Altek SD-T2L-15 Solar Collector

The Altek SD-T2L-15 solar collector is an innovative alternative system for heating water, providing hot water supply during the summer months, from April to November. It’s perfect for outdoor showers, as well as for your home or cottage. The system can also supply hot water for a summer pool and is used in greenhouses and conservatories. This solar collector belongs to the category of non-pressurized vacuum solar systems.

Usage of SD-T2L-15

The thermosiphon solar water heater consists of a tank (accumulator) and a solar collector connected to the tank. The transfer between the reservoir and the collector is regulated by gravity (the density of hot water is lower than that of cold water). Instead of a pump, the pressure difference between hot and cold water is used as the driving energy. This is the “thermosiphon principle.” For the system to work, the collector (heat generator) must be positioned below the reservoir (heat consumer). The heat transfer fluid is heated inside the solar collector. The hot liquid in the collector is lower than the cold liquid in the reservoir above the collector. As soon as the hot liquid rises, gravitational circulation begins. Inside the cylinder, the heated medium transfers its heat to the stored hot water system, and then, after cooling, returns to the lowest point in the collector circuit.
