Free home heating with Bitcoin miningwaste heat.
SunBit offers a new way to heat detached houses and larger properties by using Bitcoin mining waste heat and the revenue it generates. The solution suits properties with water-based radiators or underfloor heating.
SunBit in Kauppalehti.
Kauppalehti featured the system SunBit developed and the benefits it brings to home heating — Bitcoin mining waste heat can be used efficiently to heat a property, in some cases so well that the system generates a profit for the customer.
Bitcoin Boiler does what other heating systems can't: it turns heating costs into a revenue stream.
Heat your property for free with data-center waste heat.
Bitcoin mining is already a profitable business on its own — and it happens to produce waste heat. Why not use that heat to warm your home? Mining revenue covers the electricity costs, and heat is created for free as a by-product.
Four good reasons to get Bitcoin heating.
Affordable heating
No more worrying about high heating costs. In the best case you even earn side income by heating your home.
Part of sustainable development
Bitcoin mining improves the yield potential of solar panels. You can earn up to 5× more for your over-production compared to selling at the spot price.
Easy and hassle-free
Residents don't need to worry about mining, installation or maintenance. SunBit handles the full turnkey service — install, maintenance and remote management.
Heating that pays itself back
Unlike traditional systems, the savings from Bitcoin mining cover the investment quickly and offer the chance for extra revenue. A financially sound choice.
How can home heating run on Bitcoin mining?
A simple process that runs itself, year-round.
Mining uses electricity
One Bitcoin mining unit is 5 kW. In efficiency terms, miners are comparable to electric heating. The number of devices is sized to the property's heating demand.
Mining devices generate bitcoins
Miners maintain the Bitcoin blockchain and are rewarded for it. New devices average around €0.15 / kWh.
Mining produces waste heat
100 % of the electricity miners consume becomes heat — up to 60 °C. Our equipment suits properties with a water-based heating system.
The result
Mining revenue covers the electricity. Waste heat is created for free as a by-product. That's how we make home heating free.
A heating system that mines Bitcoin.
Bitcoin Boiler heats homes and properties with a water-based heating system. Water is heated to 60 °C, and any excess heat is rejected through an outdoor unit. From the tank, heat is used normally for domestic hot water and hydronic heating.

Installations across Finland — and Europe.
200 m² detached house
The first Bitcoin Boiler was installed alongside an old oil boiler as a hybrid solution. The outdoor unit enables summer cooling and better use of solar over-production.
180 m² detached house
District heating was replaced by mining. In addition to the boiler we installed a separate hot-water tank to secure domestic hot water. SunBit manages it remotely.
Commercial property
Our first international project in 2025. A local team carried out the install with SunBit's guidance.
Traditional heating vs. Bitcoin Boiler.
Conventional heating is expensive, and Bitcoin mining is technical. SunBit removes both problems with one solution — no technical know-how or crypto knowledge needed.
Traditional heating
- You pay for electricity, oil or district heat
- You only get heat
- €0 revenue, 100 % cost
Bitcoin Boiler
- You pay the same electricity as before
- You get heat and mining revenue
- Mining revenue covers the electricity — heat is free
How much does the SunBit heating system cost?
The SunBit heating system typically costs €14,350–22,300 depending on the property's heating capacity needs and equipment choices. The price is in line with other modern heating methods such as geothermal, and the system typically pays for itself in 3–6 years through mining income.
How much will I save on heating costs?
SunBit lowers your net heating costs, because you pay for the electricity to produce heat but receive mining income back at the same time. At best, mining produces more than the electricity used for heating costs, leaving you in profit on your heating.
How much will mining raise my electricity bill?
The mining units consume electricity, but the same amount of energy would go into heating anyway — the difference is that with SunBit, producing heat also generates mining income. When mining is profitable, the system can be run at full power even when there is no heating demand. In that case electricity consumption rises, but mining income rises more, meaning the more the units run, the more you save.
Do I need to understand bitcoin or mining?
No. SunBit handles the installation, upkeep, maintenance, and mining-related remote management for you — you need no experience with Bitcoin. You use the system just like any other heating.
What happens if the value of bitcoin falls?
The system heats your home regardless of the price of bitcoin — heating is not tied to the market and works like any other heating system. Market conditions only affect the mining income, that is, how quickly the system pays for itself.
