What Is a Solar Water Heater?

Solar water heater it absorbs the energy of the sunlight to produce electricity.

solar water heating systems are the collectors that are attached to your roof which observes heat energy directly from the sun and which helping to heat water for daily uses.

Solar water heating systems are called solar panels, collectors, which are set to your roof. They have used to absorbs the heat from the sun and use it to heat water which is stored in a hot water cylinder. A boiler or immersion heater can be used as a back-up and can be heated to further water to reach the desired temperature.

Why We Need a Solar Water Heater?

Most of the energy is used in heating up water in all homes. In fact, nearly 18 percent of home energy consumption goes to heating water, According to the Department of Energy. It is possible to reduce fuel consumption and affordable costs, making it possible to switch to the home solar water heating system.

Such a system does not rely on fossil fuels and takes up water from the sun. Hence the main advantage of solar heating systems is to save money. Energy from the sun does not cost anything, so there is no charge from electric utilities.

Uses of a Solar water heater

→After installation, requires minimal maintenance, and a solar water heater can run up to 20 years.

→It is purely eco-friendly renewable energy.

→80 percent of the Sun’s radiation has been converted to hot water for the home needs.

→You also save fuel bills to supply gas heating systems.

→Reduce electricity bill on your home

About Solar Water Heater

A sun-facing collector then heats up a working fluid into a storage system to work. SWH active (pump) and passive (convex-driven). They only use water, or both water and a working fluid. They are heated either directly or light-centered glasses. They work independently or hybrids with electric or gas heaters. In large-scale installations, glasses turn sunlight into a small collector.

The powerful incoming thermal radiation energy from the sun heats the water in the solar collectors. Then the water flows through a heat exchanger in the storage tank, which helps in transforming the heat to the water. cold water in the storage tank
directly circulates water through solar collectors, which converts cold water into hot water by thermal energy from the sun directly

Solar Water Heater Working Function During Night

Usually, a solar water heater is made up of the backup gas or electric water heater Because they are two purposes
1. Heating water on days even there is no sunlight or not enough
2. increasing in heating up water if it’s not hot enough
So, Backing unit is more helpful in heating cold water when the water is not enough.
Well, the gas or electric backup unit should hardly work at all time. The hot water is stored in a protective insulated tank, preventing the water from cooling down too much before it’s used. The backup unit will provide just addition of heat to keep the water warm
save up to 75% to 90% on your water heater bill by using your solar water heater
The energy emitted by the sun, the sun’s rays are made of heat and sunlight.

The thermal energy produced by the sun’s rays is nothing but sunlight and heat that can be reproduced, captured, transformed and used to heat water.
