Saw this ad this morning and curious to know the community’s thoughts/or experiences with Heatbit, it appears to be a relatively new company that’s a heater and bitcoin miner (up to 39 TH). Is anyone familiar?

I want to switch from 1 mining pool to another how do i do it?

This setup has a 4 S19 unit tank(built in-house) which has been installed in place of the former pool heater. We use BitCool for the oil. The oil meets the water through a heat exchanger under the immersion tank. Pool stays around 85 degrees. This system has been running for over 18 months without any hiccups.

I've had a heatbit for 6 months or so and got a lot of learnings I want to share to help Heatbit and others.

Pros

• I pay to use a heater normally, would much rather earn some btc at the same time

• This is very helpful with Solar panels. Free bitcoin and love that it helps the network while keeping me toasty + making mining green.

• If helping to heat your house/office/school, this is a brilliant win/win for the network and owners.

• Relatively quiet for a miner

• Reusing old miner chips that would normally be landfill due to being inefficient. (Would prefer an updated one with faster chips but meh)

• Reduces centralisation (Could do more with running node as below)

• Form factor is beautiful, people don't realise it's a bitcoin miner

Cons

• Earned around $40 so far, cost was close to $1000 so will unlikely ever pay for itself

• Whilst quiet, it's far from silent, i.e. it is too loud to have on in my office when doing calls. Could probably be quieter as it's the airflow through the vents that causes the noise, not the fan. Placing a bag on top of the machine to reduce vibrations helps slightly. Pointing the vents away also makes it quieter.

• Stability. I think this is historical now but there have been many weeks without mining waiting on support to help get the thing back up and running. Typically happens when Wifi PW changed and resetting is non-trivial due to software bug in app (infinite scrolling) and difficulty in understanding the state the machine is in. (Is it on, off, booting, closing down, crashed, bricked?).

• The single button on the front is over utilised and needs attention. This is a software issue so should be easily fixed but actually my biggest gripe because it detracts from what this should be... a simply miner to warm my home/office.

Suggestions

Add a full bitcoin node capability to the system? Perhaps ask customer to add 2Gb SD card for full node?

Run a lightning node for people to connect their wallet to inside the Heatbit.

Send the heatbit earnings to the Lightning node rather than a blockchain address (PM if you need a solution for this as my company can help)

Add ability to 'smooth' the airflow out to make it quieter.

Add a small bitcoin symbol + version number on the exterior somewhere (A sticker would do) for some self promotion that it is bitcoin a miner running say 7TH/2Kw.

Power light + Button design.

Current setup for the front button is

When On

1 second touch - turn it on OR switch heating modes via the app.

5 second touch - turn it off

10 second touch - Enable app to control settings (like set the desired room temp)

20 second touch - factory reset

When Off

1 second touch - 30 second delay. Turn on. (Light comes on after 30 seconds). This is insanity, it looks like it's broken when first arriving as pushing the button has no immediate feedback.

Light on/off/flashing: I have no idea what these light states mean. I've seen the light on and machine off, the machine off and light on. Flashing when both on and off. It's random, misbehaves due to bugs or is so cryptic it may as well not have a light on it. My hunch is it's bugs and OS latency that causes it to be confusing.

These need printing on the device as a label or in the app somewhere as I couldn't find this documented anywhere apart from support.

I'd suggest change the button to be just ON/OFF. Here are the details of the sugestion.

When device is powered on but OFF (or first plugged into power).

H button should be OFF. (0% brightness). The computer should be up and running, just not mining. If I wanted to fully turn it off, use the OFF switch at the bottom. If it's plugged in, I want this thing running 24/7. If it's not mining, just turn the fan off.

Press push button once to turn on. As soon as pressed, change the light to 100% brightness and stay on. This shows it's booting up. Once it's ready to mine, it just starts mining away. Light should remain at 100%.

When device is ON and mining:

The H button should be on 100%.

Pressing the button once to turn off.

The H should flash as it starts powering down. The computer should stay on, but miner stops.

When mining powered down the H light should turn off.

Reset Machine/Wifi:

Press and hold H button for 10 seconds.

H now flashes on/off at 2Hz. The Heatbit wifi appears and can now re-add the machine to the app.

Make the App control ON/OFF of the device if plugged in. Since the computer is always on when plugged in (and base switch is in the ON position), there is no need to press the button on the machine to change stats. Instead use push notification when a setting changes, this way the user knows the setting worked.

I.e. keep Heatbit super super simple.

If heatbit can change their software to simplify this it would be immensely helpful. If you could offer a full node/lightning capability I'd be recommending this to everyone

Saw this video, and seems to make sense, but I’m no expert

Looking into the Heatbit heater, supposedly it mines bitcoin and simultaneously heats your home.

Does anyone have one? Is it worth it?

I live in Canada, thx

I am redesigning my garden and will add a pool. I also own a mining facility (not at my home) and thought why not use mining heat to warm up my pool..

I thought about a underground room (like a pool tech room) where i keep some asics with in-air vents and out air directly into the pool, simmilar to the bath-tub image i attached.

Does anybody have experience with this ?

The goal would be to heat up quickly in spring and/or keep it warm in winter (i live in europe, so winter is -10 to 5 degree celsius).
And it should be cheaper than heating it with other tech...
