Hot Water Powered by the Sun - Not the Grid
A solar water heater is a system in which solar thermal energy is used to heat water stored in an insulated tank - replacing conventional electric geysers that consume significant electricity every day. The heated water is available immediately on tap, at temperatures between 50°C and 80°C, throughout the day and into the evening.
At PSD Energy & Water Pure System, solar water heaters are supplied in Evacuated Tube Collector (ETC) and Flat Plate Collector (FPC) configurations - each suited to different installation environments, budgets, and usage patterns.
"An electric geyser consumes 2–3 units of electricity every day. A solar water heater eliminates that cost entirely - delivering savings of ₹2,000–₹3,500 per month for larger systems."
- PSD Energy, Karur
Hot Water at Up to 80°C
Solar water heaters are capable of heating water to temperatures of 60–80°C on sunny days - fully sufficient for bathing, cleaning, cooking, and industrial process applications.
Zero Electricity Running Cost
Once installed, solar water heaters operate entirely on solar energy - producing hot water at absolutely no recurring electricity expense throughout the system's 20-year life.
Works Year-Round in Tamil Nadu
With over 300 sunny days per year, Tamil Nadu is one of India's best regions for solar water heating. Even on partially cloudy days, effective heating is achieved.
BIS & MNRE Certified Systems
All solar water heaters supplied by PSD Energy are BIS-certified and eligible for subsidies under the MNRE Solar Water Heater scheme - ensuring quality and financial benefit.
ETC or FPC? The Right System for Your Needs
Two types of solar water heater technology are offered - each with distinct advantages for different applications. The best fit is recommended after a free site visit and consultation.
ETC - Evacuated Tube Collector
High Efficiency · All-Weather
ETC solar water heaters use vacuum-sealed glass tubes to capture solar thermal energy with minimal heat loss - making them highly effective even on winter mornings, foggy days, and overcast conditions.
- Higher efficiency in all weather
- Works on diffuse sunlight
- Lower heat loss due to vacuum
- Self-cleaning tube design
- Ideal for residential & hostels
FPC - Flat Plate Collector
Robust · Long-Lasting
FPC solar water heaters use a flat, tempered-glass covered absorber plate to capture solar energy. They are more robust, easier to maintain, and better suited to large-scale commercial and industrial deployments.
- More durable & longer life
- Better for continuous use
- Suitable for high-pressure systems
- Ideal for large capacities
- Lower maintenance requirement

Every System Includes Premium Components
Only tested, BIS-grade components are specified - because the reliability of a solar water heater over 20 years is directly determined by what is installed from the very first day.
Evacuated Tubes / Flat Plate Collector
High-efficiency solar collectors absorb solar radiation and transfer thermal energy to the heat-transfer fluid - with minimal heat loss through vacuum insulation or selective coatings.
Insulated Storage Tank
Hot water is stored in double-walled stainless steel tanks with high-grade polyurethane foam insulation - maintaining water temperature for 24–36 hours with minimal heat loss.
Header Manifold
The manifold connects all collector tubes to the storage tank - enabling balanced water flow and maximising heat collection across the full collector array.
Electric Backup Element
An optional electric heating element is integrated for days when solar radiation is insufficient - ensuring uninterrupted hot water availability on exceptionally cloudy or rainy days.
Temperature & Pressure Relief Valve
Safety valves are fitted to every installation - automatically venting excess pressure and preventing overheating to protect both the system and its users.
Mounting Frame & Plumbing
Galvanised or SS mounting structures are fabricated and installed to orient the collectors at the optimal tilt angle - with all plumbing done using CPVC or SS piping.
