2. India’s abundant sunshine makes solar water heaters an ideal, eco-friendly solution for hot water needs. But with various types, features, and brands available, picking the right one can be challenging. Here’s a guide on choosing the best solar water heater for your home. Understand the Types of Solar Water Heaters In India, the most common types of solar water heaters are Flat Plate Collectors (FPC) and Evacuated Tube Collectors (ETC). Each has its unique advantages and is suited for different weather and usage conditions: • Flat Plate Collectors (FPC): FPC systems have insulated boxes with a transparent glass cover and a series of copper pipes. They are robust, long-lasting, and work well in sunny areas. They’re also more resistant to hard water but are generally more expensive than ETC systems. • Evacuated Tube Collectors (ETC): ETC systems consist of glass tubes that absorb and retain heat effectively, making them more efficient in colder regions and during cloudy days. They’re typically more affordable than FPCs but might have durability issues in extreme climates. Consider the climate in your region, your budget, and water quality to determine which type would be best for your home. info@mehargroup.com

3. Calculate Your Hot Water Requirement Before purchasing a solar water heater, assess how much hot water you’ll need daily. This will help you choose an appropriately sized unit: • Household Size: A family of 4-6 typically needs a water heater with a capacity between 150-200 liters. For larger families, consider a system with a capacity of 300 liters or more. • Usage Patterns: Factor in your hot water usage. If you need hot water throughout the day, a higher-capacity system may be necessary. For occasional or morning-only usage, a smaller unit should suffice. A rough estimate is 25-30 liters per person per day. Multiply this by the number of family members to determine the appropriate capacity. info@mehargroup.com

4. Consider Water Quality in Your Area Water quality significantly affects the durability and performance of a solar water heater. In areas with hard water, the minerals can cause scaling, which reduces efficiency over time. Here’s what you should know: • FPC Systems: More resistant to hard water, as they use metal pipes less prone to scaling. • ETC Systems: Can be susceptible to scaling and may require more frequent cleaning or a water softener. Some ETC models now have anti-scaling features to counter this issue. If your area has hard water, invest in an FPC model or one with anti-scaling technology. info@mehargroup.com

5. Calculate the Return on Investment (ROI) Though solar water heaters involve a significant initial cost, they can yield long-term savings by reducing your electricity or gas bills: • Initial Cost vs. Savings: High-efficiency models may cost more but offer faster payback through increased energy savings. • Subsidies: The Indian government sometimes provides subsidies for best solar water heater in India. Check if you’re eligible for any financial incentives that reduce the initial cost. A solar water heater can pay for itself within 4-6 years in terms of energy savings, making it an economically sound choice. info@mehargroup.com
