How Does Solar-Powered Water Heater Work?
Solar-powered water heaters have become increasingly popular among homeowners. Unlike traditional water heaters, these systems utilize the power of the sun to heat up water in your house. If you're considering installing one, it is important to understand how solar-powered water heaters work.
The following is a breakdown of how this innovative system works and how it can benefit you.
The Basics: How Does It Work?
Heating water is one of the highest energy expenditures in most homes. Solar water heaters offer a new way to reduce energy consumption. The solar-powered water heater, as with any other solar-powered system, works by harnessing the power of the sun.
Most solar-powered water heaters use flat-plate collectors or evacuated tubes to collect the sun's energy. In a flat-plate collector system, a flat, rectangular box with a glass top is installed onto a roof or ground-mounted. Inside this box, there is a dark-colored absorber plate that is positioned to maximize exposure to the sun. This plate conducts the heat to the water running through pipes beneath it.
The evacuated tube system works like this: a row of glass tubes is connected to a manifold at the top of each tube. At the bottom, each tube has a metal rod that extends down into the tube. Similar to the flat-plate collector, an absorber plate is fitted into each manifold, and the tubes are coated with a special surface to improve their heat absorption properties.
How Energy is Stored and Distributed.
Both of these methods provide a similar product: hot water. Once the solar collector system converts the sunlight into usable thermal energy, this energy is stored either in a hot water tank or used instantly to heat water as it flows through the system. The water is typically stored in an insulated tank that keeps the water hot until it's ready to use. A differential controller controls this process, determining when to activate the pump that moves water through the collector.
The Benefits of Solar Water Heating.
Investing in a solar water heating system is an investment that is worth it. Installing solar-powered water heaters comes with many benefits, including:
1. Decreased Dependence on Fossil Fuels.
When you install a solar water heater, you are decreasing your dependence on fossil fuel, reducing greenhouse gas emissions, and contributing to a clean environment.
2. Reduce Energy Bills.
The cost of electricity and gas continues to rise steadily, making people look for more affordable energy alternatives. In most areas, sunlight is free and available all year round, so investing in a solar-powered water heater can save you money in the long term by reducing your energy bills.
3. Increase Your Property Value.
According to the National Renewable Energy Laboratory (NREL), adding a solar water heater system to your home increases its overall property value.
Conclusion.
Solar water heating is an excellent way to use sustainable energy to heat your home's water. The process is simple, and the cost savings are hard to ignore. With the environmental benefits and potential energy savings, it's no wonder that more and more people are opting for these systems.
