Paying for heat is so last century

The heater that pays you back.

Heatoshi is the world's first self-contained residential hydronic heater based on computationally generated heat. Set a temperature. The patent-pending system inside warms your water loop and earns rewards for the work it does. Have Fun Staying Warm™.

How it works

Same heat. Different element.

  1. Set your target temperature. In the app, like any thermostat. Heatoshi runs its hardware exactly hard enough to hold it.
  2. The hardware does paid work. Heatoshi runs Bitcoin proof-of-work, converting electricity to heat at near 100% efficiency.
  3. Water carries the heat. A small volume of pure water recirculates silently and carries the heat to a room, a pool, or a barn.
  4. Rewards offset the bill. The app shows target and current temperature, water flow, power draw, and average daily revenue side by side.

Designed for homes

Efficient

The patent-pending design converts electricity to heat at near 100% efficiency.

Economical

Bitcoin proof-of-work and energy recovery produce heat that can pay for itself.

Sustainable

Uses a small volume of pure water and recirculates it silently.

Upgradable

Modular hardware and software add abilities over time, so Heatoshi serves you for years.

Easy to use

Set a target temperature in the app. Heatoshi does the rest.

Scalable

Starts at 3.5 kW of heat and scales up.

Proven in the field

Our first prototype cut a pool's heating bill by 43%.

Installed as an electric pool heater, the prototype delivered a consistent 4.8 kW of heat. The production model is 80% smaller, with 30% lower cost of goods and 40% fewer critical parts.

Two pathways to ownership

Heatoshi is a productive asset that can pay itself off over time.

Full ownership

  • Retail purchase at full price
  • All rewards kept by the owner; no guarantee of profitability
  • Fully unlocked, expert mode

Heatoshi-subsidized

  • Service agreement, priced below retail
  • Rewards pay off the cost of the unit; guaranteed monthly return
  • Fully managed, novice mode
