Releasing Efficiency with SIDITE's Double Inner Tank Pressurized Solar Water Heater

Energy saving and green heating are no longer an option—they are the requirement in this new age. At SIDITE Energy Co., Ltd., we continue to innovate solar thermal technology to meet the diversified needs of residential, commercial, and industrial complexes worldwide. Our most reliable one among them is the SD-P Pressurized Double Inner Tank Solar Water Heater, designed with long-lasting performance, safety, and simplicity in mind.

Why a Double Inner Tank Design?

As opposed to common solar water heaters, the SD-P model consists of two separate inner tanks:

First inner tank (non-pressurized): It acts as a heat exchanger, providing a smooth energy transition.

Second inner tank (pressurized): It provides the real hot water source to end users, providing even pressure and safer usage.

Such isolation allows the system to provide hot water sooner and automatically, without experiencing common issues like overheating or unstable pressure.

Key Features & Benefits

Tap water pressure advantage – ideal for municipal water supply compatibility (0.6 MPa).

Direct and full automatic operation – simple installation, simple maintenance.

Rapid heating – vacuum tubes efficiently capture sunlight and convert it to heat energy.

Direct connection – without the need for an independent circulation pump.

User protection – water is supplied only from the pressurized tank, preventing direct drawing from the non-pressurized tank.

Flexible applications – ideal for villas, hotels, schools, and other commercial projects.
