Split Pressurized Solar Water Heater adopts a split pressure-bearing design, with the collector and water tank installed independently. It is suitable for high-rise buildings, villas and other scenes, breaking through the water pressure limit of traditional solar water heaters. Even in an extremely cold environment of -35℃, it can stably output 55℃ hot water. The double-circulation copper-nickel alloy heat exchange technology has a thermal efficiency of 96%, and with the AI pressure adaptive system, the water pressure fluctuation is accurately controlled to ±0.05bar.

Product advantages and features

The collector is separated from the water storage tank: the water storage tank can be flexibly installed in any position indoors or outdoors, and the collector can be installed on a sloping or flat roof.
Modular design: The collectors can be combined according to needs to meet domestic or commercial water needs.
Intelligent control system: Automatically adjust the temperature, provide all-weather hot water supply, and have anti-freeze function.
Anti-freeze design: There is no water inside the collector, and the system controller has an anti-freeze function, which can operate normally even in extremely cold environments.
All-weather operation: Even on rainy days, the system can ensure hot water supply through the electric heating function.

Working Principle

The solar collector absorbs sunlight and converts it into heat energy.
When the collector temperature reaches the set value, the controller automatically starts the circulation pump.
The circulation pump circulates the heat transfer fluid in the system and transfers the heat to the water storage tank through the heat exchanger.
When the water storage tank temperature does not reach the set value, the electric heating element automatically starts to ensure hot water supply.

Multi-scenario empirical cases

Dubai Hotel Project: In a high temperature environment of 50℃, an average of 150 tons of 85℃ hot water is supplied daily, replacing fuel boilers, saving $410,000 in energy costs annually.
Nordic regional heating: The Gothenburg community in Sweden uses a split system to preheat central heating water, increasing thermal efficiency by 32% in winter and reducing CO₂ emissions by 420 tons per year.
