Thermosiphon Seasonal Solar Collector is one of the simplest and most affordable solar water heaters. They are characterized by their straightforward design and low cost. The main component of the solar collector consists of glass vacuum tubes, positioned at a specific angle and connected to a storage tank.
The circulation of the heat transfer fluid in the system occurs due to natural convection: when the water in the collector tubes heats up, it becomes lighter and rises to the top of the tank, while the cold water descends to the bottom of the tubes.
Altek solar water heaters are designed as a standalone installation that simultaneously serves as a solar receiver and a storage tank for heating water.
The solar water heater belongs to non-pressurized thermosiphon systems (natural convection) for water heating and is intended for SEASONAL use. They are operated in conditions of positive outdoor air temperatures. The recommended operating temperature of the environment is from 0°C to +50°C.
