What is a Solar Water Heater?

A Solar Water Heater uses solar collectors mounted on your rooftop to absorb sunlight and convert it into heat. This heat is transferred to water, which is stored in an insulated tank for use whenever you need it.

Unlike electric geysers that consume significant electricity, a solar water heater runs entirely on free solar energy, making it the most cost-effective way to get hot water for bathing, cleaning, and cooking.

With advanced insulated tanks, hot water stays warm for 24–48 hours, ensuring availability even after sunset or on cloudy days.

How It Works

Simple, effective, and completely automatic.

1. Sunlight

Solar collectors on your rooftop absorb sunlight energy.

2. Heat Transfer

Water heats naturally as it passes through the collector tubes.

3. Storage

Hot water is stored in a heavily insulated tank to retain heat.

4. Hot Water

Hot water is delivered to your taps whenever you need it.

System Components

Premium quality materials for long-lasting performance.

Solar Collector

High-efficiency tubes or flat plates that absorb maximum solar heat.

Storage Tank

Double-walled insulated stainless steel tank to keep water hot for 24–48 hours.

Insulated Pipes

Thermally insulated piping to minimize heat loss during water transfer.

Support Structure

Heavy-duty galvanized frame angled for optimal sunlight exposure.

Safety Valve

Pressure relief valve for safe operation and overflow prevention.

Controller

Smart temperature controller with electric backup for cloudy days.

Frequently Asked Questions

How does a Solar Water Heater work?

Solar collectors absorb sunlight and transfer the heat to water flowing through them. The hot water rises naturally (thermosiphon principle) into an insulated storage tank, ready for use.

Does it work during winter?

Yes! Solar water heaters work throughout the year. In winter, the water temperature may be slightly lower, but our systems come with an optional electric backup heater for consistently hot water.

Does it work on cloudy days?

Solar collectors absorb diffused sunlight even on cloudy days, so the water will still heat up, though to a lower temperature. The insulated tank retains heat for 24–48 hours.

How much electricity can I save?

A typical household can save ₹1,500–₹4,000 per month on electricity bills by replacing electric geysers with a solar water heater. The system pays for itself in 2–3 years.

How much maintenance is required?

Minimal. An annual cleaning of the collector surface and periodic check of the plumbing connections is all that's needed. There are no moving parts to wear out.

How long does installation take?

A standard residential solar water heater installation takes just 4–6 hours. Commercial installations may take 1–2 days depending on capacity and plumbing complexity.

Which system is suitable for my home?

For most homes, a 100–200 LPD (Litres Per Day) ETC system is ideal. For larger families or buildings, we recommend 200–500 LPD systems. Our team will help you choose the perfect size based on your usage.
