**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!
