Case Studies: Summerhouse in Gothenburg, Sweden
Here’s how the Ofen Pro performs in a summerhouse in Gothenburg, Sweden, under two scenarios.
Scenario 1: Wall Socket Power
- Setup: Ofen Pro plugged into a standard wall socket (1,100 W) at a summerhouse in Gothenburg.
- Electricity Cost: Sweden’s average rate is ~€0.25/kWh. Running 24/7: 1.1 kW x 8,760 hrs x €0.25 = €2,409/year.
- Bitcoin Earnings: At ~€0.263/kWh (4-yr avg), it earns 1.1 kW x 8,760 hrs x €0.263 = €2,535/year.
- Net Result: €2,535 (earnings) - €2,409 (cost) = €126 profit/year plus free heating for the 44 m² summerhouse.
Takeaway
Even on grid power, the Ofen Pro turns heating into a money-making opportunity.
Scenario 2: Excess Solar Energy
- Setup: Ofen Pro powered by excess solar energy at the same Gothenburg summerhouse (avg. 4 kWh/day surplus from a typical 5 kW solar system).
- Free Energy: Uses surplus solar power that would otherwise go to waste - no grid costs.
- Bitcoin Earnings: With 4 kWh/day available: 4 kWh x 365 days x €0.263/kWh = €383/year.
- Net Result: €383 profit/year plus free heating, all from sustainable energy.
Takeaway
Pairing with solar maximizes savings and sustainability, making your summerhouse a bitcoin-earning retreat. Numbers and calculations are exemplary ballpark and depend on various factors.
