Detailed description of 21ENERGY Bitcoin Heater:

  • Bitcoin Heater S9x3 with 3 Bitmain Antminer S9
    Factory setting with 1,500 watts heating power
    15-18 TH/s mining performance
  • Whisper quiet (under 40 dB)
    With factory settings of 500 watts of heating power per Bitmain Antminer S9 installed, the 21ENERGY Bitcoin Heater is very quiet at less than 40 dB.
    The installed Bitmain Antminer S9 can also be operated with a higher wattage, but this increases the noise level.
  • Fan
    The Bitmain Antminer S9 originally has 120 millimeter fans installed. We replaced them with the best high-performance 140 millimeter fans available on the market – the Noctua NF-A14 industrialPPC-3000 PWM https://noctua.at/de/nf-a14-industrialppc-3000-pwm.
  • Air and dust filter
    Air, dust and acoustic filters are installed in the Bitcoin Heater on two levels. The dust filter on the bottom is easily accessible by flipping the Bitcoin Heater over and can be vacuumed if needed. These filters perfectly protect the Bitmain Antminer S9 from dust.
  • High heating cost savings potential
    The savings potential depends on the following two variables:

  • Innovative combination of convection and radiant heating
    The upper part is pleasantly warm and provides radiant heat. At the same time, warm air flows out.
  • Modern design
    Heater has the shape of an octagon (8-corner) made of galvanized sheet, painted black matte (can be perfectly used as a bar table or side table).
  • High quality & durable construction
    The galvanized sheet is designed for very durable operation. Galvanizing perfectly protects the sheet from corrosion.
  • Dimensions & Weight
    Height 102 cm
    Diameter lid 62 cm or housing 55 cm
    Weight 53 / 59 / 65 kg (depending on version).
  • Plug & Play Commissioning
    Bitcoin Heater S9x is user-friendly and easy to put into operation. During the first start-up, you have to enter the WLAN password once to connect the Bitcoin Heater to the Internet. The built-in WLAN repeater simultaneously improves the WLAN network on site.
  • Braiins Mining Pool
    The Bitcoin Heater comes with a Braiins Mining Pool account. The installed Bitcoin Bitmain Antminer S9 are already completely pre-configured.
    With the delivered username and password you can either log in directly on the website https://pool.braiins.com/login/ or download the BraiinsPool app for Android or iOS and you can see how much Bitcoin the Bitcoin Heater has already mined.
    In the Braiins Mining Pool account, you can easily make withdrawals to the desired Bitcoin address.
    In the future, it will be possible to have the mined Bitcoin automatically paid out in euros to one’s bank account once a month.
    Of course, you can also deposit your own Mining Pool account – nobody is obliged to use the preset Braiins account.
  • Upgradepath
    The 21ENERGY Bitcoin Heater is designed to fit almost all popular future Bitcoin miners in the metal case. So in a few years you can order an adapter kit with e.g. a Bitmain Antminer S19 from our online store and upgrade your heater.
  • Up to 9 tons of CO2 savings per year
    compared to heaters based on other energy sources such as fuel oil and gas – depending on the electricity mix used to power the 21ENERGY Bitcoin Heater….
  • CE – certified
    The product is CE certified and approved for the whole EU.
    The device is multi-grounded and designed for maximum safety. The installed air & acoustic filters have fire protection class B1 (flame retardant) and the fire load has been reduced to an absolute minimum (plastic fan heaters have a much higher fire load).
  • Made in Austria
    The 21ENERGY Bitcoin Heater S9x was designed in Austria. The high-quality black matte lacquered housing of the Bitcoin Heater is produced in Tyrol. All individual parts are assembled in Tyrol. Some individual parts such as the Bitmain Antminer S9, WLAN Repeater and other small parts are purchased externally and were not produced in Austria.
