Oil vs. Bitcoin Heating: End Your Dependency on Fossil Imports
The Strait of Hormuz has been effectively closed to commercial shipping for ten weeks. Oil throughput has dropped to just 15% of normal levels — 1.5 million tonnes per day instead of the usual 10.3 million. This is the most severe energy supply disruption since the 1973 embargo, and it is hitting Europe's oil-dependent households hardest.
In Episode 04 of The MAXX Show, 21energy CEO Maximilian Obwexer breaks down the hard numbers behind Europe's energy vulnerability, explains why oil heating has become a serious liability, and outlines what households can do before winter begins.
What Is Happening at the Strait of Hormuz?
Under normal conditions, approximately 20 million barrels of oil pass through the Strait of Hormuz every day. That represents 21% of the world's oil supply, 25% of global LNG, and 30% of the world's fertilizer shipments. The current blockade has reduced this flow to a fraction of its normal capacity.
Middle East floating crude reserves crashed by 67% in a single week. There is no bypass route for this chokepoint. For Europe, the situation is particularly critical: 12 to 14% of European LNG imports originate from Qatar, all of which must transit through Hormuz.
Why Oil Heating Is Now a Liability
For millions of households across Germany, Austria, and Switzerland, heating still depends on imported oil and gas. The Hormuz blockade exposes just how fragile that dependency is.
| Country | Fossil Import Dependency | Key Risk Factor |
|---|---|---|
| Germany | ~65% | Gas storage at 27.9%, 40 points below 5-year average |
| Austria | ~62% | Heating oil at EUR 158.78/100L, near Ukraine war peak |
| Switzerland | ~75% | Highest dependency in the region, limited domestic production |
Germany's gas storage levels sit at just 27.9% capacity for May, a full 40 percentage points below the five-year average. In Austria, heating oil has climbed to EUR 158.78 per 100 liters, approaching the peak levels seen during the Ukraine conflict. But unlike 2022, this spike is happening before the heating season even starts, with reserves already depleted.
Every household that heats with oil or gas is directly exposed to geopolitical events thousands of kilometers away. The Hormuz crisis is not an anomaly. It is a reminder that fossil fuel supply chains run through some of the most volatile regions on earth.
Replacing Oil Heating: Why Now Is the Time
The window to act is closing. With 142 days until October 1st, households that rely on oil heating face a decision: lock in refill prices at crisis-level rates, or start transitioning away from fossil fuel dependency altogether.
A Bitcoin heater offers a fundamentally different model. Instead of burning imported oil, it uses ASIC mining hardware to convert electricity into heat. The waste heat from Bitcoin mining becomes your primary heating source. And unlike oil, the system does not just consume energy, it also generates revenue in Bitcoin while keeping your home warm.
This is not about replacing one fuel with another. It is about removing geopolitical supply chain risk from your household entirely. A Bitcoin heater runs on electricity, which can come from any source: grid, solar PV, or a combination.
Bitcoin Heater vs. Oil Heating: A Direct Comparison
| Oil Heating | Bitcoin Heater | |
|---|---|---|
| Fuel source | Imported crude oil | Electricity (any source) |
| Geopolitical exposure | High. Dependent on global supply chains | None. Runs on local electricity |
| Price volatility | Directly tied to oil markets | Electricity prices, partially offset by Bitcoin revenue |
| Revenue generation | None | Earns Bitcoin while heating |
| Works with solar PV | No | Yes. Ideal for surplus mining |
| CO₂ emissions | High | Depends on electricity source, zero with renewables |
Five Things You Can Do Before Winter
- Check your heating oil tank now. If you still depend on oil, lock in refill prices before autumn demand spikes push costs even higher.
- Review your electricity contract. Look for rate locks and consider switching to providers with fixed-price options to protect against winter volatility.
- Audit your heating system's supply chain. If your fuel transits through geopolitical chokepoints, you are carrying supply chain risk in your basement.
- Consider solar PV surplus mining. If you already have solar panels, you can generate Bitcoin income from excess electricity production during summer months instead of feeding it back to the grid at low rates.
- Explore Bitcoin heating as a long-term replacement for oil. A system that earns revenue while heating your home eliminates fossil fuel dependency entirely.
21energy Field Test: Bitcoin Central Heating in Tyrol
Starting in June 2026, 21energy will launch a field test of its Bitcoin central heating system in Tyrol, Austria. Pilot spots are available for Tyrolean households interested in replacing or supplementing their existing oil or gas heating with a system that mines Bitcoin while keeping their home warm.
The field test will provide real-world performance data across Austrian alpine conditions, including electricity consumption, heating output, and Bitcoin revenue generation throughout the heating season.
