Solar Hot Water System Description:

Exactly, INLIGHT glass-tube collector system is a large-scale solar water heating system that provides hot water from an array of glass-tube solar collectors.


It consists of a solar collecting system, a water storage system, a control system and a pump system. When hot water in glass-tube solar collector is 10 degrees higher than tank water temperature, the controller will start circulation pump to refill cold water from tank to the collector, the same time hot water in the collector will go back to the storage tank, when water temperature difference is lower than 3 degrees, circulation pump will stop.


If the tank water temperature does not reach the set value at the set time, auxiliary heating device will start to work till the total water in storage tank get heated as expected.


Our  company do not only offer OEM manufacturing service according to different requirements and conditions, but also offer professional solutions and technical support and after-sale services free of charge.

INLIGHT glass-tube collector water heating system is commonly used in supplying continuous hot water for hotels, schools, factories, hospitals, swimming pools or some other large organizations or communities requiring continuous hot water supply.

Features & Advantages:

1. Daily Hot water output from 1 ton to 1,000 tons.


2. INLIGHT glass-tube collector water heating system is the most economical system with stable and reliable performance, cost can be recovered within 2 to 3 years and the solar system is almost free in use in next 10 to 20 years.


3. The system takes solar irradiation as the heat energy, energy saving is up to 80%.

4. Reducing the emission of greenhouse gas day after day, the system is environment-friendly which should be advocated by every countries.

5. INLIGHT glass-tube collector water heating system can be designed to combine with conditional water heating devices such as gas boilers, oil boilers, air-source heat pumps, electric heaters, supplying hot water 24 hours all day long.

6. The system can be designed with indoor pipeline circulation, no need to release cold water in pipeline before getting hot water from taps, also the system can be designed to supply constant-temperature hot water, also the time for hot water supply can also be set in the control unit.

7. INLIGHT glass-tube collector system can be customized according to actual building style and hot water requirements in different global locations.


8. INLIGHT glass-tube collector system can be used in areas with subzero weather anti-freeze system design and pipeline insulation. When the water in collector pipeline is lower than set  value (such as 5 degrees ), controller will control circulation pump to feed hot water from tank to the collector pipeline, when water in collector pipeline is higher than set value (such as 10 degrees ), the pump will stop, in this way the collector pipeline is protected from freezing.


9. INLIGHT solar water heating system is designed with overheat protection, lightning protection, wind-resistance, reliability and safety.


10. Although INLIGHT glass-tube collector system is non-pressurized with a pressure pump in the hot water pipeline you can get fixed hot water pressure in every water taps. 


11. INLIGHT glass-tube solar collector has many types for customer choosing, like one-wing and two-wing collector, rectangular and cylinder manifold, color steel and aluzinc and stainless steel collector.
