10 Key Factors To Consider Before Installing A Solar Water Heater

📖 Introduction

Thinking about installing a solar water heater? It’s one of the smartest decisions you can make for your home, PG, apartment, hospital, or guest house. A reliable solar water heating system not only reduces your electricity bills but also contributes to a greener environment.

But before you rush into buying one, there are important points you need to consider. In this guide, we’ll break down the 10 key factors to consider before installing a solar water heater, ensuring you choose the right system that delivers the best value for your money.

At Varistor Solar™, one of the top 10 solar water heater companies in India, we help customers make informed choices every day. This post will give you exactly what you need to know before investing.

🌞 1️⃣ Understand Your Hot Water Requirements

The very first step is to figure out how much hot water you actually need daily.

• A solar water heater 100 ltr price model might be enough for a small family.
• Larger homes, PGs, or hospitals might need solar water heater 200 litre price or higher capacity systems.

📌 Pro Tip: List down how many people will use hot water and for what purpose (bath, kitchen, hospital sterilizing, etc.)

🌞 2️⃣ Know Your Local Climate

Solar water heaters work best in sunny areas.

• If you live in places like Mysore, Jaipur, or Bangalore, a solar water heater in India is a great choice.
• In colder or cloudy regions, you may need a backup electric or gas heater.

✅ Varistor Solar™ offers customized solutions for all weather conditions.

🌞 3️⃣ Choose Between ETC and FPC Collectors

Understand the difference between Evacuated Tube Collectors (ETC) and Flat Plate Collectors (FPC):

• ETC: Cheaper, better for colder regions, easy maintenance.
• FPC: More durable, better for hard water, longer lifespan.

Varistor Solar™ provides both with excellent warranties.

🌞 4️⃣ Check Available Roof Space and Structure

A solar water heating system needs proper roof space with good sun exposure.

• South-facing roofs are ideal.
• Ensure the roof is strong enough to hold the system’s weight, especially for large solar geyser setups.

🌞 5️⃣ Compare Solar Water Heater Prices

Prices vary by brand, capacity, and model:

• solar water heater 100 ltr price: ₹15,000–₹25,000
• solar water heater 200 litre price: ₹25,000–₹40,000
• Larger units: ₹40,000–₹1,20,000

Compare solar heater price options from top brands like Varistor Solar™ for the best value.

🌞 6️⃣ Consider Water Quality

If you have hard water or high mineral content:

• Go for FPC systems with antifreeze technology.
• Or choose ETC models with glass-lined tanks to resist corrosion.

✅ Varistor Solar™ water heaters are specially designed for hard water areas.

🌞 7️⃣ Evaluate System Warranty and Support

Always check:

• Warranty period (preferably 5–10 years)
• Availability of after-sales service
• Spare parts accessibility

Varistor Solar™ offers unmatched after-sales support and maintenance services across India.

🌞 8️⃣ Calculate Energy Savings and Payback Period

A typical solar water heater can cut your water heating costs by 60–80%.

📌 Example:
A solar water heater 200 litre price unit might cost ₹30,000 but can save up to ₹18,000 annually on electricity, meaning it pays for itself in just 1.5 years.

🌞 9️⃣ Check for Government Subsidies

Several Indian states offer government subsidies on solar water heaters.

✅ Varistor Solar™ helps customers with subsidy applications to reduce the upfront solar geyser prices even more.

🌞 🔟 Choose a Trusted Brand

Finally — always go with a reliable, experienced company.
✅ Choose a brand known for quality, service, and performance.
