Split Flat Panel Solar Water Heater

This system is specially designed for households and villas. It consists of the following parts: flat panel solar collector, storage water tank, solar working station, and expansion vessel.

Split Solar Water Heater System
Solar Water Heater Components
Key Specialities
  • Collector separate with water tank, system works by pump circulation.
  • Automatic controlling system, reliable operation, supply constant water temperature.
  • Water tank can put anywhere inside house, avoid gradual rust and last long lifetime.
  • Collector can be installed wherever available like balcony, wall, roof etc.
  • Easy and convenient installation and operation, unified with the building completely.
Working Principle

Adopt the temperature difference circulation, controller operates whole system automatically.

1
Pump starts circulation when temperature difference between collector and water reaches the set value.
2
Pump stops circulation once the temperature difference is lower than the set value.
3
The circulation pump makes heat-conducting liquid circulate automatically.
4
The heat-conducting liquid transfers heat to the water tank by copper heat exchanger.
5
Assistant heating element will start if hot water does not reach set value.

Frequently Asked Questions
What are the main advantages of a split solar water heater?
The split design allows the collector to be placed on the roof or balcony while the tank is kept indoors, reducing heat loss and protecting the tank from outdoor elements, which extends its lifespan.
Does the system work on cloudy or rainy days?
Yes, the system includes an auxiliary electric heating element that automatically activates if the solar energy is insufficient to reach the set water temperature.
Is the water tank pressurized?
Yes, this is a pressurized system, which means you get strong water flow at the tap, similar to a standard electric or gas water heater.
What material is used for the inner tank?
The inner tank is constructed from high-grade SUS304-2B or 316L stainless steel, providing excellent corrosion resistance and hygiene for domestic water.
How is the temperature controlled?
The system uses an intelligent solar workstation (controller) that monitors the temperature difference between the collector and the tank to manage the circulation pump automatically.
Where can the solar collector be installed?
The flat panel collector is highly versatile and can be installed on flat roofs, pitched roofs, balconies, or even integrated into the building's wall.
