Efficient 20-Liter Mini Solar Water Heater For Rooftop Revolution


Traditional water heaters can be a drain on your electricity bill, often requiring up to 2000 watts to heat water. Enter the 20-liter mini solar water heater, a rooftop marvel that revolutionizes the way we think about heating water. This solar-powered geyser uses as little as 30 to 50 watts, offering a more sustainable and cost-effective solution for your hot water needs.

Design and Efficiency

The mini solar water heater is engineered for maximum efficiency, using a series of steel pipes coiled together to facilitate the flow of water. These pipes are directly heated by solar rays, thanks to a strategically placed metal plate painted black to absorb any rays that pass between the pipes. To further enhance its efficiency, the system incorporates two reflective sheets that focus additional solar rays onto the pipes, speeding up the heating process.

Water Circulation

A low-power water pump, requiring an external power supply of up to 50 watts, circulates water through the heating pipes and back into the storage tank. This continuous flow ensures that the water is consistently heated and ready for use. The water can be accessed through a third outlet, making the system not only energy-efficient but also highly convenient.


The approximate dimensions of this compact water heater are 550 x 440 x 400 mm (L x W x H), making it a perfect fit for any rooftop.


  • Energy-efficient, saving up to 99% of the energy compared to traditional heaters.
  • Quick heating time.
  • Compact and easy to install.
  • Sustainable and eco-friendly.

Price and Availability

The 20-liter solar water heater price is competitive, offering excellent value for its efficiency and durability. It is readily available through various outlets, both online and in stores near you.


The 20-liter mini solar water heater is a game-changer in the realm of sustainable living. Its efficient design and low power consumption make it an ideal choice for anyone looking to reduce their energy bills and carbon footprint.
