Affordable Yet Powerful
Get hot water year-round without breaking the bank. This unit is more budget-friendly than pressurized systems but still delivers reliable performance.
Zero Energy Bills for Heating Water
Cut down your electricity costs significantly — solar energy does all the work with no ongoing expenses.
Safe for Direct Use
The open-loop design heats water directly in the tank and delivers it straight to your taps — great for basic bathrooms, kitchens, and laundry use.
Low Maintenance
Fewer moving parts and no pressure-based fittings mean reduced wear and tear, less scaling, and easier cleaning.
Perfect for Rural Homes & Urban Apartments with Overhead Tanks
No need for pumps or high-pressure systems. Just connect it to your storage tank and start enjoying solar hot water.
The evacuated tubes absorb sunlight and transfer the heat directly to the water inside the stainless steel tank. As the sun heats the water during the day, the well-insulated tank keeps it warm for hours. When you open a tap, hot water flows out naturally due to gravity, while cold water from your overhead tank replaces it.
An optional electric rod can be activated during cold or rainy days to maintain your preferred temperature.
