Solar collector
The diagram represents the process of water heating in a double system: by means of anti-freeze fluid, which uses the solar energy to warm water up, and of the boiler. Generally, both of them supplement each other: if the weather is cloudy, the boiler can help, whereas if there are some problems with electricity – the major source of boiler’s work – water can be heated by the Sun.
Coldwater fills the tank where tubes of the boiler and the solar heating system coil. The system with the Sun energy consists of a closed pipe with anti-freeze fluid inside it. The controller regulates how cold fluid is pumped to the solar collector which is located on the top where it can consume direct rays of the Sun. When anti-freeze fluid leaves this collector, it is already heated. Then, it proceeds down right to the tank where it emits heat to make cold water hotter. From this tank water goes directly to taps.
Overall, the double-heating system reliably provides people with hot water regardless of the weather.
