📑 Contents
✓ Key Advantages
- • Efficiency up to 92%
- • High performance in winter
- • 70% energy savings
- • 15-20 year lifespan
✗ Things to Consider
- • Initial cost is slightly high
- • Glass tubes can break
- • More space is required
- • Professional installation is recommended
✓ Advantages
1. High Efficiency (92%)
Thanks to vacuum insulation, up to 92% of solar radiation is absorbed and converted into heat. It generates 30-40% more energy than flat panels. This difference becomes particularly evident in winter months.
2. Excellent Winter Performance
It works efficiently down to -30°C. Even in cloudy and snowy weather, it produces hot water by making use of diffuse light. It is an ideal choice for cold regions of Turkey.
3. 70% Energy Savings
It provides up to 70% savings on electricity and natural gas bills. Savings between 15,000-25,000 TL per year are possible. You earn back your investment in 1-2 years.
4. Easy Maintenance and Repair
Tubes can be replaced individually. A malfunctioning tube does not affect the whole system. The replacement process is simple and economical.
5. Long Lifespan (15-20 Years)
Quality systems work smoothly for 15-20 years with regular maintenance. Our products are sold with a 2-year manufacturer warranty.
6. Zero Electricity Consumption
Thermosiphon systems do not require a pump. They work with completely natural circulation and are not affected by power outages.
7. Eco-Friendly
It uses a clean and renewable energy source. It reduces your carbon footprint, and you contribute to nature.
✗ Disadvantages
1. Initial Cost
There is a 20-30% higher initial cost compared to flat panels. However, we minimize this difference with wholesale prices from the manufacturer. Since savings are higher in the long run, the cost turns into an advantage.
2. Tube Breakage Risk
Glass tubes are sensitive to impact. Hail, falling large objects, or incorrect handling can cause breakage.
3. More Space Requirement
It requires slightly more roof space than flat panels. For a 24-tube system, a space of approximately 2x1.5m is required.
4. Professional Installation Recommended
Professional installation is recommended for the best performance. Incorrect installation reduces efficiency.
Flat Panel vs Vacuum Tube Comparison
