Bitcoin earnings vary with network conditions, Bitcoin's price, and your electricity rate — they are not guaranteed. Estimate yours with the calculator.

Heatoshi uses a patent-pending hydronic system to capture the heat naturally generated by Bitcoin proof-of-work computation. That heat is circulated through a closed-loop system to warm your home, pool, barn, or hot tub — while the same computation quietly earns Bitcoin around the clock.

Why you'll love it

  • Every watt works twice — useful heat plus Bitcoin earnings from the same electricity
  • Whisper-quiet closed-loop hydronic system (under 45 dB)
  • Set-and-forget control from the Heatoshi app
  • Modular and upgradable — improves with age instead of becoming obsolete

Just set your target temperature in the Heatoshi app and Heatoshi manages the rest — adjusting output, monitoring performance, and earning automatically.

Heatoshi is designed for a straightforward install — simple enough for any qualified local contractor. A plumber ties it into your heating loop, an electrician wires the dedicated circuit, and most installs are completed within a day.

What to expect

  1. Confirm your panel capacity and plumbing setup — we provide a simple checklist to share with your contractor.
  2. Your contractor connects Heatoshi to your heating loop — existing hydronic systems tie straight in; pools and hot tubs connect directly.
  3. Connections and performance are verified, and the Heatoshi app is paired.
  4. You pick your target temperature and enjoy the warmth.

Before you order

  • Works with existing hydronic (water-based) heating; pools and hot tubs connect directly. Your contractor can assess other setups.
  • Requires a dedicated 220V/30A circuit (Heatoshi Pro: 60A) — a routine job for any licensed electrician.
  • No specialized training required — any qualified local plumber or electrician can handle the install.
  • $500 flat-rate shipping within the United States; pay by credit card, Apple Pay, or Bitcoin (3.5% discount) at checkout.
