Solar Water Heaters What They Are and How They Work

1. Solar Water Heaters:WhatThey Are and How They Work • AnEco-FriendlySolution forHotWater Needs

2. Why Hot Water Needs an Upgrade • Hot water is essential for daily tasks: bathing, cleaning, laundry • Traditionalheatersconsume high electricity or gas • Rising energy bills and environmental concerns • Solution:Switchto solarwater heating systems

3. What Is a Solar Water Heater? • Asolar water heater is a system that uses energy from the sun to heat water for household use. Unlike traditionalelectric or gas heaters, it operates usingsolar panels (also called collectors), making it a more environmentally friendly and cost-saving option. • It’s commonly known as a solar geyser and is ideal for homes that want to reduce energy bills and minimize environmental impact. Once installed, it uses no fuel other than sunlight, providing an efficient, renewable, and low-maintenance source of hot water. • It’s perfect for daily needs like bathing, laundry, and cleaning—without depending on grid electricity or gas.

4. Key Benefits • 🌍 Eco-Friendly & Sustainable • Uses clean solar energy, reducing carbon emissions • Decreases reliance on fossil fuels and helps combat climate change • 💰 Cost Savings on Bills • Cuts down on electricity or gas expenses • After initial setup, sunlight is free — saving money long-term • Government subsidies available in some areas • 🔧 Low Maintenance & Long Lifespan • Fewer moving parts = minimal wear and tear • Requiresoccasional cleaning and routine checks only • Can last 15–20 years with proper care • 🔌 Energy Independence • Reduces dependence on grid electricity or gas supply • Reliable hot waterevenduring power outages or fuel shortages • ♻️SupportsGreen Living • Adds value to eco-conscious homes • A step towardsustainable, off-gridliving

5. Major Components • A solar water heater system has five main parts working together to heat and store water: • Solar Collectors—Roof-mountedpanelsthat absorb sunlight and convert it into heat. • Storage Tank—Stores the hot water for lateruse. • Heat Exchanger—Transfers heat from the solar-heated fluidto the water. • Controller System – Regulates temperature and prevents overheating. • Backup Heater—Ensures hot water availability during cloudy or low-sunlight days. • Together, these components create an efficient system that reduces energy consumption and ensures a constant supply of hot water using clean, renewable energy.

6. How Solar Collectors Work • Solar collectors are the primary component responsible for capturing sunlight and converting it into heat. These collectors are typically installed on the roof, where they receive maximumexposure to the sun throughout the day. When sunlight hits the glass surface of the collector, it passes through to an absorber plate beneath. This plateabsorbs the sun’s energy and heats a transferfluid (usually water or antifreeze solution) that flows through pipes embedded in the plate. • There are two main types of collectors: • Flat Plate Collectors – Affordable, durable, and suitable for moderate climates • Evacuated Tube Collectors – Moreefficient in colder regions, but fragile and more expensive • These collectors ensure a constant supply of heat energy, which is then transferred to water via the system’s heat exchanger.

7. StorageTank& Heat Exchanger • Heatedfluid moves into the heat exchanger • Heat is transferred to the water • Hotwater stored in an insulated tank • Ready for use in showers, cleaning, laundry, etc. • StorageTank& Heat Exchanger • Heatedfluid moves into the heat exchanger • Heat is transferred to the water • Hotwater stored in an insulated tank • Ready for use in showers, cleaning, laundry, etc.
