Have Fun Staying Warm
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 is a “heat for heat” comparison. Bigger – less well insulated houses may need lots more heat.
This British Gas article says the average 3 bed house uses 12,000 kWh of gas, I use 1/3 rd of this. If you are the person using this much gas YOU are the person boiling the planet ! not the bitcoin miners.
Get insulated + Heat Ventilation Recovery ASAP & stop burning fossil fuels !

Above is my current setup updated to reflect The current Government price cap is set at 15p/kWh for gas 34p/kWh electric). My electricity from Octopus is about as cheep as you will find during off peek in the UK its for Electric Vehicle drivers only (GO tariff).

1 Year service + filter change

This is 1 "season" (winter months) of mining. If there were no filter, half of this dust would be stuck in the electronics & fans of the mine its self and could cause over heating, which is what I think caused my first mine to fail.
This is a 12" x 15" x 95mm HVAC filter. It works brilliantly with no hair or dust in the mine after a year. |

ASICs are very loud (80-90db) so they need ideally to be in a sound proof box. Venting the warm air into an adjacent room is the best way to circulate it around the house or business. 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. Leave it on 48hr to see how warm the house gets you will probably find 3.1kW of the Bitmain S19j too much heat. Unfortunately they cant be turned down but can be switched off.
When its too warm to mine 24/7, I like to operate 7:00pm in the evening to the morning, taking advantage of cheap night time rate electricity. |
Room Air Flow

Bitcoin mine in a sound proof box

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 Diameter. To allow the duct to fit in without having to squash it in. A noise reducing duct could be placed on the inlet as well & will reduce noise by a fairly unnoticeable 1 or 2Db. Vent Sizes Cross Sectional Area (CSA) The largest Vent on the T15 measures 7" x 4.5" = 31.5" Power supply vent = 2" x 1.5" = 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 latest Bitmain ASICs are bigger (400*195*290) than they used to be & I find they will no longer fit this size box ! 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 ( If you can bear the noise 🤪) in a cool area for a couple of hours. They can take a while to start especially the first time on your pool or if they been stood along time.
Bitmain S17 web portal
A cool - well ventilated mine is a happy mine. The fans have to work slightly harder in a box, self adjusting to 2700-4500 RPM as opposed to running slower when free standing. Chip temperatures are less than 80c. Is this good or not I don't know as Bitmain do not specify a max temperature, but that is the temperature I like to stay below. The fans will increase if its tohot.

Air intake moved from the top to the side so its sucking the coolest air from lowest point. 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 shown 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.

Asthma It also has the added benefit of continuously cleaning the air. I have a mild dust allergy that occasionally causes asthma symptoms, this seems to have gone away since using this heating method.

I do not recommend this method for high flow rate mines such as S19 S17
The S9 range has a lower flow rate so may be ok. 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.

A good artical on noise cancleing.
https://www.fhwa.dot.gov/ENVIRonment/noise/noise_compatible_planning/federal_approach/audible_landscape/al04.cfm HeatbitSome companies are starting to make free standing heaters that actually mine bitcoin.
At 93 Watts/THash these Heatbit room heaters are only 1/4 as efficient as say the latest Bitmain S9 pro XP - 20.8 W/THs
