1️⃣ Energy Source

Solar Water Heater:

Uses energy from the sun through solar hot water panels (ETC or FPC) to heat water, storing it in a solar water heater tank. It’s renewable, eco-friendly, and free after installation.

Electric Water Heater:

Relies on electricity to heat water. While convenient, it consumes a lot of power, increasing your monthly bills.

✅ Winner: Solar Water Heater

2️⃣ Running Costs

Solar Water Heater:

Once installed, it uses zero electricity for daily water heating. The only cost is occasional maintenance, making it highly cost-effective.

Electric Water Heater:

Consumes significant electricity daily, especially during winters. Over time, this adds up to higher utility bills.

✅ Winner: Solar Water Heater

3️⃣ Installation Cost

Solar Water Heater:

The solar water heater price is higher upfront, ranging from ₹18,000 to ₹1,50,000, based on capacity and model. But this pays off quickly through energy savings.

Electric Water Heater:

Has a lower initial price, typically between ₹4,000 to ₹12,000, depending on brand and capacity.

✅ Winner: Electric Water Heater (if considering initial price only)

4️⃣ Lifespan and Maintenance

Solar Water Heater:

A good system, like those from Varistor Solar, lasts 15–20 years with minimal maintenance. Occasional cleaning of solar hot water panels and checking valves is enough.

Electric Water Heater:

Usually lasts 8–10 years. Requires more regular servicing and part replacements.

✅ Winner: Solar Water Heater

✅ Winner: Electric Water Heater (if you need instant heating)

6️⃣ Eco-Friendliness

Solar Water Heater:

Zero carbon emissions. Reduces dependency on electricity generated from fossil fuels. Perfect for sustainable living.

Electric Water Heater:

Consumes electricity generated largely from non-renewable sources. Contributes to higher carbon emissions.
