A completely new way to heat your house !
Imagine an expensive hair dryer that just happens to make money !
ASIC's blow out lots of warm air, why not use it to heat your house?
Power it with 100% renewable electricity and you have zero emissions heating.
Once set up its just a matter of flicking a switch or setting a timer to turn it on.
Then eventually selling (or not) the resulting Bitcoin to pay for the electricity.

This heater makes Bitcoin :-) Bitcoin pays for the electricity. Medium Install costs £1700 (£1200 for ASIC + Box £500). Can be powered by 100% renewable energy. Can heat most of house if well insulated. Can be added too for more heat. No radiators pipes Filters dust from the air / good air quality. Low quantity of materials required. Relatively Easy installation. Con's No Hot Water. Noisy - Requires a sound proof box. High energy costs / kWh £0.05 - £0.17 mostly offset by Bitcoin reward depending on BTC price. May need replacing every 3 years as tech advances. Holes in walls may be required. Run ideally 24/7 (can be timed may lose some reward) 10 YEAR COSTS Hardware Bitcoin ASIC miner £1250 x 3yr =£3750 (replaced every 3 years) Box, duct, installation $750 =$4500 Fuel 45000 kWh @ 12p/kWh = £540pa £540 x 10yr = £5400 Rewards Purely used as a heater Bitcoin £500pa x10yr = £5000 Savings Gas standing charge £120pa = £1200 Total £3700 Hot Water 10 years hot water on Economy 7 3kw x 1h x 365 = 1095kWh pa 0.05p x 10yr = £547 Ten year heat and water cost £4247 |

ASICs very loud so they need to be in a sound proof box.
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. One Year On Case Study Used purely as a heater during the winter 4 month period only. BTC Generated = 0.07 Sold @ $10,000 or £7700 £7700 x 0.07 = £540 Cost of Electricity £580 1 year heating cost £40 As my electricity is 100% renewables its also Zero CO2 - green as a green thing. |
Room Air Flow

|
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). Noise level is about 60 Db (still annoying). When the T17 ASIC is "happy" the fans will run 3700 - 5200 RPM and chip temperature about 55-68c. These figures will vary for different Make and Models. 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.
