Last year when I first started getting into crypto mining, my 40+ graphics cards were an amazing thing during the Australian winter (June-August), warming my entire house even on 2C mornings.
But now French startup Qarnot has unveiled their new QC-1, a crypto heater that generates heat while mining cryptocurrency. Qarnot's upcoming QC-1 will be powered by two of AMD's Radeon RX 580s - specifically, SAPPHIRE's Nitro RX 580.

QC-1 will consume up to 500W of power, and has been designed for 20m2. Qarnot says that the QC-1 will make around $120 per month at the current price of Ethereum.

Price wise, the QC-1 heater will cost $3560 and would be an interesting investment into your house.
Qarnot explains:
Earn crypto currency while heating
- The heat of your QC-1 is generated by the 2 graphics cards embedded in the device and mining crypto-currencies or blockchain transactions: while heating, you create money.
- You can watch in real-time how crypto markets are trending, on your mobile app and on your QC-1 LEDs.
Noiseless & high-end design
- The QC-1 crypto heater is the only one in the market to be perfectly noiseless!
- It doesn't embed any mobile part (no fans, no hard drives). This system, developed by Qarnot, is IP-protected.
