner partitions are not glued just held in place by the second layer of insulation.
The feet designed to stop vibration being transmitted through to the floor. You may want to use trolley wheels and or lifting handles as the finished box is very heavy. Ac50 Sealant is in a much bigger tube than regular sealants 900ml. So rather than pay £16 for a large sealant gun I'd never use again, I used LEGO! and elastic bands.
The main box is double thickness screwed and glued with the AC50. The lid just rests on the draft excluder and latches are added.
Drill a hole just big enough to thread the Ethernet lead through, then take the plug off the mains lead thread that through the same hole and put the plug back on. Make sure there is enough cable to get to the mines connectors then seal the hole with AC50. In this example the air flow changes direction by 90degrees 5 times ensuring all noise has to do the same diminishing every turn.
Running mine for the first time. Run your mine free standing in a cool area for a couple of hours
The fans have to work slightly harder in a box, self adjusting to 4680 RPM as opposed to 4200 free standing. Chip temperatures are less than 70c. Wether that is good or not I don't know as Bitmain do not specify a max temp but that is the temperature I like to stay below.

Air intake moved to the side. Seems happier!
I find if swapped the hard board surround for insulation, less sound is transmitted to the outside.
A insulation lid is placed over this centre section, then the whole thing has one final layer of insulation. Generally 2 layers of insulation where ever possible. Be careful not to insulate the mine, don't want it getting too hot.
Draft excluder show above is added to the center boards to make a better air seal, then also added to the top edge (not shown) before placing the lid on.

I don't recommend this method.
I just included it for comparison, but its quick and dirty ! The fans are working harder 5280-5400RPM and the chips don't run as cool (70-80c) + its still quite noisy down 60 Db (still annoying). It cuts out all the high frequencies leaving you with a low rumble, like a tumble drier which can still be heard in the next room. These things REALY need to breath, so reducing the air flow must be kept to an absolute minimum. The air intake is at the bottom where the fridge motor would normally be. The outlet needs to be at least 6" or 150mm. Preferably 8*. 4" does not work as there is not nearly enough air flow. The largest Vent on the ASIC on the T15 measures 7" x 4.5" = Cross Sectional Area of about 31.5" + the CSA of the power supply about 2"x1.5"= 3" 31.5 + 3= Total CSA of 34.5" So all paths through the enclosure must not be < 34.5" CSA and preferably bigger. Duct CSA = Area of a circle A = π r ² 10" =3.14 x 4² = 78.54" 8" = 3.14 x 4² = 50.26" 6" = 3.14 x 3² = 28.27" is less than the CSA of the mine therefore will restrict air flow. Materials:-
1 roll of weed suppressant. 1 roll of Masking tape. 1 pack of Wickes Noise and thermal insulation 1200 x 600 x 30mm. 1 old fridge thats has been left out for the scrappers. 8" duct optional. For long runs use bigger duct or fry those ASICs. Method.
