500L 1000L 1500L 2000L 3000L Commercial and Industrial Solar Water Heating System

500L 1000L 1500L 2000L 3000L Commercial and Industrial Solar Water Heater System for factories, hotels, schools, and hospitals. Available in 500L to 3000L capacity, this system uses high-efficiency evacuated tubes and insulated storage tanks to deliver consistent hot water while reducing energy costs. Ideal for large-scale applications and continuous hot water use.

Commercial and Industrial Solar Water Heater System Working Principle:

1. The storage tank is first filled with cold water, and the collector loop is filled and primed.
2. Solar radiation heats the water inside the vacuum tubes of the collector.
3. When the controller senses that the temperature difference between the collector and the storage tank has reached the set value, it automatically starts the circulation pump.
4. The pump circulates water through the loop, transferring heat from the collector to the tank.
5. Heated water enters the storage tank, while cooler water from the bottom of the tank flows back into the collector.
6. If the tank temperature does not reach the set value, the auxiliary electric heater automatically switches on to provide additional heating.
7. When the temperature difference falls below the set threshold, the circulation pump stops automatically.
8. If the stored water still hasn’t reached the target temperature, the auxiliary heater continues operating until the required level is achieved.
9. Once the water reaches the desired temperature, it is stored in the tank, ready for use.

The System Typically Consists of:

1. Vacuum Tube Collectors:
* High-efficiency evacuated tubes that absorb solar energy and transfer heat to the water or heat pipe inside the collector.
* Can be direct-flow (water inside tube) or heat-pipe type.

2.Storage Tank/Hot Water Tank:
* Large-capacity tank (stainless steel or coated steel) that stores heated water and maintains temperature.
* Often comes with internal insulation to minimize heat loss.

3.Heat Transfer & Circulation System:
* Thermosiphon circulation (gravity-based) or pump-assisted closed-loop circulation with a heat exchanger.
* Transfers heat from the vacuum tubes to the storage tank efficiently.

4.Piping and Insulation:
* Heat-resistant, insulated pipes connecting collectors and tank, preventing heat loss.

5.Control System:
* Solar controller, temperature sensors, and timers to monitor and regulate water temperature.

6.Safety Devices:
* Pressure relief valves, anti-scald devices, expansion tanks, and check valves.

7.Mounting Structure:
* Roof or ground-mounted frames that hold vacuum tubes at optimal angles for sunlight absorption.

8.Optional Auxiliary Heater:
* Electric or gas backup heater to guarantee hot water supply during cloudy days or high-demand periods.

PUN201 Hot Water Booster Pump Specification:

PUN series water pump is a kind of hot and cold water circulating pump. It has its own overheat protector. When the temperature of motor winding exceeds the allowable temperature, the overheat protector will act and cut off the circuit. When the winding temperature drops to the allowable temperature range, the motor will restart.
