💡 Working Principle
The flat plate collector absorbs solar energy and the heat is transferred to the water tank through pump circulation. When the temperature difference between the collector and tank reaches the set value, the controller starts the circulation pump automatically for heat exchange.
Usually, an internal coil is pre-installed in the storage tank as a heat exchanger. A heat-transfer liquid circulates through the flat panel to the tank coil for heat exchange between the closed loop and main tank water. An additional tank coil could be used to form a closed circulation loop for room, floor, or pool heating.
🏠 Applications

❓ Frequently Asked Questions
What is the main advantage of a separate pressurized solar system?
The separate system allows the tank to be placed indoors (bathroom or equipment room) while collectors are on the roof. The pressurized design ensures stable water flow and uniform mixing of hot and cold water.
Can this system be used for floor heating?
Yes, by using an additional tank coil, the system can form a closed circulation loop specifically for room, floor, or even swimming pool heating.
What is the typical lead time for production?
Generally, it is 3-7 working days if the goods are in stock. For custom or large orders, it typically takes 15-25 working days depending on the quantity.
What kind of warranty do you provide?
We provide a 12-24 month warranty service. Specifically, 12 months for electrical components and accessories, and 24 months for the solar water heater unit.
Is the system protected against freezing?
Yes, the system uses secondary heat exchange with heat-transfer liquid in the collectors, which prevents freezing, scaling, and leakage in cold climates.
Do you offer customized solutions for large projects?
Absolutely. With over 20 years of engineering experience, we offer tailored solutions including technical consulting, system design, and commissioning for commercial and industrial applications.
