Sí-Climate Mini (DIY Kit) – The Balcony Power Plant 2.0 for Heating & Passive Cooling

• Effectively reduce heating costs: Use stored solar heat to delay the cooling of your rooms and postpone the start of classic heating systems (pp. 1, 12).
• The Balcony Power Plant 2.0: While PV modules have an efficiency of approx. 20%, this system achieves 50-80% efficiency through direct thermal use (pp. 25-26).
• Easy DIY Construction: The system mainly consists of commercially available standard materials from hardware stores (e.g., PVC pipes, sand, aluminum boxes) (pp. 6, 27).
• Low Investment: Realize your own climate system with material costs between €700 and €1,500 (p. 4).
• Completely passive: In basic operation, the system requires no electricity, no pump, and no complex electronics – powered by pure physics (pp. 5, 20).

1. Harvest: A high-performance vacuum tube collector captures the sun's rays (p. 3).
2. Store: The heat is directed straight into a DIY sand storage unit. Sand is cheap, safe, and stores up to 5 kWh of thermal energy (pp. 20, 22).
3. Distribution: The natural thermo-siphon effect (chimney effect) creates a gentle airflow that transports the heat into your rooms without dust (pp. 13, 23).

• System type: Passive air & storage system (p. 5).
• Materials: Stainless steel, copper, sand, and mineral insulation materials (p. 12).
• Assembly time: Typically realizable by DIY enthusiasts in 1 to 3 days (p. 4)

The best of both worlds: A highly efficient, ready-to-use vacuum system generates heat, while the distribution in the house works entirely without pumps and solely through natural air movement. No complicated heating technology in the living space – just warm, clean air.

• Works in clouds & fog: Even on grey autumn and winter days, the system utilizes the residual radiation from the atmosphere.
• Maximum efficiency in winter: Since the vacuum in the tubes insulates like a thermos, the captured heat is not lost to the cold outside air – it goes directly into your storage.
• 30% more yield: Compared to flat-plate collectors, vacuum tubes deliver up to 30% more energy during the cold season.
