🔥ЕКОНОМІЯ НА ОПАЛЕННІ: +600 Вт щогодини своїми руками

In this video I show a homemade heat exchanger and real measurements, without marketing and fairy tales. 📊 Actual data: Outdoor temperature: –4.3 °C Exhaust from the house: 17 °C Inflow into the house: 11.2 °C Efficiency by temperature ≈ 73% Heat gain: ≈ +600 W per hour 🌬️ Ventilation: 5 fans 12″, 12 V 0.3 A 3 for supply, 2 for exhaust Continuous operation at 8 V Automatic switch to 12 V at CO₂ - 1000 ppm Throughput: ≈120–200 m³/h 🏠 Conditions: House 100 m² 2 adults, 3 children and a large dog CO₂ level stably below 1000 ppm ⚡ Electricity consumption: only 10–18 W, with hundreds of watts of heat return. This is an example of how recuperation really saves on heating, without heating elements, gas and expensive factory solutions. The video is filmed from practical experience - without theory from the Internet, only what really works.
