With the current rise in electricity and gas prices, more people in Pakistan are turning to solar water heater systems as an alternative for water heating. Solar water heaters, also known as solar geysers or solar water heater panels, are an innovative technology that is gradually gaining popularity in the country. These systems utilize the sun’s energy to generate heat, which is then used to warm water for various purposes in homes and businesses.

Compared to traditional electric or gas geysers, solar water heaters offer several advantages, including cost-effectiveness and efficient performance. In this blog post, we will provide a clear and easy-to-understand explanation of solar water heaters. We will discuss what they are, how they work, and the potential savings you can enjoy by switching from conventional heating methods. Additionally, we will provide an overview of water heaters in general to ensure a comprehensive understanding of the topic.

What Is A Solar Water Heater?

A solar water heater is a device used to generate heat for water heating purposes. It typically consists of solar collectors that absorb sunlight and convert solar power into heat through a solar thermal collector. Solar water heaters provide a cost-effective and environmentally friendly method for warming water.

How does Solar Water Heater Work?

A solar water heater system works by using solar thermal panels, also known as solar thermal collectors, to capture the energy from the sun. These collectors are typically made of metal or plastic and are designed to absorb the heat from sunlight. The absorbed heat is then transferred to a special fluid, such as water, which is circulated through pipes to a storage tank. Inside the tank, the heat from the fluid warms up the water, providing hot water for various uses.

Confused About Solar Thermal Collectors?

Let’s clear up the confusion about what solar collectors are and how they work.If you examine solar thermal panels or solar water heater panels closely, you will see rows of pipes filled with fluid—such as water, oil, or antifreeze. These rows of pipes are known as collectors and play a crucial role in heating the water. Now, let’s understand how they work. These collectors absorb energy from the sun and are designed to efficiently capture and transfer heat to the water tank, thereby warming the water.

Difference between Solar Panels and Solar Water Heater Panels

It might be confusing to know the difference between solar panels that generate electricity and solar water heater panels that heat water. They are different technologies, as solar water heaters are often called solar thermal panels. Unlike solar panels, solar thermal panels contain solar collectors that absorb heat and transfer it to warm water. Solar panels, on the other hand, contain photovoltaic cells that produce electricity to power home appliances and commercial businesses.

Price of Solar Water Heater in Pakistan

The price of a solar water heater in Pakistan can vary depending on factors such as size, capacity, and brand. However, a commonly used solar water heater in Pakistan can cost between Rs. 100,000 to Rs. 120,000, while a high-end solar water heater can range from Rs. 130,000 to Rs. 150,000.

Here are some of the factors that can affect the cost of a solar water heater:

Size: The larger the solar water heater, the more expensive it will be.
Capacity: The higher the capacity, the more water the solar water heater can heat at once.
Brand: Some brands are more expensive than others.
Features: Some solar water heaters have additional features, such as thermostats and timers, which can increase the cost.
It is important to note that the cost of a solar water heater may also vary depending on the region in Pakistan. For example, solar water heaters in Karachi may be more expensive than solar water heaters in Lahore.

Here is an estimated price table for a Solar Water Heaters in Pakistan

Tank capacity in liters Estimated price
150 100k – 120k
200 130 -150k
300 180k – 200k

Summary

Solar water heaters system is quietly a new concept of heating the water in Pakistan. But somehow it is evolving with some pace. Solar water heaters are relatively cheaper and environment friendly than the electric or gas geyser which are used to heat up the water. the price of solar water heater in Pakistan is not too high as solar water heater with 150 litter tanks can be bought in Rs. 100,000 to 120,000.
