Detailed Product Description

ESS-300-30 Solar Water Heaters:

Working Principle

The collector absorbs solar energy and transmits it to the water tank through circulation. When the temperature of the collector reaches the set value, the controller turns on the circulation pump automatically.

The Characteristics

• Pre-assembled, pre-plumbed and wired.
• Simplicity of design with the highest achievable operating efficiencies.
• Instant hot water with comfortable pressure.
• Intelligent control system with complete function.
• Electric heater will flash on automatically if the water temperature is below the desired level.
• Flexibility of installing solar collectors on the roof or walls.
• No water in vacuum tube to freeze in winter.
• Very little maintenance and very low operating cost.
