Just ran my idea to capture excess solar PV during the summer to heat water with a miner idea by a heating engineer. He was a bit of a grumpy bastard but his conclusion was "could work"... I'll take that

Yup, that was my mistake last cycle. Seemed like a great idea, ended up losing sats, not many but would have been better off DCAing.

Swapped out the s9 in my ventilation system for a NerdQAxe Hydro rev 6. Pretty simple swap, just used the same duct adapters from the s9 either side of the radiator.
Now getting the same heat input but over 5x the hash rate

I'm currently vibe coding a Home Assistant automation to predict solar PV production for tomorrow based on weather forecasts in order to do smart battery charging i.e. when it looks sunny tomorrow, leave spare capacity in the battery to prevent excessive export.
It's funny the lengths you have to go to when you have the most expensive electricity in the world, mad solar systems don't already do this too. Thanks NetZero!

Not that I’m looking for approval or praise. Just thought if heating with mining would interest anybody it would be here.

The disconnect between the "you can just do stuff" vibes on nostr and the actual engagement you get when you do actually do stuff is quite amusing. Kind of the same as real life, people say "yeah, doing stuff is great" but when you actually do stuff they don't care or are pissed because you're highlighting the fact that they don't do stuff.
Conclusion: cat pics > doing stuff.

Right, nerdaxeq++ rev6 hydro purchased. Hopefully that sorts out the foibles of the DIY PIV unit making it quieter, a bit less sketchy and way more efficient hash rate wise.
Here’s a diagram of how PIV works, I’m just using a miner as the heating element instead of an off the shelf unit that uses a ceramic heater… the idea is to increase ventilation and reduce humidity/damp/mould in my old stone walled house.

GM, been running my miner PIV system for a week now. It’s working well, definitely pushing lower humidity air into the house and making it feel fresher. Whether it fixes the pesky damp patches on the exterior stone walls remains to be seen.
The issues I need to fix with it are noise level and efficiency. It’s not gonna be cheap, the best way I can think of is to replace the S9 with 2x NerdQAxe Hydros so I match the current 200w heating output. That should sort the noise and j/th efficiency out.

Got my miner PIV system installed today. Currently in MVP test mode with it but getting good results so far. Output is 20C at 35% humidity with the S9 running at 270w. Only bummer is how terrible the s9 efficiency is, still better than using electric to heat for no sats at all!

Testing out the loft PIV system. Good results so far, miner running at 250w, getting a +8C temp boost.
Next step is fitting it all together in the loft.
(New carpet is lots of steps away sadly)

A belated Happy New Year nostr! I’m starting off the year with a heat punk experiment, attempting a DIY positive input ventilation system with an S9 for heating.
If you haven’t heard of PIV systems before, it’s basically a fan blowing air from the loft into the house creating positive pressure. In theory this helps reduce damp issues in old houses by reversing drafts and reducing humidity.
The water heating project with the S19 is on the back burner while I find a heating engineer

Been thinking about making a miner positive input ventilation system. My house is an old Welsh farmhouse which costs a fortune to heat and is still damp and cold. Anybody had any experience with PIVs? Do they actually work or just add to your heating/leccy bill?

The radiator works now though so success! Still need a plumber though, don’t think a YouTube tutorial will teach me to service the boiler

2025-12-06 12:46:46 UTC

YouTube how to videos never show you the bit where you undo the radiator valve and dirty water pisses up the wall. Managed to get the valve changed tho, hopefully that fixes the cold rad.
Plumber was supposed to turn up today but in the Socialist Republic of Britain nothing works as it should.

The plan is to convert an s19 to water cooling and run it through a buffer tank heat exchanger coil which will be connected to the central heating/hot water.
Had solar pv fitted and because of our system they couldn’t add a switch to dump excess into the hot water tank.
So the miner will (hopefully!!) heat the buffer tank to add some kWs to the system and save on the gas bill whilst earning sats. We also have a cheap night rate so hoping that will be profitable but it’s slim margins.

It’s amazing how lucky we are in the UK, you can pay £15k for solar pv and a battery and you’ll be privileged enough to pay the same for electricity as you did all those years ago in 2021

gm, has anybody bought anything from Zeus Mining (zeusbtc.com)? I need to get an S19 hydro conversion kit for my heating system project #asknostr #heatpunks

2025-11-26 20:04:37 UTC

- reply

That's a cool product! I've got a used S19 on the way so was a bit worried about dropping it into oil so planning on using a hydro conversion kit instead.
We just had solar PV fitted with a battery but the heating system uses a gas combi for radiators and the HW tank so we can't easily dump excess solar into the HW tank. Not sure how much that would save anyway if there's little demand at peak solar.
I figured that a buffer tank is just an extra battery but way cheaper than an electric one. So hopefully we can run the miner when we're getting excess solar and use the cheap rate at night to "charge" the buffer tank. When there's demand for heating/HW the buffer tank can help the combi and save on gas.
Thanks for the link, there's a rabbit hole for me to go down on SN!

Nice! You’ve got an immersion system? I’m planning to do a hydro conversion on an s19 and use a brazed plate heat exchanger to feed a thermal storage tank that then adds heat to the hot water and heating.

2025-11-25 11:41:40 UTC

It’s funny how similar heat pump systems are to adding a bitcoin miner to your heating loop - at least I think adding a buffer tank is the way to go for me, still researching… #heatpunks
