Solar Thermal Water Heater - High-efficiency Thermosyphon And Forced Circulation Systems | Reliable Natural Circulation Suitable For Domestic & Industrial Use Up To 4000 Lpd

Owing to superb talent of our team of dexterous and experienced professionals There are two types of solar water heating systems based on type of circulation;

1. Thermosyphon 2.
Forced circulation
All domestic and industrial systems upto 4000 LPD (liters per day) @ 60 deg.C; works on the principle of thermosyphon. Industrial systems beyond 4000 LPD to any capacity will work on forced circulation principle.
Thermosyphon system:
The system works on a principle called "THERMOSYPHON" (Natural circulation).Due to density difference between the cold & hot Water the lighter hot water flows up into the tank and the heavier cold water enters the collector.
Solar radiation incident on the collector panels heats the absorber. This heat is transferred to the water contained in the absorber & becomes less dense than the water in the storage tank. Hot water starts rising and settles at the top of the storage tank. Simultaneously cold water descends to the collector absorber tubes gets heated up and the cycle repeats.
The circulation in the system during the heating process is purely due to the difference of density only. There is no other mechanical moving part hence the system reliability is very high.
At the end of the day when radiation is zero (after dark / sun set) the collector will contain heavier cold water and the tank will have lighter hot water. This will ensure that there will be no circulation during night & hence no conduction losses on account of this.
