Riwatt flat plate thermosyphon integrating system is composed of solar flat plate collector,
water storage tank, bracket, circulation pipe and accessories. Due to thermosyphon
principle,the collector absorbs solar energy to heat the water inside,while the thermosyphon
circulation inside enables the heated water to flow into and be stored in the water tank.

A flat panel solar water heaters is a solar water heating system that uses energy from the sun to heat water. Solar energy is absorbed by flat plate collectors and transferred through pipes to a hot water storage tank, providing an eco-friendly and cost-effective alternative to conventional geysers.
Flat panel solar water heaters reduce electricity or gas consumption, lower utility bills, and decrease environmental pollution. They provide reliable hot water even during power outages or load shedding, making them a sustainable and independent solution for homes and businesses.
Depending on the model and local climate, a Flat Plate Solar Geyser can supply 50% to 90% of your household’s hot water requirements. By minimizing reliance on conventional heating, you save on energy costs while maintaining a steady hot water supply.
Most solar systems heat water to 55–65°C. For safety, domestic fixtures like baths and showers should not exceed 55°C, while kitchen sinks require at least 45°C to ensure proper sanitation and usability.
Well-insulated solar tanks retain heat for longer periods, ensuring hot water availability during mornings and evenings. Electrical backup systems can be used, preferably with a timer, to avoid peak electricity usage while maintaining hot water supply.
Standard geysers are often not compatible with solar collectors due to limited inlets and insufficient temperature tolerance. A professional evaluation is needed to determine whether your existing system can be adapted or if a new solar-compatible geyser is required.
Typical payback periods are around 5 years, depending on water consumption, household size, energy costs, and location. A solar geyser can offset up to 70% of a household’s electricity used for water heating, making it a cost-effective and sustainable investment.
