**Bitcoin mining hot water heater pays for it's own upgrades while slow cooking Italian style lamb sandwiches!**


This hot water heater has been running for 6 months, keeping the water hot, mining bitcoin and cooking food. After only 3 months, it mined enough Bitcoin to pay for an upgraded heat exchanger allowing for higher sustained hashrate.


I've not been getting very creative with the sous-vide style cooking, but my favorite dish so far has been Italian "beef" style sandwiches with lamb neck. It seems like the longer it cooks the more flavorful it gets!




Overall, I'm shocked at how effective and efficient the Bitcoin mining hot water heater has been. It was so simple to convert the existing hot water heater without any major modifications (unlike my clothes dryer). Using canola oil as the dielectric fluid gives me a lot more confidence to use the contraption for cooking too. So far there is no indication of degradation of the canola oil after 6 months of continuous use!

Cooking hash-vide style rabbit ramen with Bitcoin mining hot water heater


The second meal cooked in the Bitcoin mining hot water heater is rabbit ramen soup. Rabbit grown and harvested right here at the homestead, along with these other ingredients from the homestead rabbit stock, garlic, and finally golden oyster mushrooms dehydrated with a Bitcoin miner. Soy sauce, rice vinegar, lemon, sesame oil, Japanese seven spice, salt, pepper, butter.


All ingredients went into a silicone bag and submerged in the hot canola oil tank of the bitcoin mining hot water heater for 3 days. Hard to beat mining Bitcoin, heating water, and cooking food all at the same time. I can get the water up to 150f out of the tap with only 1500w of power consumption for the total system, miner, pumps, and all!


Another super cool aspect of this mining setup is that it runs on 110v power instead of 220v. Not having access to a 220v circuit is often a limiting factor for pleb miners, especially when these sorts of applications don't always require so much power. By modifying the apw12 PSU and making a custom power cord, now I can plug the miner into an existing 110v circuit. It cost less than $20 to do the modification on the PSU plus using a modified apw12 vs a Loki + apw3++ allows for voltage attenuation and higher total power output.
