Waste heat from data computing, put to good use.
A heating system that mines Bitcoin. Forget mere savings — we turn heating into a source of revenue. Bitcoin Boiler heats homes and properties with a water-based heating system. Water is heated to 60 °C. If more heat is produced than the property needs, the excess heat is pushed out through a condenser. From the tank, heat is used normally for domestic hot water and hydronic heating.

Depending on the property, a separate hot water tank and condenser may also be required, bringing the price to approximately €18,150 + VAT. Mining hardware (e.g. Antminer S21 XP Hyd (473 TH/s)) is priced on the order date. The final package is always tailored to the property.
To buy a Bitcoin Boiler you don't need to know anything about Bitcoin, IT or mining. We handle installation, maintenance, service and remote management of the mining.

The Bitcoin Boiler in practice
Can the Bitcoin Boiler be installed alongside an existing heating system?
Yes. The Bitcoin Boiler can be installed as a hybrid system alongside an existing oil, electric, wood-fired or geothermal heating system without removing the old boiler. It connects to the property's hydronic heating network and hot-water tank, allowing SunBit to serve as the primary heat source while the existing system remains available as backup during the coldest peaks.
Is the Bitcoin Boiler noisy?
No. The Bitcoin Boiler uses quiet liquid cooling, so the indoor unit is nearly silent and comparable in sound level to a normal home utility room. The outdoor condenser that removes excess heat is similar in sound and appearance to a conventional air-source heat pump outdoor unit.
How much space does the system require in the utility room?
The indoor unit is a compact upright unit with a footprint of approximately 0.5 m², and it fits in a typical utility room, boiler room or basement. If a separate 500-litre hot-water tank is installed, the recommended free floor area is approximately 1.5–2 m². The outdoor unit is installed on an exterior wall or a ground stand.
How long does installation take, and will the heating be interrupted?
Installation in a detached house typically takes 1–2 working days. Because the equipment can connect directly to the existing hydronic system, any interruption to heating and domestic hot water during the plumbing work usually lasts only a few hours. The turn-key installation includes both plumbing and electrical work.
Does using the system require technical or cryptocurrency expertise?
Not at all. The Bitcoin Boiler is delivered as a turn-key service: SunBit handles 24/7 remote management, automatic power control and mining optimisation. For the user, heating works fully automatically, just like any modern heating system.
